I try to program atmega32u4 on mangoh green board with AVRISP MKII.
Whan I connected, programmer start to blink orange led, it means “Reversed target cable connection, or not correct pull-up on the reset line”.
In Atmel Studio 7 I can read voltage, but read signature fail. May be I need to drive some jumper?
Or in schematic pdf (“schematic_mangOH_Green_DV4_2500905.pdf”) on the last page is talking about
some resistors on ICSP header. What am I supposed to do with them?
Is there anyone who uses the ICSP connector?
