UPDI with AtmelICE, how to? about avrdude HOT 6 CLOSED

Stefan got this dual-purpose one

It's amazing: take it out of the box, turn the microswitch to UPDI, connect Gnd, Vcc and UPDI and off you go (-c serialupdi). Worth every penny. Great work by @MCUdude and @dbuchwald.

Not sure which version is the minimum one to support chips with UPDI, but can't you just get the latest version from https://packs.download.microchip.com ?

Alternatively, what would you recommend me to connect to the chip using UPDI?

The SerialUPDI programmer. Simple, fast, and reliable. Stefan got this dual-purpose one that I've designed, but you can also DIY one without too much effort.

OK, I downloaded MPLAB-X for MacOS. They don't have it natively for ARM CPUs, but the emulation works well enough, and just for a firmware upgrade, that's fine with me.

Now, I can connect successfully to my AVR16EB14:

% ./build_freebsd/src/avrdude -c atmelice_updi -p avr16eb14 -v

avrdude done.  Thank you.

but can't you just get the latest version from https://packs.download.microchip.com ?

Is the firmware in the device pack of any help to me without first installing Microchip Studio into some Windows? ;-)

I'll see how to quickly create a SerialUPDI one, thanks for the hint!

You can probably use MPLAB. Should work on a wide variety of Linux distros.

ok, good idea
