Hi Jason, I know programming over JTAG won't change tcpborphserver's device listings, but if the devices for both bitstreams/bofs were identical, then using the working bof to program and then overriting the bitstream for the FPGA would be manually doing what borph is supposed to do, right?
Hi Dave, When I try to run the .bof from the ROACH command line, it returns with "Input/Output Error". The ROACH is NFS mounted and I put the bof in the filesystem via scp. One strange thing I've noticed is that sometines mkbof creates a file that is executable and sometimes it doesn't and I have to manually set it as executable. Is this a sign that maybe it's quitting early?
