I start to use Atmel-ICE and I get an error: "Read voltage -5,3v is outside selected devices voltage" simple error so I check my pins for proper connection -> all good. By schematic:
But error remain. So I figured there is some troubles this my circuit board. Power switch can be appear on GND-RESET-VCC connections. My circuit:
All other pins (MOSI, MISO SCK, Chip VCC, Chip GND) have no any circuit connections between each other.
I tested Atmel_ICE with AtmelStudio7.0 on my Arduino-UNO R3...all working good and I can read device and re-wrire program. But on my other boards (my own desine) error remain. I look into Arduino-UNO R3 electric schematics do not have any such circuits line on img. Probably img GND-RESET-VCC schematics musk be changed for Atmel-ICE. Any suggestions??)
