Hello Kristen, You're using rather out-of-date software there...
Could you try using casperfpga instead of corr, and upgrade your katcp to at least version 0.6.2? (Do it in a virtual environment if you don't want to clobber your install). I use this particular casperfpga commit on ROACH2, but I think more recent ones might work: https://github.com/ska-sa/casperfpga/tree/v3.1 See if that assists?
