I'm now not sure about anything in this bug report...: 172K hdk2svr-2.00.hex 156K hdk2svr-2.01beta.hex
Checked second unit and everything went smooth.
Went back to the first and took the risk of running:
# dfu-programmer atxmega256a3bu erase --force --suppress-bootloader-mem
Amd then I was able to flash it successfully :-)
It looks it's random. It can work or fail with exact firmware file version. And it works(or fails) consistently across boot(of HMD). Not sure if it would mean that my HDK2 has broken RAM or something It's not firmware version/build dependent.

IIRC this is from the "suppress bootloader mem" flag, you're intentionally not clearing some flash.

But I always used the same command(copied it over), and after some HMD reboots it failed and sometimes not (I was worried 1st time I saw it and was scared to not reboot[to not brick permamently], so tried flashing different firmwares. After reboot every of this firmwares flashed cleanly.
The problem is that it's not reproducible.
yeah, unfortunately I don't have time to dig into it. If you want to, you're welcome to, and if you find a bug + fix it, I'll merge a fix, I just can't look into it myself.
(Long ago, I did consider combining the firmware hex with the bootloader hex for flashing...)
I didn't exptected that you would work on harmless bug(it's fortunately not bricking HMD,but it looked scary at 1st) for long ago abandoned hardware. I simply wondrif my HDK2 unit is broken or if it's general problem with this HDKs(or firmware). If it's general problem(not my unit), then maybe it should be left as 'open' (if it's not fixed)
