Hi Katja,

Hope you are feeling well by now.

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).

Yaniv.
