VxWorks boot firmware won't boot on rev2 T4240QDS

We are trying to boot VxWorks on the T4240QDS.  Booting the VxWorks kernel direct from u-boot is not supported, so we need to first flash the VxWorks boot on the board, boot from it, then use it to download and boot the VxWorks kernel.

 

Using u-boot in bank 0, we've been able to download and flash the VxWorks boot into bank 4, but after we change the switch setting to boot from bank 4, it fails to boot (nothing comes out on serial).

The VxWorks boot is for Rev.1 and we have Rev.2.  Is there some change in Rev.2 that could be causing it to fail? Perhaps a change in DIMMs?

 

Thanks!

Serge
