Hi, For some unknown reason, boffiles I generate with my toolflow cause ROACH 2's to freeze up after a few minutes (I think related to I/O to software registers and shared BRAMs rather than any specific amount of time). I don't know of any changes I made to my toolflow since the last time I compiled working boffiles. Previously working boffiles still work, but recompiled designs do not work. The symptom is that the python katcp client stops responding. SSHing to the ROACH and running ps shows that tcpborphserver3 is no longer running. It finally occurred to me to check dmesg, and on all crashed ROACHs, I see this in the demsg:
...

Any ideas where to look for this problem? Thanks, Glenn
