There are several limitations in current SerialUPDI/AVRDUDE integration,
listed below.
At the end of each run there are fuse values being presented to the user.
For most of the UPDI-enabled devices these definitions (low fuse, high
fuse, extended fuse) have no meaning whatsoever, as they have been
simply replaced by array of fuses: fuse0..9. Therefore you can simply
ignore this particular line of AVRDUDE output.
Currently available devices support only UPDI NVM programming model 0
and 2, but there is also experimental implementation of model 3 - not
yet tested.
Currently available devices support only UPDI NVM programming model 0, 2
3 and 5, but there is also experimental implementation of model 4 - it
has been tested only on a single device, so issues with other devices are
expected. Full NVM v4 mode support will be provided once the hardware is
widely available.
One of the core AVRDUDE features is verification of the connection by
reading device signature prior to any operation, but this operation
