I have tried reading and writing all the Xmega memory sections listed in part
command and also in the manual. Four of them returns not supported error:
lock, prodsig, apptable, application. The rest works fine. I've found one
other report of this problem in mailing list in February, without reply.
If I get it right the application + apptable section are same as whole flash
section, so there is workaround possible. But no access to prodsig
(calibration and factory data) and lock is more problematic.
I used avrdude 5.10 with Dean Camera's AVRISP-MKII clone programmer firmware
(-c avrisp2). I verified with the programmer author that those sections are
accessible from AVR Studio.
