[avrdude-dev] programming XMega D3 boot section

[Ralf Glaser, track IT]

Hi @all,

i'm trying to program the boot section of an ATXMega128D3 and it doesn't 
seem to work.

Im using a JTAGICEMK2 in PDI mode with avrdude 5.10.

I can read/write/verify the application section.
I can read the boot section (programmed with AVRStudo 5.1 before) with:
avrdude -px128d3 -cjtag2pdi -Pusb -D -Uboot:r:boot.bin:r

I try to re-program the boot section (after a chip erase) with:
avrdude -px128d3 -cjtag2pdi -Pusb -Uboot:w:boot.bin:r
but the section is still erased even though avrdude pretends to have 
programmed it (avrdude output at end of mail).

I've also tried and failed with the following commands:
avrdude -px128d3 -cjtag2pdi -Pusb -Uboot:w:boot.hex:a
avrdude -px128d3 -cjtag2pdi -Pusb -Uflash:w:boot.hex:a
as well as using a concatenated bootloader+application file (intel hex 
format concatenated with srec_cat).

My question now is: Is this a problem of me using my ATXMega-D 
definitions or is this function not available with my version of 
avrdude/ avrdude in general/ the JTAGICEMK2 / on D devices or am i just 
missing something?

Any feedback from somebody who is using avrdude to program the boot 
section on any XMega device would be welcome to narrow down this problem.

Best reagrds,
Ralf
