Hi,
I can build my program in Arduino and platform.io but I can't upload it on my Mac. The hardware shouldn't be a problem because it works on my windows computer but not my Mac. I can't even upload an empty sketch. Error message on platform.io:
avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x00
avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x00
avrdude: stk500_initialize(): (a) protocol error, expect=0x14, resp=0xe0
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
avrdude done. Thank you.
