KG 13 Chapter 2 Working with Flasher This chapter describes functionality of Flasher and how to use it. UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 14 CHAPTER 2 2.1 Working with Flasher Connecting Flasher to the PC 2.1.1 Using the RS-232 interface with a serial COM port Flasher comes with a standard serial 1 by 1 interface cable with one male and one female 9 pin SUB-D9 connector which can be used to connect the Flasher to the PC. The pin assignment of the 9 pin SUB-D female RS-232 interface connector is as follows: Pin no. 2 3 5 Signal TxD RxD GND Function Host signal Serial async. data input Serial async. data output Signal ground Serial data output (TxD) Serial data input (RxD) Signal ground Table 2.1: RS-232 signals Getting started 1. 2. 3. 4. 5. 2.1.2 Connect the Flasher to the power supply. Connect the Flasher to a PC using the 1 by 1 RS-232 serial interface cable and run the Flasher PC software FLASHER.EXE Select the chosen COM port of your PC in the communication settings dialog in the Flasher PC software by menu: "Options | Communication". Set up the device via menu "Options | Device" in the PC software. For in-circuit programming: Connect the Flasher to the target system via the standard 10 pin or customized interface cable. Using the RJ45 Ethernet interface Flasher comes with an RJ54 Ethernet cable which can be used to communicate via Ethernet. The cable can be plugged in directly into an RJ45 socket on the PC or elsewhere in the LAN using hubs or switches. Getting started 1. 2. 3. 4. 5. Connect the FLASHER to the power supply. Connect the FLASHER to a PC or LAN using the RJ45 Ethernet cable and run the Flasher PC software FLASHER.EXE Select the Flasher in the communication settings dialog in the Flasher PC software by menu: "Options | Communication". Details how to select the Flasher with Ethernet connection are described later on in the manual. Set up the device via menu "Options | Device" in the PC software. For in-circuit programming: Connect the Flasher to the target system via the standard 10pin or customized interface cable. UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 15 2.2 Using the Flasher PC software General Flasher comes with an easy to use Windows software. It allows reading of program files in motorola, intel hex or binary format. The following is a screenshot of FLASHER.EXE with loaded target program. Setup the communication between PC and Flasher Make sure that the power supply is connected (one of Flasher LEDs should be illuminated) and that the Flasher is connected to your PC with either the 9pin 1 by 1 RS232 serial interface cable, or the Ethernet cable. Both interfaces can be connected at the same time. It depends on the configuration, which interface is used to communicate. The Ethernet interface is much faster than the serial RS-232 interface, but may require additional configuration of the Flasher. 2.2.1 Setup the serial UART connection for communication The RS-232 port of the Flasher can be used for communication to PC. You have to select a COM port on your PC and set up the Flasher PC software to use this COM port. 1. 2. 3. 4. Connect the Flasher to a COM port of your PC via the provided serial cable. Chose menu "Options | Communication" to open the setup dialog for the communication parameters. Select the "UART Port" radio button. In the corresponding listbox select the COM port which is connected to your Flasher. You may chose COM1 to COM20. If this does not match any of your COM ports, you may try to assign a port number in the range from 1 to 20 in your Sys- UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 16 CHAPTER 2 Working with Flasher tem settings to the COM port you want to use. After the COM port selection, press OK. The Flasher PC software and Flasher should now communicate. The Flasher status and serial number should be visible in the Flasher PC software. 2.2.2 Setup the Ethernet connection for communication Using the Ethernet for communication has the advantage that download and upload of data between the Flasher and PC is much faster. Since Flasher software version 2.10, communication between Flasher PC software and Flasher via Ethernet is supported. A Flasher with firmware older than version 2.10 requires a firmware update which can be done via the RS-232 port. Initially, the Flasher retrieves its IP address from a DHPC server. Therefore, the connection between the Flasher and the PC requires a LAN with an active DHCP server to communicate unless a fixed IP address has been assigned to the Flasher. When the Flasher and the PC are connected to a hub or switch in the same LAN with DHCP server, the Flasher can be accessed by your PC without further configuration. 1. 2. 3. 4. Connect the Flasher to a hub or switch in your LAN using the RJ45 cable. It may take a few seconds until the Flasher gets its IP address from your DHCP server. In the Flasher PC software chose menu "Options | Communication" to open the setup dialog for communication parameters. Depending on the desired connection mode select "IP Addr" or "IP S/N" radio button. If "IP Addr" radio button is selected the Flasher PC software connects to Flasher using the IP address of Flasher. The IP address can be specified on the edit field on the right in the "dotted" format. If the "IP S/N" radio button is selected the Flasher PC software uses the serial number of the Flasher to connect to it. The serial number can be found on the label at the bottom of the Flasher. The edit field on the right can be used to specify the serial number of the Flasher to connect to. Click "OK" button to confirm your settings. UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 17 You may click the "Search..." button to scan the network for your connected Flasher. A list with Flasher which are found in your network is shown: Select one Flasher in the list and click OK (or double-click on one Flasher in the list). All available data of the selected Flasher is automatically read into the communication parameters dialog. At least the serial number and the IP address are available. When used in a LAN with DHCP server, it is a good choice to address and identify the Flasher by its serial number. 