Thanks!

I have checked again the units and
- the one without Picoblade and no battery did boot from power supply only but I can not see the console without disassembly
- the first with Picoblade connector (and no battery) does not boot and the red charging indicator only flickers when powering
- finally the second unit with Picoblade connector didn't want to boot either, but after unplugging and removing the (dead) battery it did boot! And I got a boot console log. Nice :)

So this is finally a machine where I can experiment with, without relying on JTAG.

I think I just should bake an SD card through our makesd script, install a new kernel with appended DTB and try to boot with Shift+Fn.

So I finally have a setup for doing some kernel tests and development...

BR and thanks,
Nikolaus
