This watchdog takes a look at GPIO pin 11, which needs to be set as an output pin and needs to be set high. If it is not, this signals that the battery has a low voltage. And the unit powers off. I have no idea where this is clobbered so early for the Bitsy arch, but I just successfully booted the cerf1110 after changing the lines: g->gpdr =3D EnableRS232In | EnableRS232Out | CFReset; g->gpsr =3D EnableRS232In | EnableRS232Out; to g->gpdr =3D EnableRS232In | EnableRS232Out | CFReset | (1<<11); g->gpsr =3D EnableRS232In | EnableRS232Out | (1<<11); So it now probes all the devices and turns my screen white ;). The cerf1110 port from Inferno, I should qualify (if that wasn't immediately obvious). What now? I'm going to ditch most of bitsy's code and start (mostly) fresh.=20 Whoo! --Devon --yh423QPMiEk4ZruG Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQFCW9i+Skf3jVXOdl0RAkGcAJwOEv/8xoaazXRs4Pbdc8XVFGzalACggFm3 Q2JyIqzgzUXz+d5kJf6fLGE= =p1Y8 -----END PGP SIGNATURE----- --yh423QPMiEk4ZruG--