2.2.3 Setup the Network configuration for Flasher It may be useful to assign a fixed IP address and a nickname to the Flasher, which can be done by the network configuration for the Flasher. Fixed IP addresses have to be used when the Flasher should be driven in a network without DHCP server, for example, if it shall be directly connected to a PC or Laptop without DHCP server. Note that with version 2.10 of the Flasher PC software, this configuration settings can not be set from the Flasher PC software. Network configuration for the Flasher from the Flasher PC software will be implemented in later versions of the Flasher PC software. To configure the network settings of Flasher version 2.10, you have to use the built in web-server of Flasher 5 PRO. For first time setup, connect the Flasher to a LAN with DHCP server. To start the web server, you have to examine the IP address of the connected Flasher. To get the IP address, you may use the Flasher PC software and UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 18 CHAPTER 2 Working with Flasher retrieve the IP address from the programmer selection list as described above, or you may start the 5PRO_UDPDiscover.exe tool which is located in the program folder of the Flasher PC software. After examining the IP address of the Flasher to configure, start a web browser and enter the IP address in the address bar of your browser. Using the example above, you have to type 192.168.11.151 in the address bar of your browser. The browser will connect to the Flasher and show the main web-page. In the web server window, chose the function "Network configuration" by a click of the link shown on the left side. When you want to assign a nickname and a fixed IP address, first enter the nickname and press the "Save" button assigned to the nickname. Then enter the IP address and the subnet mask and press the "Save" button assigned to the IP address settings. There is no need to enter an IP address for a gateway. When you modify the IP address and save the settings, you will lose the connection. It is a good idea to write down the address you assigned. Be careful to assign an address which you can reach with your PC or laptop. The screenshot below shows a sample configuration to assign a fixed IP address and a nickname to the Flasher: UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 19 The sample above shows a configuration which was used to setup Flasher for a direct connection between a laptop and Flasher. The laptop had the IP address 169.254.98.109, the IP address for Flasher has to differ from the IP address of the PC it should be used with, but has to be in the same subnet. 2.2.4 Setup the USB connection for communication Since the software version 2.10 Flasher supports communication via USB. Communication via USB has the advantage of being faster than communication via UART. A Flasher with firmware older than version 2.10 requires a firmware update which can be done via the RS-232 port. The following steps must be followed in order to connect the Flasher to PC via USB: 1. 2. 3. 4. Connect the Flasher to an USB port of your PC or to a USB hub connected to your PC using the provided USB cable. Chose menu "Options | Communication" to open the setup dialog for the communication parameters. Select the "USB S/N" radio button. In the corresponding edit field specify the serial number of the Flasher you want to connect to. UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 20 CHAPTER 2 5. Working with Flasher Click "OK" button to confirm your settings. You may click the "Search..." button to scan the USB ports for your connected Flasher. A list with Flasher devices which are found is shown: Select one Flasher in the list and click OK (or double-click on one Flasher in the list). The serial number of the selected Flasher is automatically read into the communication parameters dialog. UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 21 2.2.5 First time setup of Flasher When using Flasher for the first time, please select the menu point "Options | Device". You will see the following dialog box: The device properties dialog allows selection of the chip area you would like to access, the sectors of the on chip-flash and the interface you would like to use. The serial interface requires a cable to connect Flasher to your target. For targets running at low frequencies, it may be necessary to set the "Speed" option to "Slow". To select an other device, press the "Select Device" button. The device selection dialog will open. You can select the group in a dropdown list and the specific device from the list below. Now you should be able to blank check, clear, program, verify or read the target chip in serial mode (if your target is properly connected to Flasher). The first time you program or verify, the PC downloads your target program to Flasher, where it is stored in the on board RAM chip for programming or verification. The PC Software stores all setup information in an FLASHER.INI; when you start the program the next time, it will start with the same settings. UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 22 CHAPTER 2 2.2.6 Working with Flasher Program, clear, verify and blank check Select one of the commands in the "Target" menu to start the operation. Note that some of the menu points may be grayed if you have no connection to the target or no file loaded. A modal dialog box will indicate the status and progress of the operation; the operation can be stopped any time by hitting the "Cancel" button. 