I have a problem with upgrading Studio 4 & AVRISP. I had a working configuration on Windows 95 (Studio 4 v. 4.06 b 223). I installed Windows XP on another machine and downloaded Studio 4 v. 4.17 b 666; it installed o.k. as far as I can tell. Upon connecting to the AVRISP programmer it prompted me to upgrade the firmware to a current version and I did so. As others in the forum have noted, AVRISP communication was then lost.
I followed the DN_010.PDF directions to manually reprogram the AVRISP device with the stk500.ebm file. That process (after some trial and error) completed and indicated that verification was successful. Nevertheless, AVRISP communication still fails. I also ran the upgrade.exe file, which went through all the erase, program, verify, steps but did not give a usable AVRISP link.
Here are the relevant versions:
AVRISP (Mk I) a genuine Atmel product purchased many years ago; NOT a 3rd party board or a clone. In the "Advanced" tab of "Tools -> AVR Prog" it reports "AVR ISP", Target SW rev. 3.1, Device signature 00 01 02.
On-board chips are: 90S1200 and 90LS8535.
Studio 4, version 4.17, build 666.
The connect dialog box (AVRISP, COM1) fails with an error message "connect failed." At one point, among many trials, a connect attempt gave an error message "Please finish upgrading before reconnect." I have not been able to reproduce that condition after running upgrade.exe.
A target board is patched to supply only 3.3 Vcc and Gnd and SCK. Without the SCK there is "no supported board found." With SCK there is "connect failed." (Without SCK the manual program mode fails.)
I am not intending to do anything fancy with ISP, just flash and EEPROM programming from .hex files from the Atmel assembler, so maybe an earlier version of the AVRISP firmware is the best choice. I see references to V2 of the communication protocol required for the current version of Studio 4 so maybe I would have to "downgrade" Studio 4 to an earlier version if the AVRISP (Mk I) hardware cannot support that protocol.
Hoping that somebody has ideas to try or, better yet, a clear solution.
