Hello everybody,
There is no switch in the ISP unit. One has to open the covers and there is a provision on the PCB to solder a two pin jumper (taken out of berg connector). Once the soldering is done, plug in the jumper and power up the unit and after a short while the jumper can be removed. Now the unit ready to program.
Note: the power to the ISP is drawn from the target board and through the ISP programming connector. While the ISP unit is being upgraded, the MISO,MOSI and other pins must not be connected to the target board. Therefore use only power and ground pins of this ISP connector to power up the ISP unit. I do agree that this is a bit of a long procedure, but thats the system is designed.

There is no button in the AVRISP. In the docs somewhere it says to power theAVRISP( the led comes on, cycles colors and settles on green I think). Youshould not connect it to your target as this usually mungs communicationswith the micro's in the ISP. Once the AVRISP is idle(green status led),clock OK to program it.This is a real pain and your lucky. In my experience, a lot of the time, theISP will mung code in it's secondary MCU and become dead. Atmel has anappnote on recovering but I have yet to be successful.This message will happen every time you update studio, a choice I think abig mistake. The funcinality should have been left in AVRStudio and the ISPcode left frozen.Hope this helps.Let us know how you make out.Jim-Original Message-From:

The firmwarecorresponding to this installation of AVR Studio is 2.00. Press OK tolaunch the upgrade program to perform a downgrade, or Cancel withoutdowngrading. NOTE! Correct operation is not guaranteed if a downgradeis not performed."If I press Cancel it seems as though everything works.If I press Ok, AVR Studio launches the Atmel STK500/AVRISP Upgradeprogram but after doing something to the AVRISP so that the LED goes outit then reports that
no programmer could be found, and thus no update isperformed, and then AVR Studio can't detect the AVRISP until I close AVRStudio AND cycle power to the AVRISP.How do I get rid of either the first warning or the error updating sothat I can resolve this?I have looked online at atmel.com and avrfreaks.com, with no luck.___AVR-GCC-list mailing listAVR-GCC-list@nongnu.orghttp://lists.nongnu.org/mailman/listinfo/avr-gcc-list___AVR-chat mailing listAVR-chat@nongnu.orghttp://lists.nongnu.org/mailman/listinfo/avr-chat___AVR-GCC-list mailing