2.2.7 Setup The operating mode of Flasher may be changed using the "Setup" dialog from the "Options" menu. Power up mode, Power down mode and Reset mode should not be changed for normal operation. You may change the reset active and reset inactive UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 23 time, if required by your target hardware. You may select reset output mode as PushPull output or Open Drain. All setup settings are stored permanently in Flasher after pressing "Save setup" button. 2.2.8 Additional options The "Filling & Misc." settings from the "Options" menu may be altered if required. Normally there is no need to change any of these settings. Improper setting of fill byte may lock your target CPU! When programming blank (virgin) CPUs the option "Automatic clear before program" is not required, so this feature can be disabled to speed up programming procedure. "Detailed errorlevel on return" option may be used to return a detailed error code to the calling program when Flasher is used in batch mode. 2.2.9 ID check When programming Renesas CPUs in serial mode (in target), an identification of up to 15 bytes has to be supplied. If the target MCUs user program area is blank, this ID-value does not matter. However, after programming, these values need to be set correctly, because otherwise Flasher will be unable to communicate with the target CPU. These ID-values can be set using the menu point "Options | Passcode". With a standard program, these values should be 0, as the high bytes of the interrupt vectors which are used to store the values are usually 0. UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 24 CHAPTER 2 Working with Flasher For more detailed information, please consult the Renesas users manual. The menu point "Edit | Copy passcode into loaded file" can be used to copy these ID bytes into your application program. Problems with ID check You should act carefully when programming ID bytes. If you do not know the IDvalue programmed into a target chip, there is no way to erase, read or reprogram the chip in-circuit later. We recommend not to use this feature during the development process. UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 25 2.3 Using the serial link to program in circuit Flasher can be used for in circuit programming of supported CPUs, which incorporate built in firmware for serial update of user flash. The target system has to be designed to support this mode of operation. Refer to target specific connection diagrams or Users manuals of your target CPU. UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 26 2.4 CHAPTER 2 Working with Flasher Operating Flasher in stand-alone mode After downloading the target program, all settings are stored in Flasher on board flash memory and remain valid until new settings or data are sent to Flasher. Any number of microcontrollers may now be programmed by Flasher (one at a time) without the need of a host PC, by simply pressing the start button. Flasher will use the settings which have been made in the PC software. This includes the selection of target address range as well as any options. Whether the target CPU will be erased before programming depends on setting of option "Automatic clear before program". Progress and result of the operation is indicated by Flasher LEDs as follows: LED status GREEN, flashing GREEN RED Meaning Erasing / Programming / Verifying operation in progress. Programming operation successful. Programming operation failed Table 2.2: LED status UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 27 2.5 Error messages The following error messages can occur during operation of Flasher (shown in red on your PC) or returned as errorlevel when operated from batch file and "Detailed errorlevel on return" option is set. Code Error message 1 2 Erase failed Write failed 3 Verify failed 4 Blank check failed 5 Flash write/erase timed out 6 Can not write into this memory area 7 Canceled 21 Version read failure: Rx line problem ? 30 No ID 31 ID mismatch 32 ID mismatch 40 Target chip says "BUSY" 41 Target chip says BUSY Meaning/remedy Erase operation has failed. Write operation has failed. Verification failed. Loaded Program and contents of the flash-memory are not identical. Chip is not blank. Could not write into flash memory, the max. waiting time has been exceeded. In serial mode, the boot area of Renesas CPUs can be read out, but can not be written to. Last operation has been canceled by user. In serial mode, Flasher reads out the version of Renesas target CPUs bootloader. If this is not the right format (VER?.), a read line failure is most likely. Renesas target CPU has no valid ID (This error should not occur). Renesas bootloader (target CPU) requires the correct ID. Without it, you will be unable to access, read out, clear, or program the contents of the flash memory. The requested ID depends on ID previously written into the target CPU. For more information, please refer to the section "ID code check function" of the CPUs users manual. Same as Error 31 Renesas target chip has BUSY signal high (active). Most likely CPU did not enter bootmode. Check all signals to target. Refer to CPUs users manual about conditions to enter bootmode. Renesas target chip keep its Busy signal set (active) during communication. This inhibits communication between FLASHER and target. Some possible reasons: 1. RESET is not released 2. Target did not enter the serial I/O mode because the signals applied when RESET is released are not correct (EPM, CE, CNVSS) 3. No clock (check with oscilloscope) Table 2.3: List of error messages UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co.

