also vxworks bootloader can not run u-boot elf.why this happens?

Plain and simple: the VxWorks bootloader does not support the elf file format. How to get a standalone application running with the VxWorks bootloader is a question for a VxWorks mailing-list.

FWIW: Usually (can probably be configured otherwise), the VxWorks boot loader is able to load ELF objects all the same, but obviously this is not sufficient for what the OP wants to do: the hello world example expects to be run under U-Boot, and the uboot ELF binary expects to start out of some (flash) ROM. Convincing both u-boot or hello world to behave otherwise requires considerable in-depth knowledge.

You're definitely right about the mailing list, though :-)
