4. Re-flashing the bootloader multiple times (avrisp)
I have a new ATmega328P that won't respond to pulling the RESET pin low.
Are you using the ArduinoIDE to install the bootloader?
Which seems odd since a reset is required for this to happen
The bootloader does flash the LED upon power up, though
QuoteThe bootloader does flash the LED upon power up, thoughThis is odd too. Assuming that you're using Optiboot, the bootloader should not run, and it should NOT flash the LED, on powerup. This is the "Adaboot fast start mod" that starts the sketch immediately on powerup, and only attempts uploading based on an "external reset."Any chance that this somehow contains the wrong bootloader?
The problem is that it does not restart after a reset.
On this solemn day we mourn the passing of a processor that never saw its full potential. Struck down before it even had a chance to run Blink-Without-Delay. We hope you find solace in Silicon Heaven.
