Good Morning to everyone,
I am an engineering student, new to Arduino programming, and in the last days I've been having problems with uploading sketched to the arduino nano that I have always worked with.
When I plug it in it looks fine, leds light up as usual, but whenever I try to upload a sketch I get the following error:
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x9c
I have seen many posts about it, but none of the solutions given was working fine for me. Serial communication is working, the port and the bootloader are the right ones, I checked everything, but still when I upload a sketch the RX led blinks 3 times, then stops, and blinks 1 time for each new attempt.
Moreover I have tried to re-burn the bootloader but it's giving problems with the wiring.
Do you have any solutions? Or do you think that I burned it somehow?
Thank you very much!
