[En-Nut-Discussion] STK500 not working

[Harald Kipp]

Dan,

the STK500 has a complete different hardware and unfortunately
our little adapter is not supported by Atmel. So Atmel's
software won't work on our adapter.

The good news is, that the source code of the adapter's firmware
is provided
http://www.ethernut.de/en/isp/index.html
including an Ethernut application, which re-programs the adapter.

I assume, that this part of sisp.S

         ;
         ; Software version major
_gp81:
         cpi     r_parm, 0x81
         brne    _gp82
         ldi     r_data, 1
         ret

         ;
         ; Software version minor
_gp82:
         cpi     r_parm, 0x82
         brne    _gp83
         ldi     r_data, 14
         ret

needs to be changed.

Anyway, AVRStudio 4.09 works fine with SISP 1.1.1. You can
simply ignore the update message.
