Hi All, I'm using the UQ powerpc uclinux code on the Memec Virtex-4 FX12 Mini-Module Development Kit.
I have attached a patch with our modifications: - switch to set cache policy (OFF, WriteThru, WriteBack) - switch to enable PPC405 CPU_213 errata workaround - cosmetic update to cputable - view ccr0 register in /proc/cpu The patch is against: http://www.itee.uq.edu.au/~pml/uclinux_powerpc/linuxppc-2.4-20051021.tgz The specific modules/chips we're using have a silicon bug, See the euphemistically named "Solution 13:" http://www.xilinx.com/xlnx/xil_ans_display.jsp?iLanguageID=1&iCountryID=1&getPagePath=20658 The board boots and runs reliably with the caches OFF. WriteThru and WriteBack caching cause memory corruption and this is why we implemented the cache policy switch. regards aidan ____ :wq! -------------- next part -------------- A non-text attachment was scrubbed...
