Virtex-4 FX12 Mini-Module support

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

Hi Aidan,

 

After I searched the web I found out that you have sucesfully run the
uClinux 2.4 on Virtex-4 MiniModule. I have developed a GSRD2 design on which
I would like to run uClinux. There are two problems:

I am new to linux

I don't know where to start

I would appreciate if you could share your design with me and give me help
with running it on my design.

 

Cheers,
