I have a problem with my Arduino Uno board. It's not mounting in my Linux machine, but its power is on and the LED light is glowing. It was working before. After I tested buttons with an 12 V external supply, I am facing this scenario.
I tried lsusb
and I checked /dev/ ports
. Also, I couldn't find `ttyACM. I tried with another Arduino board and it's working. I think the board is gone, and I need help to fix this problem.
I thought it was a bootloader problem, and I got a new ATmega328P chip board. It is getting power on and the LED is blinking, but the port is not mounted. I tried with lsusb
and also ls /dev/ttyACM*
with no result.
