pyupdi suddenly stops working on arch linux

[wimalopaan]

I use pyupdi for years on arch linux without problems.

I don't know which update here produces this error, but actually it is broken:

@wimalopaan - full support for Dx devices was never added properly before moving over to pymcuprog. Suggest you use that package instead.

[wimalopaan]

Thank you. Found that project and it works very well!

[mraardvark]

Good to hear!

[wimalopaan]

pymcuprog seems not to work correctly for the DA. It programms only the first time the device corrctly, subsequent flashes do not overwrite existing programs. Strange ...

[wimalopaan]

To verify I would like to get this piece working again, because it was successful all the time as well with the DA devices.

[wimalopaan]

Maybe a python-3.10 issue?

[mraardvark]

are you using --erase or erasing between writes? (pymcuprog does not erase without being told to)

[wimalopaan]

Ok, thanks.
I switch to the pre-release with the --erase flag.
