Hi All, I designed a PCB based on the Mega 2560 schematic, and I'm unable to bootload it. I've made boards previously based on the Duemilanove , and I've never had a problem. One issue I noticed; the programming headers on the schematic for the 2560 have the MISO and SCK lines reversed with respect…

Mega 2560 Schematic programming header pinout question

I just looked at MEGA2560 vs Uno R3 schematic - the ICSP headers look the same to me:

MISO - +5V
SCK - MOSI
Reset - Gnd
