I was looking at some things today, and I found this site, which has some files for Jornada 720.

In it, I found a directory called flashboard.
I honestly don't know what it is, but some of you might find it useful.

Lots of Linux stuff till 2008 here:

Great find!

Looks like they are for the JLime project

And here in particular there are lots of hardware info and documentations. Maybe useful for the incubating projects (debian/retrofit)?

These flashboard files are for the flashboard PCB.
I already made a few of those, but for initial flashing you need a device that can program the flash chips or the JTAG interface of the SA1110.
I try to trace these pads if i get a faulty mainboard, because i need to desolder the CPU.

Thanks for the explanation.

I have a Japanese ARM book that had some things about JTAG. I'll look if it can help. I think it has a really detailed manual of the StrongARM chip in a PDF...
