Python cross platform programmer and debugger for Microchip CMSIS interfaces.

Processor support is limited and various components are marked with “alpha” support at this time.

It can work with boards with built-in interfaces or the SNAP and PICKIT 4 interfaces updated with new firmware and switched into AVR mode (untested).

Connect a MCHP SNAP in CMSIS mode to the Seeduino Xiao and see if it functions.

Python 3 is a requirement and the tool is installed using pip.

apt install python3 python3-pip
rehash
pip3 install pymcuprog

Listing the devices directory will inform you of the supported controllers.

ls /usr/local/lib/python3.7/dist-packages/pymcuprog/deviceinfo/devices/

The help file mentions getting software packs for more options but visiting the pack site offers nothing useful.

Supported interface but unsupported microcontroller (ATMega328PB).

This is a virtual console port (AKA USB software modem).

Unsupported interface, microcontroller (PIC16F18855) support unknown.

This is mass storage device and no idea if the firmware can be altered othewise.
