Hi, Is there a way to hack the MPMC into not using the MCB (but the softcore MIG) on Spartan-6? The MPMC datasheet says no, but since the MIG source code is mostly behavioral (iirc), maybe there is a way around this. I have a board with DDR SDRAM and a pinout that is not compatible with the MCB, and my custom softcore platform (that is not using the MCB) randomly crashes when running complex software (Linux systems etc.). I'm suspecting a DRAM problem. It is stable on Virtex-4, tested on the ML401 board. I would like to test my custom board with Microblaze in order to put potential PCB or signal integrity problems out of the equation. Thanks S.
