Hi guys:

I have a JTAGICE MKII unit that works very well, but now, I need to debug using PDI interface (on a Xmega128A1 chip)

My question is (since I havn't the chip in my hands now) if I can debug using PDI interface.

I read the Avrstudio manual and it says that there are two conditions to be able to debug in PDI mode, one, the serial number of the MKII must begin different than A0.... (which is not my case, the serial # in my MKII begins with A00) and the second, an internal green led must lit when the MKII is connected on USB (which is mmy case, it lits)

Now, I havn`t any device to test for PDI capabilities, and the Astudio manual isn't clear (or it's not clear to me) if ANY or BOTH conditions are needed to debug in PDI mode.

Any help will be welcomed!
Thank you

Nachus

I have used PDI with the JTAGICE MKII and the Xmega128A1 chip.

However the JTAG must be one of the newer types with B0xxx serial number. But just to make things complicated it seems that "newer" newer types are starting with A0xxx again. So if you bought the JTAG recently it may be OK.

Hi John:

Yes, I bought it recently (some six or more months ago)
It seems that there's no way but to try a debug session...

Thank you

The later versions have an LED completely inside the plastic case next to the USB connector in back. I'm not sure what it lights up for, but it does light up when I use it (I use the USB with an external power supply). If you have this LED you should have PDI.

Please refer the "AVR Studio Help-->AVR Tools User Guide-->JTAGICE mkII User Guide-->Introduction-->Hardware Revision" where describes the tools that can work and not.
