Re: [microblaze-uclinux] HELP ME¡¡¡

Hi John,
I think this is a bug in the ucfront-ld tools, in the latest uClinux-dist. Please try the attached patch and see if it helps. You will need to do the following from your uclinux-dist directory: 

$ patch -p0 < ucfront-ld.patch
$ make -C tools/ucfront clean
$ make
Please let me know if this helps, I have submitted the patch to the uclinux-dist maintainers as well. 

Regards,

John
