VxWorks 7 rebooting with UEFI payload

[Moorthi M.s]

Hi,

I am developing coreboot along with UEFI payload for a custom board derived
from CFL H RVP11 CRB.

Modifications are done as per the custom board and board was booted to
CentOS and Windows.

When we try to boot VxWorks 7 with native UEFI loader, the board was
rebooting.

But the same UEFI loader and VxWorks image is booting with BIOS version of
the same custom board.

Is there any modification need to be done to boot VxWorks 7?

Thanks & best regards,
Moorthi S
