[U-Boot-Users] How do I boot VxWorks (6.3) image with u-boot 1.1.3 :: mkimage entry point and address ?

[Chaffin, Michael]

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
	## Start Addr      = 0x00200000
	=>
	=>
	=>
	=>
	=> bootm 0x00200000
	## Booting image at 00200000 ...
	   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?
