Atmega328p bricked?

Other Hardware 3rd Party Boards

Using atmega328p with 16MHz external crystal.

I disabled the BOD in the bootloader. I gave the chip 2.5V to see what would happen. This is well below what is required to operate at this frequency.

Now I cannot program or burn a new bootloader to this device because it doesn't respond. I am using usbasp as the programmer. I have confirmed the usbasp is working by programming another chip just now.

Is this something that can damage the chip if the BOD is disabled? Is there any possible way to fix this chip?

Thanks :slight_smile:

How did you attempt to disable Brown Out Detection (BOD) ?
One way would be to hack the boards.txt file for your Arduino, change the extended fuse setting, and then proceed to burn the bootloader on to it.
It is usually quite difficult to brick these by configuration settings but, with some persistence, certainly possible. If you say what you did and with what tools, you may get a better answer.
