Thanks a lot for this nice contribution!

I replaced all the ATxmega* definitions in avrdude.conf.in
by your configuration snippet (SVN r1222).

I attach a file with the right settings for all XMEGA MCUs. This file is automatically converted by a Python script from this table:


(file #25825)

Sure, I'll check all XMEGA datasheets and will post a patch with the correct values. Please disregard the avrdude.conf patch I posted just a few minutes ago. Although my main interest is in the ATxmega32A4, for the benefit of the community I will check all XMEGA's.

Seems you are right. Well, fixing just one Xmega device
doesn't make much sense, would you be willing to browse
all the datasheets, and make a suggestion for an updated

The previous version (all page sizes set to 0x100) was just
wrong, too, and it fell onto my feet when implementing
page erase.

The datasheet of the XMEGA A4 devices mentions that the "User Signature Row" is one flash page in size. In the trunk's version of avrdude.conf.in all XMEGA devices share the same usersig configuration, yet they are not the same:

Page Sizes (words):
ATxmega16A4: 128
ATxmega32A4: 128
ATxmega64A4: 128
ATxmega128A4: 256
