Hello, I have read a lot of topic about sync errors (stk500). But no one helps me to find out about my problem.
UPDATE : I have changed with a working ATmega16u, and I still have got the stk500, so the problem could come from the ATmega32u, could not ?
This is the situation : - Arduino Nano (ATmega328P U & ATmega16u2) - Board and port correctly selected - IDE is up to date - Nothing connected - L LED is always on (never blinking, even after plug/unplug USB) - Driver seems correctly installed. (Device Manager-> Port -> Arduino Uno (COM5)) - Driver configuration is identical to an other arduino driver (which works with another arduino uno (older)) - Uploading log :
avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0xc6
I thought that it was a bootloader problem, so I did that : https://www.youtube.com/watch?v=UQk8oLreP8E But nothing has changed.
The problem does not come from the cable, my computer, ... Because I have another Arduino Uno (older) that works perfectly.
I really read a lot of about this kind of problems on the forum and I'm not here to write redundant topics.
Tell me if you need more informations. Thank you in advance
