TinyG Update failure | Synthetos Forum

Oops, I seem to have bricked my TinyG

I downloaded the EDGE FW

I am doing this from Linux, I have avrdude

avrdude version 5.11.1, URL: <http://savannah.nongnu.org/projects/avrdude/>

I hit reset on TinyG and started avrdude

> avrdude -p x192a3 -P /dev/ttyUSB0 -c avr109 -b 115200 -U flash:w:tinyg-edge-412.01.hex

Seemed like it was initiating OK, but then aborted.

TinyG flashing led now, as if in constant reboot.
Tried long power off-power on, no difference.

Unless I find a fix soon, it will be in this afternoon's mail for a reprogramming (might as well load EDGE)

Update: I tried reloading tinyg-master-380.08.hex, no joy.
