Hi all!

Today the PCBs have arrived and I spent some tiem building the first
prototype.  Soldering after a long time was quite fun but worked great.

However, I got stuck for way too long due to two pin-out problems:
* the voltage regulator pinout is completely mixed up
* the reset switch pinout is wrong and causes the device to be in nRESET
  all the time

I've now applied some re-work and the CPU seems running. However, due to
some unknown (probably USB pull-up related) problem, I cannot see it
enumerate on USB yet.

Will keep you posted about my further progress.

I've created tickets for the bugs in our trac
(http://bb.osmocom.org/trac/query)

Regards,
	Harald
