1. Introduction

LPCXpresso is a, l ow-cost development platform av ai lable from NXP. The software

consists of an enhanced, Eclipse-based IDE, a GNU C compiler, linker, libraries, and an

enhanced GDB debugger. The hardware consists of the LPCXpresso development board

which has an LPC-Link debug interface and an NXP LPC ARM-ba sed microcontroll er

target. LPCXpresso is an end-to-end solution enabli ng em bedded engine ers to develop

their applications f rom initial evaluation to final production.

The LPCXpresso IDE , powered by Code Red Technologies (http://lpcxpresso.code-red-

tech.com), is bas ed on the popular Eclipse development platform and includes several

LPC-specific enhancements. It is an industry-standard GNU t ool-chain with an opt im i zed

C library th at gives engineers all the tools necess ary to develop high-quality softwar e

solutions quickly and cost-effectively. The C programming environ m ent includes

professional-level features. There is syntax coloring, source formatting, function folding,

on- and offline help, and extensive project m anagement automation.

The LPCXpresso target board, jointly developed by NXP , Code Red Technologies, and

Embedded Arti st s (http://www.embeddedartists.com/products/lpcxpresso/), includes an

integrated JTAG debugger (LPC-Link), so there’s no n eed for a separate JTA G debug

probe. The target portion of the board can connect t o expansion board s t o prov i de a

greater variety of interfaces, and I/O devices. The on-board LPC-L ink debug ger provide s

a high-speed USB to JTAG/SWD interface to the IDE and it can be connected t o other

debug targets suc h as a customer prototype. Users ca n also use the LPCXpresso IDE

with the Red Probe JTA G adapter from Code Red Technologies.

1.4 LPC-LINK JTAG/SWD debugger

The LPCXpresso boa rd contains a JTAG/SWD debugger called the “LPC-Link” and a

target MCU. LPC-Link is equipped with a 10-pin JTAG header (highlighted on the abov e

image) and it seaml essly connects to t he target via USB (the USB interface and other

debug features are provided by NXP’ s ARM9 based LPC3154 MCU). Cutting t he tracks

between the LPC-link and the target will m ake t he LPC-Link a stand-alone JT A G

debugger. Thi s enables the LPCXpresso platform to be connected to an external target

and used to develop for a wide variet y of NXP’s Corte x-M0, Cortex-M3, and ARM7/9

based applications. Currently supported microcontroller produ ct s include LPC800,

LPC1100, LPC1200, LPC1300, LPC1700, LPC1800, LPC4000, LP C4300 series and

specific members of the LPC200 0 and LPC3000 fam i l ies.

1.5 Integrated evaluation target

The target includes a small prototypi ng area and easily accessible connections for

expansion. The LP CXpresso board with target can be used

• On its own for software development and benchmarking

• Connected to an off-the-shelf base board for rapid proof-of-concepts

• Connected to customer-designed board for a full prototype

1.6 LPCXpresso partners

NXP has partnere d with Code Red Technologies and Em bedded Artists f or the

LPCXpresso platform. For added flex ibilit y and higher memory confi gurati ons, the

LPCXpresso platform can easily be upgraded to include full-blown suites from Code Red

Technologies and more advance d hardware kits fr om Embedded Artists. Please v i sit the

LPCXpresso webpage for more information.

2. Evaluate, explore and develop

Fig 3. Product development stages

Users can envisage three stages f rom evaluation to product development. During

evaluation, features and peripherals of the target MCU can be easily tested with the

prototyping area and easily accessible connection s on the target board. Complementi ng

the target board a re also easy-to-use example projects and a handy Getting Started

guide. For rapid proof-of-concepts, users can get an off-the-shelf base board from

Embedded Arti st s and quickly explore the next level of appli cat i ons. And finally

LPCXpresso users can seamles sly devel op their final applic ation by using the LPC-Link’s

10-pin JTAG connector to attach any J TAG-capable custom board. This way, users can

now enjoy the same user experience right from evaluation to prod uct development.

4. Getting famil iar with the LPCXpr esso IDE

LPCXpresso IDE i s based on the Eclipse IDE framew ork and many of t he core f eatures

are described well i n generic Eclipse do cumentation and in the help files found in the

help menu of the product. Further documentation and pointers to useful documents are

also available on the Code Red Technol ogi es Wiki at http://support.code-red-

tech.com/CodeRedWiki.

