Hi friends,
I have this LPC1788 Embedded Artist Board, i am trying to port linux on it. As the first step to do that was to port U-boot. I found the following link on Lpcware

http://www.lpcware.com/content/project/lpc177x8x-u-boot-port/u-boot-build-procedure

This seems a good step by step tutorial for first timers. I have downloaded U-Boot version 2011-06 and the patch as directed, manage to patch it properly.

I have arm-2010q1-189-arm-uclinuxeabi-i686-pc-linux-gnu.tar.bz2 which i extracted to /opt and added a path /opt/arm-2010q1/bin as discribed in tutorial. Then the next step to add CROSS_COMPILER PATH, which is for me /opt/arm-2010q1/bin/arm-uclinuxeabi-, after completing all these, manage to config u-boot for the EA1788 board using command 'make ea1788_config'.

Then in next step donwloaded checksum and added PATH variable as suggested.
When i finally used 'make' command ....i am getting errors as follow:

/opt/arm-2010q1/bin/arm-uclinuxeabi-objcopy -O srec u-boot u-boot.srec
/opt/arm-2010q1/bin/arm-uclinuxeabi-objcopy --gap-fill=0xff -O binary u-boot u-boot.bin
./lpc17_fcg u-boot.bin u-boot-lpc.bin
make: ./lpc17_fcg: Command not found
make: *** [u-boot-lpc.bin] Error 127

please guide me...

Thank You.

Hi Friends,

I have tried the same with a different tool chain version. The end result is same, i have tried my hands with tool chain "arm-2011.03-41-arm-none-linux-gnueabi-i686-pc-libux-gnu.tar.bz2". Followed the same procedure, and same result ...haha!

Please help !!

Did you follow step 8? This downloads the lpc17_fcg application that you are missing...

BTW: Cortex-M parts are not capable of running linux. You might want to try ucLinux instead

Thanks for your reply. Yes I have thought of using ucLinux only. But got stuck in U-Boot itself.

I have completed the 8th step as follow:

•Downloaded the file from http://www.lpcware.com/content/nxpfile/lpc177x8x-checksum-insertion-program

•As such there is no readme or user guide so I have extracted the file using tar –xvjf in /opt

•It extracted two files lpc_fcg (which is an executable) and main.c

•As there is not any readme or user guide so I have just added this file PATH

•Added a PATH as ‘export PATH=$PATH:$/opt/lpc17xx_cksum_insert’

Please guide me where I did a blunder.. Tried to google about checksum value, but not much found.

Thank you.

You need to learn (quickly) about Linux shell...

The makefile is running "./lpc17_fcg". "./" means 'run from the local directory'. It does not search path or anything else.

Solution: edit the makefile to remove the "./" or install lpc17_fcg into the local directory.
