to those of you who have ported uboot to the Virtex II PRO P4/7, i have a nice, simple, straightforward question for you... :*)
what is your boot strategy?
do you load a minimal FPGA/uboot image (from flash) into the internal RAM (~80KBytes big) and then in turn download the OS and application code? OR do you have a very very simple FPGA/bootloader image which in turn loads uboot into EXTERNAL RAM and then uboot loads the OS and application code? OR yet some other way?
related to option 1 above... does uboot for the the Virtex II PRO P4/7 fit nicely into the 80KB?
thanks for any insight.

If memory serves me correctly, I was able to get PPCBoot 2.0.0 running on that very board with relatively little effort. I based it on the ML2 support that was already in there. It was just a proof of concept exercise so I didn't do anything with the flash or Ethernet (on the P160 comm module). Basically got it up to the command prompt and that was that.
I was also able to get PPCBoot 2.0.0 (yes, I know :-) running on our own V2Pro board (http://www.amirix.com/images/PCIPlatform.pdf) with moderate effort.

hi,
has anyone done any u-boot porting work for the Memec Virtex-II Pro P4/7-FG456 evaluation board?
as you can see from the link below this is a development board which has the Virtex-II Pro (w/ single 405GP core) along with SDRAM, NV stroage via compact flash, and so forth.

we are considering using this board as an R&D platfrom for an upcoming project.
thanks!
