Dragon and Xmega32E5 Difficulties:
First, thank you to Jim (East Coast Jim) for the Dragon!
Running Studio 6.2xxx, and the Dragon works great programming an Arduino Nano board's M328P using ISP.
Switched to a board with an Xmega32E5, PDI Programming, and nothing but difficulties.
My AVR ISP mkII programs the Xmega fine, so I know the board isn't an issue.
The Dragon will read the PCB's voltage, and will read the Signature, but then I get a "Can't enter programming mode" error, or it might appear to program the chip, but then it fails to verify the chip, (and the program isn't running, so I don't think it was really programmed).
I used several short cables, which all work with the Mega, but none of which worked with the Xmega.
I know the current Dragon manual says:
PDI does not work for Xmega A3/D3- Rev B,C, & E, or A1 up to Rev. K.
As the XmegaE5 is the newest Xmega of the lineup, one would expect the hardware PDI interface module on the chip to have the bugs worked out of it.
Studio didn't ask me to upgrade the Dragon's firmware, (I think Jim nicely already did this before sending me the Dragon).
So, anyone else using the Dragon in PDI mode with the Xmega E5 series successfully?
Thanks,
JC