4.1 Layout of the LPCXpresso desktop

LPCXpresso’s Desktop contains ma ny windows. Each window is called a Vi ew, because

it displays a particular view of data in the LPCXpresso env i ronment. This data could be

source code, hex dumps, disassembly, memory cont ents, or more. V i ews can be

opened, moved, doc ked, and closed, and the layout of the currently displayed Views can

be saved and restored. A specific configuration of Vi ews is called a ‘Perspective.’

Typically, LPCXpresso operate s in a single perspective under which both the code

development & debug sessions operat e as shown on the next page. The single

perspective greatly simplifies t he E cli pse environment and enhances the entire

LPCXpresso experienc e.

All Views in the Per spective can be moved around by dragging and dropping. I f a View is

accidentally c l osed, it can be restored by selecting it from the Show View dialog. The

Show View dialog c an be opened from the S how V i ew Other... option in the Window

menu.

5.3 Working with Instruction Trace

Instruction tra ce provides the abilit y to record and review the sequence of i nst ructions

executed on a t arget . LPCXpresso 5 introduces support for instruction t rac e via on board

trace buffers. Instruction trace makes use of the E m bedde d Trace B uff er (ETB) on

Cortex M3 and M 4 parts and the Micr o Trace Buffer ( M T B ) on the Cortex-M0+. The

instruction trace which is generated at high speed can be captured i n real time and

stored in these on-chip buffers, so that they can be downloaded at lower speeds without

the need for additional debug hardware.

For informati on on how to configure LP CX presso 5 to work wit h Instruction T race, please

refer to the “Getting Started with Red Trace guide” that is available f or download from the

Code Red support website:

http://support.code-red-tech.com/CodeRedWiki/NewInVersion5

Please note that onl y the Instruction Trace part of the guide is applicable to the

LPCXpresso-IDE.

6. LPCXpresso IDE tips and tricks

6.1 Installing Eclipse plugins

The LPCXpresso IDE contains many of the features of the Eclipse open-source IDE from

http://www.eclipse.org. The browse and install plugin functi on is present in t he help

menu. To access it , choose Help -> Insta ll New Software. This wil l display the Ecli pse

Install Softwa re di al og which will all ow browsing and installing of Eclipse plugins.

6.2 Debugging tips

6.2.1 Debug features not enabled

All of the LPCXpresso features are co ntext-sensitive. If features are disa bl ed, double-

check that you are nav i gated into a .c fil e i n an open project on the Project Explorer

View, or some menu items and toolbar buttons may be disabled. If your workspace

contains projects t hat create l ibraries such as CMSI S , please note that debug features

will be disabled if you are currently editing a .c file that i s part of a library project.

6.2.2 Error launching debug\filename.axf

Fig 23. Error starting debug

LPCXpresso checks the target chip ID against the currently selecte d chip ID for the

project and wil l not start if there is not a m atch. Make sure that t he cor rect NXP LPC

microcontroller part is selected in LPCXpresso. The current part number is displayed in

the status bar at the bottom of the LP CX presso window. I t can be changed by ho l di ng

down the Ctrl key and clicking. A di alog wil l appear allowing sel ect ion of the corr ect part

6.2.3 Optimization issues

When optimizati on i s enabled, it will reorder code. What this means is t hat the code from

multiple C lines will be intermingled. In addition, assignments and i ni tializations mi ght be

pulled out of loops so they are only ex ecuted once. Changes like these will make the

code confusing to debug. Some symptoms you might see are breakpoints that only work

the first time t hrough, or seeing t he debugger’s cur rent line indicat or fail to advance or

even move backw ards when you cli ck step. It is best to always use –O0 for debu ggi ng.

Since optimization can make such a bi g difference in cod e size and performan ce, it is a

good idea to test y our project with opti m ization and plan for a final build that i s optimized.

6.2.4 Exiting debug mode and stopping debugging

To stop debug press the ‘ Stop’ button (r ed square) shown in the toolbar at the t op of the

debug view.

6.2.5 Recovery of board

After playing arou nd with the LPCXp resso board, esp ecial l y when trying out new PLL

settings, reco nfiguring the SWDIO/SWDCLK pin funct ions, disabling AHBCLK CTRL bits,

or trying power do wn m odes, the board may be disabl ed and no longer enter debug

mode. This is cau sed by code on the on-board flash that incorrectly disables t he system

clocks or the debug port soon after reset before the debugger can connect to t he core.