KG 32 CHAPTER 3 3.1 Remote control Overview There are 3 ways to control Flasher operation: * * * Manual: Programming operation starts when pressing the button. The LEDs serve as visible indication. Via Handshake lines: 3 lines on the serial interface are used. 1 line is an input and can be used to start operation, 2 lines are outputs and serve as Busy and status output. Terminal communication via RS-232. UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 33 3.2 Handshake control FLASHER 5 can be remote controlled by automated testers without the need of a connection to PC and Flashers PC software. Therefore Flasher is equipped with additional hardware control functions, which are connected to the SUBD9 male connector, normally used as RS-232 interface to PC. The following diagram shows the internal remote control circuitry of Flasher: Pin No. Function 1 START 4 BUSY 7 OK 5 GND Description A positive pulse of any voltage between 5 and 30V with duration of min. 30 ms starts the "Auto" function (Clear / Program / Verify) on falling edge of pulse. Whether Clear is executed depends on Options | Filling & Misc. | Automatic clear before program. As soon as Auto-Function is started, BUSY becomes active, which means that transistor is switched OFF. This output reflects result of last action. It is valid after BUSY turned back to passive state. The output transistor is switched ON to reflect OK state.

KG 34 CHAPTER 3 3.3 Remote control ASCII command interface 3.3.1 Introduction Flasher supports a simple ASCII command interface via RS-232. Once set up using Flasher PC software, Flasher can be driven by any application or just a simple terminal using ASCII commands. Every known command is acknowledged by Flasher and then executed. After command execution, Flasher sends an ASCII reply message. If an unknown command is received, Flasher responds with #NACK. General command and reply message format Any ASCII command has to start with the start delimiter #. Any ASCII command has to end with simple carriage return (ASCII code 13).Commands can be sent upper or lower case. Reply messages from Flasher are sent back using the same format. All characters are upper case in reply messages. Communication port settings Flasher is driven via RS-232 serial port with the following interface settings: * * * * 3.3.2 8 data bits ODD parity 1 stop bit 115200 baud Commands to Flasher The following commands are supported by current version of Flasher firmware: #AUTO The Auto command behaves exactly as the start button or external remote control input. * * * * Flasher Flasher Flasher Flasher starts clearing target, if "Automatic clear before program" option was set. programs target CPU. verifies target CPU. verifies its internal CRC to validate the programming operation. Finally, Flasher responds with: * * #OK if no error occurred #ERRxxx if any error occurred during operation. xxx represents the error code, normally replied to Flasher PC software. The #ERRxxx message may be followed by an additional error text. During execution of the AUTO command, Flasher automatically sends "status" messages via RS-232 to reflect the state of execution. Typically during execution of #AUTO command, Flasher will reply the following sequence of messages: #ACK #STATUS:START CMD #STATUS:CONNECTING #STATUS:CLEARING #STATUS:WRITING #STATUS:VERIFYING #STATUS:VERIFY FLASHER CRC #STATUS:READY #OK #AUTO NOINFO This command may be used instead of AUTO, if no status messages from Flasher should be sent during execution. The command ends with #OK or #ERRxxx UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 35 #BLANK This command can be sent to perform a blank check over all selected target Flash sectors. Flasher will reply the following sequence of messages: #ACK #STATUS:START CMD #STATUS:CONNECTING #STATUS:RESET #STATUS:CONNECTING #STATUS:BLANK CHECK #STATUS:READY #OK in case of blank check failure, Flasher will respond with: #ERR004:BLANK CHECK FAILED. #CLEAR This command can be sent to clear all selected target Flash sectors. Flasher will reply the following sequence of messages: #ACK #STATUS:START CMD #STATUS:CONNECTING #STATUS:RESET #STATUS:CONNECTING #STATUS:CLEARING #STATUS:READY #OK in case of an erase failure, Flasher will respond with: #ERR001:ERASE FAILED. or an other error message if any communication error occurred. #START This command can be sent to release Flashers target interface. All signals from Flasher to target will be set into high-Z mode, reset of target will be released. May be used to start target application program. Flasher will reply the following sequence of messages: #ACK #STATUS:START CMD #STATUS:READY #OK #CRC This command is useful to identify or verify Flasher internal data which should be programmed to target CPU. Flasher responds with the CRC of its current memory content: * * #CRC:xxxx if data is present. xxxx is a 4 digit HEX number. #CRC:---- if no valid data is present in Flasher memory #STATUS This command can be sent any time, even during other command execution. Flasher responds with its current state. All defined state messages are described under Reply messages from Flasher on page 37 later on in this manual.

