Re: [avr-gcc-list] uisp and new STK500 firmware?

Actually, I'm all the way at 1.41 now (oops). I was running 1.40 for
awhile (programming a 4433 none-the-less, which won't reenter
programming mode and has other buglets - kind of infuriating :)). The
whole reason I upgraded is to try popping in the Mega 163 I had lying
around. It didn't seem to actually hold anything in its flashrom (eeprom
was ok). Swapped out the power supply, confirmed it was getting +12V,
etc. I decided to try AVR Studio just for the sake of trying, which, of
course, wanted me to move to 1.41 (recently had to rebuild windowsland,
so I fetched the latest version of AVR Studio without looking). I
blindly did, determined that my Mega 163 was a very sad Mega 163, booted
back into Linux, and uisp was now also sad. Great :)

Looking over the little online information I can gleam from 1.41, its
supposed to allow the STK500 to support the STK502 for the Mega 169.
While the STK502 looks kinda cool (LCD anyone?), it did seem to change
the protocol :).
