yes I modified the script I use for my TS10, which does work to backup and to load hex files:
pymcuprog read -m all -f ~/Desktop/ts10.hex -t uart -u /dev/tty.wchusbserial1430 -d attiny1616
I tried to backup my D3AA with this script:
pymcuprog read -m all -f ~/Desktop/D3AA.hex -t uart -u /dev/tty.wchusbserial1430 -d avr32dd20
but it does not work… I get a long series of comments from the Terminal window:
Jonathans-iMac:~ jonathan$ pymcuprog read -m all -f ~/Desktop/D3AA.hex -t uart -u /dev/tty.wchusbserial1430 -d avr32dd20
