Hi Marc

Thanks for the reply.

I tried reflashing (4 or 5 times).  I have also made clean and 
re-compiled buildroot to give me a clean filesystem and Kernel and then 
re-flashed but still get the same error.  I thought it must be my boot 
args but these all seem to be correct when compared against the Wiki.

I'll let you and the list know how I get on.  I have a second Connex 
board that needs to be done (upgraded / reflashed) but don't want to 
start that one until I get to the root of the problem with this.

Thanks

Gareth
