[U-Boot] A Problem of u-boot on TI PandaBoard porting
Hi, I encounter some problems of u-boot porting on PandaBoard.
I’m working on modifying u-boot to verify the hardware devices working well. Although there’s already a board configuration for PandaBoard (omap4_panda), I would like to create another one for my own project. The u-boot version is “U-Boot 2011.12-00046”, and I just duplicated the item of omap4_panda of “boards.cfg” and renamed it to “panda_test”, and did the same things as some u-boot porting guides which can be found on the web. Finally, after compiling, I can get ‘u-boot’, ‘u-boot.bin’, ‘u-boot.img’, ‘u-boot.lds’, ‘u-boot.map’ and ‘u-boot.srec’ in the top directory, but no MLO. There were error message prompt as below:
*u-boot/spl/u-boot-spl.lds:1: syntax error make[1]: *** [/home/qian/Desktop/u-boot/spl/u-boot-spl] Error 1 make[1]: Leaving directory `/home/qian/Desktop/u-boot/spl' make: *** [spl/u-boot-spl.bin] Error 2*
I’ve check the file ‘spl/u-boot-spl.lds’, the first line is a comment as below: *// add PandaTest Configuration*
and the rest of the file are the same as defult PandaBoard build result.
But when I just build defult "omap4_panda_config", this comment would not appear.
I guess that’s the syntax error, the *arm-none-eabi-ld* generate the ‘u-boot-spl.lds’ with a comment at first line. But it doesn’t happened when I just build u-boot for default PandaBoard. Is there any step I missed? Please let me know.
Thank you very much!
Qiao

I’ve check the file ‘spl/u-boot-spl.lds’, the first line is a comment as below: *// add PandaTest Configuration*
Change that comment to a C style one like /* ..... */ and I think the problem will go away.

But it doesn't work...because the 'spl/u-boot-spl.lds' is automatically generated while building. Even if I modify this file, it will be replaced again when I rebuild.
However, thanks for your reply.

Then dig through the build log to find where the file is generated from and modify that file...

I've run into a problem similar to this before. You probably have a C++ style comment inside your board configuration file. Change it to a C style comment instead, and the problem goes away.

Thanks for your reply, I modified the comment of include/configs/panda_test.h to C-style, and the problem solved!
However, I encountered another problem...I can build u-boot.img, u-boot.bin, u-boot.srec, but still NOT MLO

I'm wondering why these errors didn't appear while building 'u-boot.img' but appeared while building MLO? Is there any other things I need to do for SPL?
thanks!
