More broadly speaking, has anyone ever used the DDR powerPC interface on ROACH2? Is it actually know to work with code as-provided in the mlib_devel / katcp repos? Franco -- perhaps this project -- https://github.com/argonnexraydetector/RoachFirmPy -- which I found linked on the DDR page of the CASPER wiki, might be interesting to you.
