Summary: [Feature request] Serial/UART UPDI programmers Project: AVR Downloader/UploaDEr Submitted by: None Submitted on: Mon 06 Dec 2021 11:57:08 AM UTC Category: None Severity: 3 - Normal Priority: 5 - Normal Item Group: None Status: None Privacy: Public Assigned to: None Originator Name: Hans Originator Email: hansib...@me.com Open/Closed: Open Release: SVN snapshot Discussion Lock: Any Programmer hardware: serialupdi Device type: _______________________________________________________ Details: I know this is a lot to ask, and I don't expect anyone to jump onto this immediately because one guy would find this incredibly useful. Avrdude now supports most UPDI compatible programming hardware, but the "last" thing it lacks is the ability to program UPDI compatible AVRs using a serial port and a resistor like used in pyupdi and pymcuprog. https://github.com/mraardvark/pyupdi https://github.com/microchip-pic-avr-tools/pymcuprog A "Serial UPDI" programmer is pretty much the simplest programmer you can make, and by controlling the DTR/RTS line while the UPDI communication is active, one could easily create a neat programmer you can use for both programming and serial debugging. I'm sure this feature would make UPDI compatible AVRs even more appealing, especially since Avrdude is a binary file that "just works" on all platforms, while a Python package isn't as simple. _______________________________________________________ Reply to this item at: <https://savannah.nongnu.org/bugs/?61624> _______________________________________________ Message sent via Savannah https://savannah.nongnu.org/