The easiest solut i on to this is to load a working project into LPCXpresso, ground t he ISP

pin (see the chip User’s Manual for details) and then try to enter debug mode.

Grounding the ISP pin during reset will put the target MCU into In-System Programming

(ISP) mode. It wil l wait for a command through the serial port or the USB port. This

temporarily prevents the trouble some code in flash fro m st art i ng. Although IS P is

designed to enable serial and USB updates, while ISP i s running, the LPCXpresso

toolchain is able t o connect to t he Cortex core and reprog ram the flash. After the flash is

reprogramme d, disconnect t he ISP pin (pull it high or allow it to float) and stop

debugging. Now you should be able to debug code again.

6.3 Datasheet brow ser

The LPCXpresso IDE comes with an integrated web browser that will direct vi ewer s to

6.4 Code size

6.4.1 printf

When optimizing a project for size, if you are using print f, make sure that Redli b is

selected as the standard library in t he P roj ects Properties dialog. This option can be set

using the Quick Settings dropdown b ox in the Quick Start panel.

Fig 27. Reconfigure library setting

The printf implementation in Redlib i s about half the size of the implement ation in Newlib.

A smaller printf library can be used in Redlib if floating point formatting st rings are not

used. To select thi s smaller library, def i ne the symbol CR _INTEGER_PRI NTF to the

compiler (i.e. -DCR_INTEGER_PRINTF). To sav e even more space , avoid using printf or

any C standard library functions and select Redlib (none). Depending on your printf

settings and code, this could free up 1 0 K t o 20K of flash memory.

6.4.2 Optimization

Optimization can d o a l ot to save flash mem ory . It can be configured in the same di alog

as the C standard library. Choos e “Optimization” under “MCU C C om pil er” in the “Tool

Settings” tab. Higher levels of opti m izat i on wi ll typically result i n hi gher performance, but

may result in large r code size. It i s best to use –O0 for debugging and higher levels for

Release. For best code size try –Os –mword-relocations. To further reduce code, add

--gc-sections to the proj ect linker flags. This causes the linker to remove unu sed

functions from the compiled code. --gc-sections is enabled by default in new projects

created by the proje ct wizard. If y ou are working with an ex ist i ng project, you may need

to manually add t hi s option to y our project. --gc-sections is safe to use in both Release

and Debug builds. There are many optimization opt i ons av ai lable for GCC. Visit

http://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html to see all of them.

6.5 Showing hidden views

A view is an on-screen re presentation of somet hi ng in the IDE. A view can be source

code, the project tree, or a debug wind ow. If you acci dentally close a v iew, you can open

it again by going to the Window menu and choosing Show View and Other. It is a good

idea to browse t hrough the Show View window to see what i s av ailable.

Fig 28. Show view window

This will present a di al og allowing you to pi ck a v i ew and display it.

7.3 Terminology

LPCXpresso

The Code Red Technol ogies IDE (Integrated Develo pm ent Environment) based on

Eclipse with our own extensions for embedded development.

SWD

Serial Wire Debuggi ng (S ingle Wire Debugging). This is a debug connection t echnology

available on the Cortex-M3 that all ows debug through just 2-wires unlike 5 for J T A G .

ELF (Executable and Linking Format)

This is the object code file format u sed by our development tool chain and most

microprocessor tool chai ns.

Workspace

LPCXpresso organi zes groups of projects into a ‘Work space’. A workspace is stored as a

directory on your host PC and has su bdi rectories contai ni ng indi vidual project s.

Project

An LPCXpresso project. A project cont ains all of the .c and .h files to build a single

microcontroller f l ash image.

Perspective

In LPCXpresso, a perspective is a part i cular collection of ‘Views’ that are grouped

together to be suitable for a particular use. For example the ‘C/C+ + programming’

perspective and the ‘Debug’ perspe ct i ve.

View

A ‘View’ is a window in LPCXpresso that shows a particular f i le or activity. A view could

be of a C source cod e file or something l i ve such as a disassembly window or register

dump. A ‘Perspe ct i ve’ is the layout of many ‘Views’.

Semi-hosting

The ability to use IO on your debugger host system for your target embedded system.

For example a ‘printf’ will appear in the console windo w of the debugger.

Debug Target

The system being debugged. LP CXpresso includes a target microcontroller on-board, but

can also be connect ed to external targets.

RedlibTM

The optimized Code Red Technologies C runtime library (non-GNU). L PCXpresso
