[U-Boot] bootvx on MPC8572

[Robert Rzepiela]

Hello

I am running u-boot.2009.01 on DS-8572 (whitefin). I use tftpboot to 
download
an elf image (from vxWorks release for the eval) and try to run it with 
"bootx".
After messages about loading text etc etc. the board hangs right after 
printing
"Starting vxWorks at ...". I am using default bootline .

Is there something obvious I am missing here or I need to get ready for 
JTAG ?

thanks
