Do you have a non-tristate hal pin driving the has_bit pin?
That would prevent you from setting it by hand
resetting works for me:
pcw@pcw-G41M-Combo:~/linuxcnc/configs$ halcmd setp
hm2_7i76e.0.watchdog.timeout_ns 100
hm2/hm2_7i76e.0: Watchdog timeout (100 ns) is dangerously short compared to
hm2_write() period (1000000 ns)
hm2/hm2_7i76e.0: Watchdog has bit! (set the .has-bit pin to False to resume)
hm2/hm2_7i76e.0: trying to recover from IO error or Watchdog bite
pcw@pcw-G41M-Combo:~/linuxcnc/configs$ halcmd setp
hm2_7i76e.0.watchdog.timeout_ns 10000000
pcw@pcw-G41M-Combo:~/linuxcnc/configs$ halcmd setp hm2_7i76e.0.watchdog.has_bit
false
hm2/hm2_7i76e.0: error recover successful!
