I bought a new STK500 starter kit and the "Embedded C Programming and the
Atmel AVR" book last week. I have the attached the STK500 and it downloaded
the firmware update with no problems so I know the connection works. I'm
working through Appendix B "Getting Started with CodeVisionAVR and the
STK500" in the book but when using the CodeVisionAVR IDE to program the
90s8515 controller I get the "STK500/AVRISP communication error" message.

I've checked the possible problems as described in the error message:
  - The STK500 power supply is turned on, the 3 led's light up.
  - The programmer type in Settings->Programmer is set to Atmel
STK500/AVRISP
  - The COM Port is set in Settings->Programmer, I have both COM 1 and COM 2
available on one computer and COM 4 available on another. I'm getting the
same error on both machines.

I'm sure I'm probably overlooking something simple but haven't found the
problem yet. Any suggestions?

The latest firmware update (Astudio 4.11) might be incompatible with CV.
Atmel changed a bunch of stuff and broke the various download tools that
come with the GCC tool chain.  The interim solution is to get a previous
version of studio (3.56, for example) and go into the stk500 directory and
figure out how to download that firmware. It isn't hard, but it has been a
while since I did it so I can't give you specific instructions.  You use
"avrprog" and the bin file in the directory.

Cheers!
