Hello All,

I'm trying to use ethernet FCC on an board using MPC8541E, and I'm having some problems. First of all, current code on u-boot has a "known issue" that prevents it from working, which makes me wonder if someone out there has ever used this code. You can find further details at http://ozlabs.org/pipermail/linuxppc-embedded/2004-November/016050.html but, basically, there was a parameter set to use a reserved area in DPRAM. I changed CPM_FCC_SPECIAL_BASE fro 0xb000 to 0x9000 on include/asm-ppc/cpm_85xx.h. However, even with this change, I can only do tftp of small files (a 1 to 3 tftp packets), otherwise u-boot hangs. If I stop it afterward with a debugger, the CPU is executing in "no man's land". My main question is: has anyone ever used FCC as ethernet on u-boot for mpc85xx, and with what success?

Thanks and Best Regards, Nuno
