I wrote the tool because I found that there is no good software even
in the proprietary software world.

There is a severe bug in DfuSe tool on Windows which stops Gnuk
development (or any "real" development).  When the file to be loaded
includes a page filled by 0xff, DfuSe tool on Windows fails to update
flash ROM on target board.  Because of this bug, you could write Gnuk
to your target board only once.  Now, with the tool in Gnuk, you can
update the flash ROM again.

Please visit at http://www.fsij.org/gnuk/ for Gnuk news.  Now, it
has index to access all entries.

P.S. I will talk about Gnuk at FOSS Asia: http://fossasia.org/
