3.1 Bootloader
Bootloader for Mini3250 Linux system includes two parts, one is Stage 1 Loader, and the other is
Uboot.
The Stage 1 Loader (S1L) is a robust third level boot loader written by NXP Semiconductor to simplify
and enhance the LPC3250 booting procedure. The S1L is feature rich with the ability to configure
clocking, virtual memory mapping, data and instruction caches, the ability to access NAND flash, and
the ability to boot applications/images from the NAND flash, SD Card, or serial port to name a few of
the features the S1L provides.
Mini3250 adapt Uboot as the Bootloader for Linux. Uboot is a general free open source boot program
that supports many kinds of processors; it is similar to BIOS on PC but much more powerful. Uboot
supports features like booting from Ethernet and loading various kernels to NANDFLASH. Uboot is
free open source code software based on GPL.
3.2 Linux Kernel
If user need add or delete some character is respectively to or from kernel, or increase certained
hardware support to kernel. To modify the drive compiled into kernel, user need recompile the kernel.
The following steps will describe how to generate the kener image for the MINI3250 with the Linux
develop kit in the supplied CD.
3.2.1 Generate Kernel Image
The supplied CD provide the Linux develp kit for the Mini3250, user can use it to coustomilize the
system and generate the kernel image.
1> Uncompress Linux kernel package

4.4 Update JFFS2 filesystem
When the file system in flash is damaged, file system of flash is to be updated for some reason, user
can update it by downloading the filesystem through TFTP server or mounting root file system of PC
using NFS. The hardware requemet are show as figure 4.1.
Generate JFFS2 image for 2k page size NANDFLASH
mkfs.jffs2 -r rootfs_dir -o rootfs_image.jffs2 -e 0x20000 -s 0x800 --pad=0x1e80000 -n –v
Parameter:
--pad Define the size of filesystem image. It should be block aligned and match with nand
write.jffs2
If the file system you want to download is bigger than 60MB, please refer to
the “4.4.2 Update firesystem through the NFS server” to update the file syst
em.
4.4.1 Update the JFFS2 filesystem through Network
There two way to update the file system to FLASH through network, one is through TFTP server, and
the other is through NFS.
<1> through TFTP server
The operation of downloading the JFFS2 filesystem image to Mini3250 through TFTP server is almost
the same as downloading the Linux kernel to Mini3250, after the hardware connection and
environment setting, please follow the steps to update the JFFS2 system through the TFTP server:

1> Input the follow command in the Uboot command line to download the kernel to the SDRAM
tftp 0x81000000 192.192.192.163:rootfs_image.jffs2
2> After the downlod complete,please input the follow command to burn the filesystem to the
NANDFLASH.
nand erase 5c0000 3a80000
nand write.jffs2 81000000 5c0000 1e80000
<2> through NFS server.
Update the filesystem throught the NFS require installing the NFS to the host PC.
Run following command when U-Boot startup to set U-Boot environment parameter:
setenv bootargs 'console=ttyS0,115200n81 root=/dev/nfs rw nfsroot=<nfs server
ip>:/home/nfs/nfs2440-III ip=<local ip>:<nfs server ip>:<gateway ip>:255.255.255.0::eth0:off'
After booting, system will mount nfs and enter console terminal.
After Mini3250 start up and mount the NFS, please enter the follow command to update the special
filesystem to the NANDFLASH. The default pack of Mini3250-nfs includes several kinds of GUI graph
interfaces.
flash_eraseall /dev/mtd3 //erase the filesystem partition
mount -t jffs2 /dev/mtdbloclk3 /mnt
tar xzvf mini3250-qtopia-xxxxx.tar.gz -C /mnt
//xxxxx stand for the touch or mouse. It correspond to the different GUI graph interfaces.
4.4.2 Update filesystem through MicroSD Card
Updating the filesystem image through MicroSD card, the hardware requeiament is show as figure
4.1. the UART5 is optional as the UART5 just use for printing the imformation during update process.
The follow steps will show you how to update the Uboot through MicroSD card.
1> Copy rootfs_image.jffs2 to the root directory of MicroSD card.
2> Copy loadme_fs.bin to the root directory of MicroSD card.
3> Rename rootfs_image.jffs2 to fs, and loadme_fs.bin to loadme.bin.
4> Set SERVER_N pin at high level.
5> Insert the MicroSD card to the MicroSD card slot and then power up Mini3250.
6> After the Mini3250 detects the MicroSD card and the fs in the MicroSD card, it will download
the filesystem to the sdram automatically.
7> Then system will run loadme.bin. It copies fs from sdram to NANDFLASH.
8> Remove MicroSD card and reset after nand write complete.

4.5 Customize Your Own loadme.bin
“loadme.bin” is used mainly used to update image to NANDFLASH from MicroSD card.
Now, we will tell you how to build your own loadme.bin to update your own image.
Extract u-boot-1.3.3_loadme.tar.bz2 in CD “source\u-boot-1.3.3_loadme.tar.bz2”.
tar -jvxf u-boot-1.3.3_loadme.tar.bz2 –C /home
cd /home/u-boot-1.3.3_loadme
Open configration file
vi include/configs/phy3250.h
The only parameter you need to modify is:

#define CONFIG_BOOTCOMMAND "nand erase 5c0000;nand write.jffs2 81000000 5c0000
1e80000;nboot 80100000 0 1c0000;bootm"
That is the command system will run when u-boot startup.
Before u-boot startup, the system automatically copy below files(if exist) to the specific address in
SDRAM. Meanwhile, after complete copy u-boot.bin, system burns it into NANDFLASH immediately,
so loadme.bin doesn’t need to burn u-boot.bin, it’s task is to burn uImage or fs.
Filename(MicroSD)
Copy to Addr(SDRAM)
u-boot.bin
0x83FC 0000
uImage
0x8010 0000
fs
0x8100 0000
Then we can split the CONFIG_BOOTCOMMAND string into 3 command string.
#define CONFIG_BOOTCOMMAND "nand erase 5c0000;nand write.jffs2 81000000 5c0000
1e80000;nboot 80100000 0 1c0000;bootm"
① nand erase 5c0000 # erase area from 0x5c0000 to the end of NANDFLASH
② nand write.jffs2 81000000 5c0000 1e80000 # write the image fs to NANDFLASH
③ nboot 80100000 0 1c0000;bootm # read uImage in NANDFLASH and boot
Please take attention to the command nand write.jffs2, The format is:
nand write.jffs2 81000000 5c0000 <filesize>
But how do we know the filesize? It’s defined by command mkfs.jffs2 when you create jffs2
filesystem:
./mkfs.jffs2 -r /home/nfs/nfs3250-III -o timll3250.jffs2 -e 0x20000 --pad=0x1e80000 -s 0x800 -n
The parameter “--pad” is the filesize of your jffs2 filesystem image.
Fill your own CONFIG_BOOTCOMMAND string, save the file. Then type command below.
make phy3250_config
make
mv u-boot.bin loadme.bin
