Follow-up Comment #8, bug #61624 (project avrdude): > First of all, thank you A LOT for your time and I'm really sorry it didn't work for you. Unfortunately, I don't own any other UPDI based MCUs, and there are apparently three different programming models for those, so I need to do some shopping today.
Well, I'm just happy I can help out with the development! I also own a bunch of tiny0/1 boards as well, so I can also help you out testing these when the time is ready. After further investigation, it looks reading flash does work, since the correct content are being received in verbose mode. However, Avrdude don't pick it up. When running the following command: $ /Users/hans/Downloads/SVN/avrdude/avrdude -C/Users/hans/Documents/Arduino/hardware/MegaCoreX/megaavr/avrdude.conf -vvv -patmega4809 -cserialupdi -P /dev/cu.usbserial-1410 -b230400 -Uflash:r:dump.hex:i I can see that the actual flash content data is received (matched the loaded hex file), but Avrdude concludes that flash is empty, and dump.hex only contains :00000001FF. Here is a "compressed" output of the flash read command: $ /Users/hans/Downloads/SVN/avrdude/avrdude -C/Users/hans/Documents/Arduino/hardware/MegaCoreX/megaavr/avrdude.conf -vvv -patmega4809 -cserialupdi -P /dev/cu.usbserial-1410 -b230400 -Uflash:r:dump.hex:i ... avrdude: Version 6.3-20211205 Copyright (c) 2000-2005 Brian Dean, http://www.bdmicro.com/ Copyright (c) 2007-2014 Joerg Wunsch ...
