I have a working system, PowerPC embedded in Xilinx Virtex II Pro, that does boot into Linux using u-boot 1.1.3; but I need to load a VxWorks (6.3) image and boot from that. I have read the documentation, but I don't know what my entry point for mkimage to use, sysInit( )? What should my load address be?

To date I have used the following command

mkimage -O VxWorks -A ppc -C none -a 0x00 -e 0x00 \
  -n vxWorks1a.msc -d ./vxWorks ./vxworks1a

I load the resulting file (vxworks1a) to the device, and attempt to run the it

=> loadb 0x00200000
## Ready for binary (kermit) download to 0x00200000 at 115200 bps...
## Total Size      = 0x000e09b6 = 919990 Bytes

   Image Name:   vxWorks3.msc
   Image Type:   PowerPC VxWorks Kernel Image (uncompressed)
   Data Size:    919926 Bytes = 898.4 kB
   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK
OK

The system never returns from 'OK'. What am I doing wrong?
