Did I fry 2 arduino uno boards ?? :(

Post by nrdufour »

Hello,

I just got a bunch of arduino uno boards from adafruit to replace one that seemed fried I was using in my IoT printer.

It seems one is now having the same issue:
- the onboard LED (pin 13) is constantly on.
- whatever I send to the board, I see the RX led blinking but nothing else and showing this:

Code: Select all

         Using Port                    : /dev/tty.usbmodemfd131
         Using Programmer              : arduino
         Overriding Baud Rate          : 115200
avrdude: Send: 0 [30]   [20] 
avrdude: Send: 0 [30]   [20] 
avrdude: Send: 0 [30]   [20] 
avrdude: ser_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding
- pushing the reset button doesn't do anything

Is there a way to check if the board is still "alive"?
Any suggestion?

Thank you,

Nicolas

Sounds like the 32U4 USB/Serial part is working. But the 328P is stuck on something. You could try swapping 328 chips with a known good UNO.

Not sure to understand here. Swapping what?

It seems this tutorial to be a good start: http://www.ladyada.net/library/arduino/upgrade.html

Thanks for the tip :)

I swapped the chip from one board to the other and the board is now working the right way.
So I guess I fried those 2 328p but not their respective boards.

Thank you for the help!

Good work! Replacement chips are available to get your board back up and running.
