(...) ReHi Jürgen, yes this is a trivial job, but what should I learn from this packets ? fwflash returns no error back to commandline ... Does this mean fwflash works blindly and returns no protocol or packet errors ? Why is the result "success" (...) (19 years ago, 26-Jul-07, to lugnet.robotics.nxt.nxthacking)

Hi Christian, (...) you could add some code in lowlevel.c to dump the USB packets, and then look if you see anything wrong. Jürgen (19 years ago, 26-Jul-07, to lugnet.robotics.nxt.nxthacking)

(...) Hi Jürgen, very good idea. Please give me some hints where to start. I haven't found any --verbose command line parameters, yet :D OK, I'm trying to read the source again, expecting ENDIAN problems like every time using PPC and SPARC :-D Bye (...)

(...) It hasn't, Elizabeth - I'm not upset at John, and he knows *far* more about programming than I do.

(...) It is not a rather awkward option, imho. That's like saying breaking out of an infinite loop using a flag is awkward and that it would be better to have some form of stop loop keyword that you could use from outside the loop instead.
