I have searched and finally found my Letux 400 devices... Two are early samples
and they have a 4 pin connector. Yes, Molex picoblade fits. And interestingly
I must have built a Max232 adapter years ago and did forget.

Unfortunately the machines with connector don't boot. And the one which boots
has no connector.

How did you set up JTAG? Many years ago I developed an adapter to connect
through a ribbon cable (after disassembling the '400) and use an OpenMoko
Debug Board. But at that time there was no OpenOCD software for such a
setup so I had to stop experiments.

Yes, great! I have pulled you patches to the letux repo (and renamed them a little):

https://git.goldelico.com/?p=letux-kernel.git;a=heads

What I have not yet done is rearranging and squashing anything.

Anyways the key question for me is what to do next to help testing...

BR and thanks,
Nikolaus