KG 36 CHAPTER 3 Remote control #PROGRAM This command can used instead of #AUTO to program a target without final verification. Whether the target is cleared before programming depends on options which were set during configuration using the Flasher PC software. #VERIFY This command can used to verify the target Flash content against the data stored in Flasher. #RESULT This command can be sent any time, even during other command execution. Flasher responds with the last result of a previous executed command, or the result of a running command. #CANCEL This command can be sent to abort a running program. It may take a while until the current program is actually canceled. Flasher will respond with: #ERR007:CANCELD.

KG 37 3.4 Reply messages from Flasher The reply messages from Flasher follow the same data format as commands. Any reply message starts with ASCII start delimiter #. Any reply message ends with simple carriage return (ASCCI code 13). The following reply messages from Flasher are defined: #ACK Flasher replies with #ACK message on reception of any defined command before the command itself is executed. #NACK Flasher replies with #NACK, if an undefined command was received. #OK Flasher replies with #OK, if a command other then #CRC, #STATUS or #RESULT was executed and ended with no error. #CRC:xxxx Flasher replies with #CRC: after calculating the CRC of its internal data memory. The CRC xxxx is sent back as four digit HEX number. If Flasher does not contain valid data, Flasher replies with #CRC:----. #STATUS: Flasher replies with its current state. The following status messages are currently defined: Message #STATUS:READY #STATUS:INITIALIZING #STATUS:CLEARING #STATUS:WRITING #STATUS:READING #STATUS:VERIFYING #STATUS:BLANK CHECK #STATUS:IDLE #STATUS:START CMD #STATUS:ERASE-VERIFY #STATUS:VERIFY FLASHER CRC #STATUS:CONNECTING Description Flasher is ready to receive a new command.

KG 49 If the RESET of the target system is driven by a reset circuitry with active high driver, the RESET output of Flasher must not be connected directly to the CPU reset of the target. For M16C/62 or M16C/80 targets you do not have to connect RESET to Flasher; you can always manually reset your target system after connecting Flasher. Caution: Before connecting the target with Flasher, ensure that there is NO difference in the ground potential between Flasher and target. When the Flasher is connected to a PC via RS232C cable, ensure that the PC and the target operate on the same ground potential. Connect the ground lines from PC and your target before connecting the Flasher to the target. If a ground potential difference between Flasher and target exists, the Flasher may be damaged. 5.1.1 Serial programming, technical details for M16C/6x, M16C/80, R32C Serial programming uses a clock synchronous interface. 8 bits of data (1 byte) is transferred at a time. The commands which are used are described in the Renesas manuals. In general, the sequence is as follows: Flasher resets the target system by pulling the /Reset line low for a period of time which is set as Reset active time in "Options | Setup" dialog of PC software. Flasher waits for the Reset inactive time, nominal 500 ms, (tRD) in order to allow the target system to recover from reset. This time can also be set in "Options | Setup" dialog via PC software. UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 50 CHAPTER 5 Hardware Flasher checks the BUSY line. If it is active (high level) Flasher stops with the error message 40: Target chip says "BUSY" because it can not communicate with the target system. Flasher outputs one clock (clock changes from high to low and back). BUSY should now be active (high). If it is not active, Flasher stops with error message 41: Target chip: Busy does not react. Flasher outputs 7 more data bits (7 clock cycles) and waits for BUSY to go low. More data bytes are output (or read) the same way. t RL: nominal 20 ms t RD: nominal 500 ms The reset active time (tRL) and reset inactive (e.g. reset delay) time (tRD) can be set in "Options | Setup" dialog if required.

