Mind the:

»... with buffersize=128 bytes.«

message.

This is supposed to be fixed by the following revision of butterfly.c:

---

revision 1.12
date: 2005/10/20 11:36:19;  author: joerg_wunsch;  state: Exp;  lines: +3 -3
Fix yet another sign extension bug introduced by renaming "unsigned char"
to "char".

Do you have a chance to test a version from CVS to see if this also
fixes your problem?

Hi I've tested the changes but I have a slightly different problem. I'm running OsX Tiger 10.4.3 and avrdude5.0-beta works with the butterfly. Version 5.0 segfaults when it attempts to write to the butterfly. Below is the output and the crash report. This was using a fink install (package info from http://screwdecaf.cx/tools.html). I've tried recompiling from the latest CVS source but I get the same problem.

There are 31 Differences between the 2 versions of butterfly.c any idea where to start looking? Most of the changes appear to be castings. If I use the new butterfly.c with the Beta version it seems to work fine so the problem might be due to changes elsewhere in the program.

Any ideas? Can anyone replicate this problem?

I have just tested the latest CVS  version (as of 24 Jan 06) and it is working great now.... Cheers.

Nick.
