There should be sufficient options to the compiler that wouldn't require rebuilding. I suspect telling it to use a 603 core with 405 instruction scheduling will make it work. Actually, just a 603 will make it work, the additional scheduling hints may improve performance. The bigger challenge is the kernel mofication necessary to properly context switch the FPU on this part. > -- the #if 0 portion was what was already in head_4xx.S (w/o the if 0) > but didn't work. the #else case was taken from head.S and seemed to > work. You are working with a really old kernel. Find a newer one. I would recommend the 2_4_devel tree for what you are doing. -- Dan ** Sent via the linuxppc-embedded mail list.
