Didn't I told you to try the tree I on http://gitbits.246tnt.com ?

I don't know the tree you're using but it doesn't seem to be mine ...
(nor any of the previous version i published).

I you want to have the most "complete" stuff i publish, clone the
mainstream, pull from my ide branch and then pull from the bestcomm branch.

There is also the denx tree but I don't know it's status.

 You would see nothing with the tree of gitbits.246tNt.com with that
command line. You need ttyPSC0 ...