KG 53 5.4 CRC calculation used in Flasher and PC software The Flasher PC software and Flasher calculate a CRC over all data downloaded to the Flasher. The CRC is used to verify correct data transfer as well as an integrity check of target-data stored in the on board non-volatile memory. The CRC is calculated over all bytes of all selected flash sectors of the target device. The calculation is compatible to the algorithm used in the CRC generator circuit inside a Renesas M16C/62P device. The Renesas application note REU05B00070100Z describes how the CRC is calculated. To calculate the CRC of a target application you have to perform the following steps: 1. 2. 3. 4. Create a buffer, large enough to hold all bytes of all selected flash banks of the target. Fill the whole buffer with the fill-byte which is defined as fill byte in the Flasher Filling & misc. options. Parse your hex-file and fill all defined bytes into the buffer. Bytes not defined in the hex-file were set to the fill byte in step 2. Calculate the CRC over the whole buffer following the algorithm from the application note, or the following sample code. Alternatively, the CRC over all bytes may be calculated without a buffer, when a function delivers all bytes of all selected flash banks, including fill bytes, in ascending address order from a stream. Example code for CRC calculation // // CRC_Calc1_M16() calculates the CRC for one byte. // Before calling the function the first time, set the CRC to 0x0000 // void CRC_Calc1_M16(unsigned int* pCRC, unsigned char Data) { unsigned int crc; unsigned int x16; int i; crc = *pCRC; for (i = 0; i < 8; i++) { if ((crc & 0x0001) ^ (Data & 0x01)) { x16 = 0x8408; } else { x16 = 0x0000; } crc = crc >> 1; crc ^= x16; Data = Data >> 1; } *pCRC = crc; } // // CRC_Calc() calculates the CRC over NumBytes bytes in a buffer // unsigned int CRC_Calc(unsigned char* pBuffer, unsigned long NumBytes) { unsigned int CRC_M16; unsigned long i; // // Initialize CRC and calculate the CRC over all bytes // CRC_M16 = 0x0000; for (i = 0; i < NumBytes; i++) { CRC_Calc1_M16(&CRC_M16, ((char) pBuffer[i])); } return CRC_M16; } // // The following example shows how to calculate the CRC over all bytes // in a buffer as described above using the CRC_Calc() function // unsigned long NumBytes; unsigned long i; unsigned char* pBuffer; unsigned char Fillbyte; unsigned int CRC; UM05009 User & Reference Guide for Flasher 5 PRO (c) 2010 - 2014 SEGGER Microcontroller GmbH & Co. KG 54 CHAPTER 5 Hardware NumBytes = SUM_OF_ALL_BYTES; // Number of bytes of all selected flash sectors // // Create a buffer for all bytes // pBuffer = (unsigned char*) malloc(NumBytes); // // Initialize the buffer, fill up with the fill bytes // if (pBuffer != NULL) { Fillbyte = FLASHER_FILL_BYTE; // The fill byte set in Flasher options memset(pBuffer, Fillbyte, NumBytes); // // Fill the buffer with data. This has to be done by a function that // parses the Hexfile and addresses the buffer according the address // offset which depends on the selected flash sectors // ParseFile(pBuffer, NumBytes); // // Initialize CRC and calculate CRC over all bytes in the buffer // CRC = CRC_Calc(pBuffer, NumBytes); } Remarks The first byte in the buffer has to be the first byte of the first selected flash sector, regardless the address of the sector. For example, if the first selected sector has address 0x3000, the first byte in the buffer (offset 0) is the byte at address 0x3000 in the target device. If the hex file addresses only some of the bytes in a flash sector, all the other bytes have to be filled up with the fill byte. For example, if the selected flash sector has 4096 bytes, starting from address 0x3000 and the hex-file only contains data for the first 16 bytes, the whole area from 0x3010 to 0x3FFF has to be filled up with the fill byte. All selected sectors are stored in ascending address order without any gap, regardless the start address of the flash sectors. For example, if the first sector starts at address 0x3000 and has a total size of 0x1000, the second selected sector starts at 0x8000 and has a total size of 0x1000, the buffer to hold the data needs a size of 0x2000 bytes. The first byte from the first sector is stored at offset 0 in the buffer, the first byte of sector 2 is stored at offset 0x1000.
