During the upload of a sketch I get the following error:
avrdude: verification error, first mismatch at byte 0x0042 0x15 != 0x17 avrdude: verification error; content mismatch avrdude: verification error; content mismatch
This happens with all sketches except the example "Blink". Blink is currently running en seems to do fine. Any other sketch i try to upload fails.
This is the board information:
BN: Arduino/Genuino Uno VID: 2341 PID: 0043 SN: 75335313537351412170
I use Arduino IDE 1.8.5 with the following settings:
board: arduino/genuino uno
programmer: AVRISP mkII
Anyone familier with this problem? Any possible solutions?
I am trying reburn the bootloader with an cheap USBASP from dealextreme but without success so far.
