a public thank you to everyone who has

we've been getting a steady stream of a
couple a day, and we've had over 250 since
the patch tools were created.

So, it turns out that the SIMpad has a watchdog. 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 = EnableRS232In | EnableRS232Out | CFReset;
g->gpsr = EnableRS232In | EnableRS232Out;
to
g->gpdr = EnableRS232In | EnableRS232Out | CFReset | (1<<11);
g->gpsr = 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.
Whoo!
