I'm beginning development with a Xilinx PPC/FPGA. I've now gotten my feet wet and have a few successes and a few head scratches. I have a Xilinx ML403 dev board. I ran the Monta-Vista Linux 2.4 demo. good. Now for my own attempt. (Please reply if anything I'm doing is incorrect) I found a pre-built toolchain for my i686 Debian host with gcc-4.1.1 + glibc6. I downloaded kernel 2.6.23-rc3 after reading several posts on this list about the ML403 and drivers in this kernel version. Problem 1: The kernel did not have the correct memory information. I noticed in 'embed_config.c' that the board params are hard coded, however my kernel was not linking with that version of embed_config(). It was linking with embed_config() in 'misc-embedded.c' Did I miss a config parameter in the kernel config?? My kernel now boots and mounts the MontaVista rootfs on the SystemACE Flash!!! :) Problem 2: Build my own rootfs. If I try to build my own programs (busybox and bash at this point) with shared libc using the same glibc from my toolchain, I get an "Illegal instruction" error. Is my glibc not compatible with my Xilinx PPC 405?? If I try to build a rootfs with debian ppc packages I have the same "Illegal instruction" error. Question 1: Do I need a special glibc for the Xilinx PPC 405???? Does a normal PPC glibc have more "advanced" instructions compiled in that will not work on a Xilinx PPC 405?? Question 2: Is it true that the xparameters.h file produced by Xilinx EDK is not compatible with the current 2.6.23 kernel?? It appears that if I change params (addresses or IRQ's) in my Xilinx EDK I need to hand edit the xparameters.h in the kernel source tree. True? BTW: My Xilinx EDK is version 9.1i with full ISE 9.1i. I'm looking forward to helping the Linux on Xilinx PPC effort!! Woody.
