Hi,
the linux32-trick is neat...but it seems a little more to be done
here.
I straced the whole thing:

Same happens, if I feed the whole glory of necessary commandline
switches and the hex-file into this little beast.
"No such file or directory."
Unfortunately I have no clue, what is missing here...
(and it is definetly no script, which #!<something> couldn't
be found.
Why does the task of flashing firmware walk hand in hand with mental illness so
near at the abyss of bricked hardware that often ?
Why can't it that easy as scripting plain TeX?
;)
