[En-Nut-Discussion] MMnet01 .conf problem ... I guess

I know this is an old post, but my problem is still there.
As Harald correctly points out below, it is when the size gets larger than
64kB I run into trouble. Avrdude detects a mismatch when verifying the
downloaded code.
Can anybody please suggest a robust combination of an Avrdude version (or
any other programming SW) and some programming hardware (I have used usbasp,
JTAGice clone and the AVRISP (parallelport and a single 74hc244). Allthough
JTAGICE verifies the downloaded code, I still seem to experience the same

This is so annoying, as I really want to experiment with the Nut/OS.
