I am now getting these errors. It's the software, not boards as I have two known-good boards sitting on my desk right now, unless both blew at same time. It started happening uploading the ESP8266 code below... now any sketch causes this or similar AVR errors.
I tried restarting the IDE to no avail. I changed USB (serial) ports as well, and of course switched out boards. See verbose error below.
avrdude: stk500_paged_load(): (a) protocol error, expect=0x10, resp=0x00
