Hi Jon,
If you post where you are and what is incorrect/needs work then maybe some others on the list who know how to port u-boot SPL may be able to help.
Also, it would be nice if you documented the steps you took to fix the toolchain symlink and also the line removed from mtd-utils. That way, others can manually do the fix-ups and possibly someone may find time to turn it into a patch that can be applied against LTIB CVS. 

Regards, Stuart

Hi Stuart,

You want to push that patch in? I somehow missed the custom toolchain option, 
but the custom toolchain arguments options is there. Must have been one of 
those days. I'll check the others to see if any more are missing that.

After fixing the relative symlink issue up manually I rebuilt
everything using Linaro 4.6.1 gcc. Everything built except for
mtd-utils. The source for mtd-utils needs a line deleted in order to
build.

I can't test since I don't have my system in a running state. I'm
still messing around with porting uboot up to the current revision.
But this gets me around the kernel complaining that the C compiler has
known bugs that will make the kernel fail.

Any help with the u-boot port would be appreciated. The conversion to
u-boot SPL support is rather complicated.  I have already ported the
kernel support up to the current version. After I get u-boot working I
will start submitting this code to mainline.



It is copying a relative symlink:
address@hidden:/home/apps/ltib$ ls
/usr/lib/gcc/arm-linux-gnueabi/4.6.1/libgcc_s* -l
-rw-r--r-- 1 root root 135 2011-09-29 02:56
/usr/lib/gcc/arm-linux-gnueabi/4.6.1/libgcc_s.so
lrwxrwxrwx 1 root root  47 2011-09-29 03:03
/usr/lib/gcc/arm-linux-gnueabi/4.6.1/libgcc_s.so.1 ->
../../../../arm-linux-gnueabi/lib/libgcc_s.so.1

Which doesn't work after it is copied.

Hi Jon,

This stuff is processed in config/userspace/toolchain.lkc which should
be included in the BSP's config/platform/_target_/main.lkc file.

Maybe whoever made this platform forgot to add it into the list of
toolchains for that platform?  Which platform do you have selected?

Embedded Artists board with the NXP LPC3131

The EA config files are not using the support in config/userspace


Not sure why they missed that in their BSP config.  If it's the one I
think you mean, you could try adding this patch:
