I am thinking of migrating up from mega series to xmega.  It's not clear to
me, however, if you can still program them in the "traditional" ISP way.
There seems to be something called "PDI" now, but still using a 6-pin
connection.  It's pretty clear you can still do it through JTAG, so that's
not an issue.  I'd appreciate it if someone could explain in a nutshell PDI
vs old ISP.  Thanks, Steve.

PDI uses 1 dedicated pin + reset so there is no "wasted" pins,
ISP uses 3 SPI pins + reset.

PDI can also do debugging if you have the right tool
like a JTAG Mk2 of later types.

Remember the Xmegas do not run at 5V.

Thanks, John.  I have both an Atmel STK500 and JTAG Mk2, and both have 2x3
and 2x5 headers on them for programming.    I presume the 2 PDI pins should
map to 2 pins on each of these headers, but the manuals for both of these
don't mention PDI at all.   How does one connect it up?   Is there any way
to use the old ISP with xmega's?   Steve

The Tool section of the AVRStudio Help section shows the PDI to SPI mapping.
Alas can't run AVRStudio on this Linux box or I'd copy and past that
section.

There is no way to use the old ISP with an XMega.  No way to use the STK500
that I know of, must use the STK600, JTAG MK-II or the AVRISP pod, which
will do PDI if it is not to old.

The AVRISP Mk2 will do PDI programming for Xmegas.
See AVRISP mkII User Guide in the Tools help of Studio
under 1.5 Supported Devices. Also 2.5.2 PDI Interface
show the wiring for PDI. Please note that PDI seems
to be using 0.050" pitch connector and you can buy an
adaptor for it. Mine came with the JTAG Mk2.

The info for the JTAG Mk2 can also be found in the help
files under "Connecting to a PDI target " and
Figure 4.4. PDI header pinout.

Don't use the STK500 to programme it, even if it could. As I recall, the
STK500 is 5V operation only and will likely damage the XMEGA running on the
lower voltages.

The STK500 has voltage translators and handles low voltage just fine. But it
does not do PDI (AFAIK).

 Yet another PDI option is Dean Camera's open source AVRISP clone.

You need the current JTAG Mk2. The original one doesn't support it.

That number sounds like an ATAVRISP2 number.  My ATAVRISPISP2 has the number 20071005 and it can do PDI programming (after a firmware update, of course).

My JTAGICE MkII has a serial number beginning with A09.  It, too, can do PDI programming after updating its firmware.

If you have a new enough hardware version, yes.  On the Help menu in AVR Studio, select "AVR Tools User Guide".  Then select JTAGICE MkII and a help text viewer will appear.  Search for PDI and then select one of the "Hardware Revisions" entries that is found.  There, you'll find an explanation of which hardware revisions will and won't support PDI programming and how to determine which you have.

Leon, do you know just how current current needs to be?  My JTAG Mk2 has
"20071109" on its sticker, presumably that means Nov 2007.   Steve

Well, it's definitely on a JTAGICE MkII.   It sounds though that I don't
have to be concerned about having the correct version on the JTAGICE MkII to
do PDI, because I can just upgrade the firmware with AVR Studio.  Is that
correct?   Steve.

I'm not sure, I've got one of the old ones. You can tell from the LEDs 
that come on when it is connected, but I can't remember the details. 
It's been discussed on the AVR Freaks forum a couple of times.

No, you need the current model.

My AVRISP mk2 says 20080801 and programs xmega chips just fine.

From the command line you must have the -md option specified for PDI programming.

What about the Dragon?

Can it program the XMegas, either JTAG or some other mode?

It depends on the version of Studio used. But all the info is at
your fingertips in Studio's help files under supported devices.
