Need help, cannot seem to reflash bricked board.
« on: Sun, 30 April 2017, 20:18:00 »
I have a ps2AVRGB board that I built and decided to put QMK on. Flashing the QMK firmware did not go well.

After which the board was totally unresponsive and when reconnected doesn't show up as anything. No big deal, it has an SPI exposed as I have done this before I just wired the SPI to a raspberry pi to flash it back to ps2avrgb till I sort out what went wrong with QMK. Unfortunately AVRDUDE reports that it cannot talk to the chip. The chip on the board is an ATMega32A which should just be an ATMega32 signature. However AVRDUDE is unable to see or recognize the signature.

I may try to set up an Arduino as a straight SPI programmer and program from the mac but thought someone here might have sone insight.

According to this post they have the same signature so they are indeed the same to avrdude.

The one thing you could try is to swap MISO and MOSI, sometimes they are labelled wrong.
