[microblaze-uclinux] XUPV2P Board with 512MB DIMM

[reichardt@xxxxxxxxxxxxxxxxxxxx]

Hi folks,
I just joined the uClinux project and have a XUPV2P board available which is 
equipped with a 512MB DIMM memory.
Normally all Xilinx reference designs use the 256MB DIMM modules. Also the 
download project from the xilinx homepage uses 256MB DDR.

With other design implementations I had to learn that the 512MB opb_ddr interface 
has significant timing problems if I use ISE 7.1i. I was told that those problems are 
solved by using ISE 8.1 or 2.

So my questions:
- Did anyone use the XUPV2P with 512MB DDR
- Do you use ISE7.1 or ISE8.x
- If you use the 512MB DDR, did you have to recompile the image.bin because the 
opb_ddr IP names and so the information in the xparameters.h are different? 

Thanks in advance

Juergen
