SerialUPDI upload fails with huge python error?

[gordonthree]

Working on a avr128da28 under Arduino 1.8.19 on Fedora, get this error trying to do UPDI upload of a sketch

UPDI does work to upload the bootloader, but my five serial adapters are all busy for diagnostics, so I need to stick with UPDI for uploading.

I am able to program using the standard Microchip programmer:

pymcuprog erase  -t uart -d avr128da28 -u /dev/ttyUSB2
Connecting to SerialUPDI
Pinging device...
Ping response: 1E970A
Chip/Bulk erase:
- Memory type eeprom is conditionally erased (depending upon EESAVE fuse setting)
- Memory type flash is always erased
- Memory type lockbits is always erased
Erased.
Done.

pymcuprog write  -t uart -d avr128da28 -u /dev/ttyUSB2 -f /tmp/arduino_build_417907/da28_mands_test.ino.hex
Connecting to SerialUPDI
Pinging device...
Ping response: 1E970A
Writing from hex file...
Writing flash...
Done.

And then you get up, make a cup of coffee, and by the time you're done finishing the verification.

This is fixed in master. It was an old version of the included YAML library. And this is written in Python not Ouroboros so they have no prohibition on changes tha aren't backwards compatible.

Any suggestions how to fix this? Arduino claims there's no update available, is there a way to force it to pull the latest code from GitHub?

[SpenceKonde]

You don't want to pull in the code from the github repo, it is completely hosed atm. I am working full time on fixing this please be patient.
