Hi Freaks,

We use the stk500.exe in a command line script with an AVRISP for production programming. I recently upgraded my version of AVRStudio from v4.08 to v4.11. AVRStudio then prompted me to upgrade the firmware on my AVRISP, which I did. Now I'm finding that the newly upgraded AVRISP won't work with the older version of stk500.exe. I've tried un-installing v4.11 and re-installing v4.08 with the plan of down-grading the AVRISP firmware, but now the application just hangs when I try to access the AVRISP.
Anyone know how to fix this?

Dave

The newer studio uses version 2 protocol. Can you use the new version of STK500.exe (which I presume also uses V2 protocol)? Else you may have to manually downgrade to the older version of the firmware. (stk500.ebn)

Search the forums (here or in the AVR GCC Forum). This has been discussed before.
