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
