Was that the expected response? "x00x"
Also, the "Invalid argument" seems to happen on write too, and it's
different from the "file not found" error...

Hey guys,
I'm trying to read and write to a ROACH1 using the BORPH
filesystem. I followed the tutorial at
https://safe.nrao.edu/wiki/pub/CICADA/FlashLights/BorphGettingStart.pdf,
but got somewhat different results
root@roach:/boffiles# ./asmls_roach0_2013_Mar_15_1123.bof

root@roach:/proc/618/hw/ioreg# cat spec_count
cat: spec_count: Invalid argument
root@roach:/proc/618/hw/ioreg# cat acc_always_valid
cat: acc_always_valid: Invalid argument
root@roach:/proc/618/hw/ioreg#
spec_count is a output reg, while acc_always_valid is an input reg.
Anyone know what I'm doing wrong? Thanks!
