The register values you sent a while back do not chime as anything familiar. I am out of ideas right now, except for one postulation that we have here regarding the AXI - Epiphany/FPGA interface logic. Unfortunately, we do not have the bandwidth to check that theory now, so we'll have to live with this. It may as well not be a problem with the actual Parallella boards. As for the other questions - this is really far from my territory... (what is BRAM, OCM??). I will forward you question, but it may have to wait until Tuesday (we have a long weekend for Labor Day).
