This is C version of UPDI interface achievement, you could refer to the Python version:

https://github.com/mraardvark/pyupdi.git

My purpose is you could use UPDI to flash the new TinyAVR at any enviroment like Computer / MCU Embedded system, just transplant the code the there.

I used other vendor library, thanks:

Usage: Simple command line interface for UPDI programming:

or: cupdi [options] [[--] args]
or: Erase chip: cupdi -c COM2 -d tiny817 -e
or: Flash hex file: cupdi -c COM2 -d tiny817 -f c:/817.hex

A brief description of what the program does and how it works.

-h, --help            show this help message and exit

Basic options

-d, --device=<str>    Target device
-c, --comport=<str>   Com port to use (Windows: COMx | *nix: /dev/ttyX) (Linux platform not finished yet)
-b, --baudrate=<int>  Baud rate, default=115200
-f, --file=<str>      Intel HEX file: to program, save or verification 
-u, --unlock          Perform a chip unlock (implied with --unlock)
-e, --erase           Perform a chip erase (implied with --flash)
-p, --program         Program Intel HEX file to flash
-k, --check           Compare Intel HEX file with flash content
-s, --save            Save flash to a Intel HEX file
-u, --fuses=<str>     Fuse to set (syntax: fuse_nr:0xvalue)
-r, --read=<str>      Direct read from memory [addr];[n]
-w, --write=<str>     Direct write to memory [addr];[dat0];[dat1];[dat2]...
-v, --verbose=<int>   Set verbose mode (SILENCE|UPDI|NVM|APP|LINK|PHY|SER): [0~6], default 0, suggest 2 for status information
-t, --test            Test UPDI device

Example:

Write memory:
    cupdi.exe -c COM7 -d tiny817 -v 2 -u -w 3f00;01;02;03;04;05

Read memory:
    cupdi.exe -c COM7 -d tiny817 -v 2 -u -r 3f00;5

Erase Flash:
    cupdi.exe -c COM7 -d tiny817 -v 2 -e

Program:
    cupdi.exe -c COM7 -d tiny817 -v 2 -f tiny817.hex    or
    cupdi.exe -c COM7 -d tiny817 -v 2 -p -f tiny817.hex     (if no other operation for file, default programming)

Verify Flash:
    cupdi.exe -c COM7 -d tiny817 -v 2 -k -f tiny817.hex

Save Flash content:
    cupdi.exe -c COM7 -d tiny817 -v 2 -s -f tiny817.hex     (The content will save to tiny817.hex.out)

Building

bash autogen.sh
bash configure
make

Binary will be generated in the repo root, execute with ./cupdi
