I developed a board / app. for a client using '64A3 and MKII ISP unit. I got it to work without using a pullup on PDI's reset.I built the 1st brd. and it worked, then got damaged( xmega toasted ). He wanted 2 boards ttl. and the 2nd board uses a '128A3 as a replacement, Digikey's out of stock on '64A3. NOW I can't access either one !!

1) With no p.up, the ISP'orange led blinks ( didn't do that before ).

2) with a p.up of 1K, or 4.7K or 10K, the led's steady green, but I can't even read signature ( voltage is read correctly ). Studio's error msg. says check I/F connects.

3) Once I did reverse-connect Vcc -- PDI_data and Gnd.--PDI_clk. wires to the ISP, BUT I still got the #1 behavior before I did this. My ISP unit, made in 2009, still works on tinys and megas. Additional tools are 1) and 2) from my sig and 3.4 V system.

Any ideas ?

1) Studio 4.18 build 716 (SP3)
2) WinAvr 20100110
3) PN, all on Doze XP... For Now
A) Avr Dragon ver. 1
B) Avr MKII ISP, 2009 model
C) MKII JTAGICE ver. 1

Have you tried the MK II on another target board to verify the MK II still works? If not it could be the ribbon connector.

If you are using avr studio make sure that the ISP is set to PDI mode and NOT ISP mode. Make sure you've selected the correct device before attempting to connect. I've had avr studio select the wrong settings on startup for some reason after having 'remembered' my last used settings several times in a row.

Rotating :evil: the xmega :evil: by 90 degrees :evil: has :evil: fixed :evil: it !! I'm just glad that it survived and VERY GLAD I took a hard look at the chip orientation 1 last time before trying to solder magnetic wire to the JTAG I/F ( would have been wrong pins of course ) !!! :? :roll: :roll: :roll:

Sounds familiar. We had some boards come back from the fab house with some chips installed 90 or 180 degreees out of phase. Thought was that some parts might have fell out of the pick and place machine and were put back in the hopper rotated round.

We had one piece that wouldn't "work right" from the board house. As comms didn't work to the setup program on the PC, we looked at the clock speed.

Sure enough, it was way off at the crystal. Examination showed a double-stamp--a different frequency crystal must have fallen into the wrong batch during packaging.
