Ok, I saw on error of my ways, my command line was wrong. So using this:

avrdude -p x192a3 -c avr109 -b 115200 -P /dev/cu.usbserial-DA00E8PD -U flash:w:tinyg.hex

I get different results:

Programmer supports auto addr increment.

avrdude done. Thank you.

I’ve loaded the file a number of ways from github. My total file size is: 288,951 bytes
