See audit trail of that patch.

Current SVN works for me on that board.

OK. given the audit trail of patch #9757, in particular r1436 breaking this again, I just ordered an ATtiny817 devkit.

This is still an issue on revision 1476. See also https://savannah.nongnu.org/patch/?9757

Don't have an ATtiny817 board to test with.

A number of things have been changed recently, can you verify the problem still exists?

I forgot to specify that it's the ATtiny817 Xplained mini board (from Atmel by markings) that has the issue.

I built the latest version with this summary:

```

When I issue `./avrdude -p t817 -c xplainedmini_updi -C /etc/avrdude.conf` then it errors out with:

```
avrdude: jtag3_edbg_recv(): Inconsistent fragment number; expect 1, got 0

avrdude done.  Thank you.
```
