I run self test until it stalled. It happens in while loop on host side.
One of the cores (first time it was 14, second time 13, third time 15)
stalls somewhere before do while loop. I checked shared DRAM, 16 is written
in memory for both start arrays for that specific core so conditions in
while loops are true but it never reaches BF_crypt() call nor resetting
start flags. I also added writing different number instead of result after
every line in main on Epiphany side - core that stalls never reached first
write that was before do while loop. Only zeroes were in memory for result
and core_done flag for that core. All the other cores except the one that
stalls work correct. And it happens only in first cryp_all call. So far it
never happened in the middle of computation. It seems as that one core
never starts computation.
