I'm a lazy "dog". A lot of board diagnostic, HW identification mechanism and manufacture utility are already there along with the VxWorks bootrom. I don't want to spend time in porting them. To turn on the Linux on the board through your U-Boot has, in deed, given me a lot more convenience in supporting other 3rd part software packages than VxWorks.

Thanks for you and the other developers to provide so great a tool. It is worth of a lot lot money.

Best Regards,
Tony

Why are you making all this so complicated?  What  do  you  need  the
VxWorks  Bootrom  for?  Just  install U-Boot in flash, and let U-Boot
boot either Linux or VxWorks.
