Thanks. :-)
That avrdude.conf.in file seems to work!

...but only after adding the definition for the jtag3updi progammer from 
the original avrdude.conf.in:

-----
programmer
 id    = "jtag3updi";
 desc  = "Atmel AVR JTAGICE3 in UPDI mode";
 type  = "jtagice3_updi";
 connection_type = usb;
 usbpid = 0x2110, 0x2140;
;

$ ~/project/.../avrdudue/installation/bin/avrdude -p t1604 -c jtag3updi -P 
usb -t

I still get that "avrdude: bad response to read memory command: 0xa0" tho'. 
Do you know what that means?



It seems to be able to read the flash, the fuses, prodsig and other regions 
too, which inspires some more confidence:

What's the main difference between the repos / reason for the fork? Which 
one is the official version?



Thanks so much for your help!

I really appreciate it. I'll try to program some parts now and see if I run 
into any more problems.


Should I file a bug / send a patch for this?




Best wishes,
@ndy
