Hello,
Does anyone else have problems with MPMC2 + flash bootloader in EDK v9?
I started a design on the FX12 mini-module using the ethernet echo server reference design from Avnet. I then added a flash bootloader functionality by taking the flash controller from another Avnet reference design. Unfortunately this combination doesn't work for some reason.
A webcase with Xilinx (opened for one month) did not offer a solution for this issue. Avnet however was quicker to respond, they acknowledged the problem, quoting : "The bootloader design in EDK
9.1.02 using the MPMC2 core has some issues.". They sent me a modified echo server design using the PLB DDR controller instead of the MPMC2 and it works. Unfortunately the perfomance suffers.I have yet to understand what the particular issue is. It is not clear if this is a flaw intrinsic to MPMC2 or if it's related to the FX12 mini-module. I'd like to know about others experiences with the MPCM2 and/or mini-module.
Thanks!
