Linux on Virtex4

I am also operating Linux by Avnet V4FX12MM of a MPMC2+GSRD design.
However, V4FX and a PHY chips get very hot, and this design may
malfunction and may output oops.
Therefore, like an attached photo, my V4FX12MM applies a heat sink
and FAN, and is operating them.

Is it stabilizing and operating by your design?

> Hi Rick,
> I saw on linuxppc-embedded at that you are trying to port 
(or better you did) monta vista linux to Avnet's V4FX Mini-Module. I 
will try to deal with the same thing. My design is basically the same: 
all features of MM incorporated in CoreConnect style architecture. I 
also tried with Multi Port Memory Controller (MPMC2) and ported (memory 
works, but for LAN I still need phy datasheet) the Gigabit System 
Reference Design (GSRD2) to Mini-Module.

using two PLBs (data and instruction separated). This way you might 
solve the CPU cache errata. The problem with MPMC2 is that it consumes A 
LOT of BRAM and logic. I tried to build a full featured system, but 
V4FX12 lacks logic for the purpose.
