I’ve bought my seeeduino couple weeks ago and absolutely loved its innovations and slick design, but it worked for 7 days only!!! Now when I try to upload a sketch it returns error:
avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x80
avrdude: failed to write flash memory, rc=-4
avrdude: stk500_recv(): programmer is not responding
TX and RX LEDs blinking for some time and then stop.
Seeeduino was connected to very simple board with 16 LEDs and two shift registers. All LEDs had 1k resistors and were powered from 5v pin. Seeeduino had a 9v battery supply, and was switched to 5v mode. It worked in such configuration for about a day and then stopped. I’m sure it isn’t my fault.
Would you please tell me what that error message means? And how to fix it if possible?
