Stuck in boot loader when doing firmware upgrade?

Attempted to upgrade firmware on my tinyg. This is a new setup for an OX CNC I am building. Chilipeppr on first connect suggested the firmware upgrade. I downloaded the tinyg updater, but, received an “verification error”.

I then followed the tutorial to do the upgrade via command line on my MAC and received the following error:

./avrdude -p x192a3 -C ../etc/avrdude.conf -c avr109 -b 115200 -P /dev/cu.usbserial-DA00W2V6 -U flash:w:tinyg-master-440.17.hex

avrdude done. Thank you.

Note that during the write, I had a endless amount of ” ***failed;” scroll by.

Now the board seems to be stuck in the boot loader mode. The spin led flashes red the entire time the board is powered on.

Any thoughts on how to proceed?

Thank you in advance!
