Hi,
I am using a Sparkfun Redboard Qwiic, and whenever I upload a sketch, this error shows up:
avrdude: stk500_paged_load(): (a) protocol error, expect=0x10, resp=0x00
avrdude: stk500_cmd(): programmer is out of sync
avr_read(): error reading address 0x0000
read operation not supported for memory “flash”
avrdude: failed to read all of flash memory, rc=-2
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
It seems to work fine afterwards. I can open the serial monitor and it shows me the data that I want to see. Nevertheless, I am wondering, if there is a chance to solve this problem, as I am using this for a class I am teaching. With some microcontrollers this error shows up, with some it does not. I did not figure out yet, if it was a windows or a mac problem.
Thanks for the help.
