#
# Fun fact: a direct flashmem-lockflash-pld reconfigure sequence leaves
# the FPGA in a weird state from which it can't boot out of standby, neither
# via JTAG (pld load ...) or by pressing the middle button.
#
# The only thing that seems to help is to run "detectflash" after the locking.
# (Tried "peek", "usleep", "pld readreg", ... without success.)

# FIXME: the exit code of "jtag" doesn't indicate whether the session was
# successful.
