Re: Introducing SerialUPDI programmer

[Dawid Buchwald]

I might be wrong, but based on the information found here: 
https://github.com/SpenceKonde/AVR-Guidance/blob/master/UPDI/jtag2updi.md there 
are actually quite a lot of issues with jtag2updi implementation in AVRDUDE, 
and the SerialUPDI utility provided by Microchip seems to be better option.

The idea is to implement direct support for simple USB->UART based UPDI 
programmers without the need to install additional tools like pymcuprog.

Best regards,
Dawid

Hmm:

"pymcuprog is a Python utility for programming various Microchip MCU
devices using Microchip CMSIS-DAP based debuggers"

If it handles the CMSIS-DAP based debuggers, what's different from the
UPDI support that is present in the AVRDUDE SVN?
