Hey Tsvetan,
A customer has pointed out some problems with the P2106 schematic. It seems the button connection is not really on pin 16 of the LPC2106, but is instead connected to pin PO.15 (pin 45 on the schematic). I’ve verified this mis-connect as well. Could you check with your engineers to see what other differences there are between the schematic and the P2106 board?
Thanks!
