whoops. Linux newbie fail  

seems that i've renamed the bitstream file to bitstreams instead to copy it into a bitstreams folder.

I think this is a mistake or something is missing in your readme:

Copy the bitstreams to      /opt/bin/bitstreams

you have to create the bitstreams folder first an then there is a / after bitstreams missing, i think.

EDIT: OMG! It works! Thank you so much! In the next few days, I try to add some information for ztex boards for your readme.
