Problem: I want to use my JTAG ICE mkII or AVR Dragon to program an
Xmega device through PDI. The documentation tells me to use the
@emph{XMEGA PDI adapter for JTAGICE mkII} that is supposed to ship
with the kit, yet I don't have it.

@item
Problem: My ATtiny4/5/9/10 reads out fine, but any attempt to program
it (through TPI) fails. Instead, the memory retains the old contents.
Solution: Mind the limited programming supply voltage range of these
devices.
In-circuit programming through TPI is only guaranteed by the datasheet
at Vcc = 5 V.
@item
Problem: My ATxmega@dots{}A1/A2/A3 cannot be programmed through PDI with
my AVR Dragon. Programming through a JTAG ICE mkII works though, as does
programming through JTAG.
Solution: None by this time (2010 Q1).
It is said that the AVR Dragon can only program devices from the A4
Xmega sub-family.
