vxworks through spi

hello,

i managed to start the EVM with u-boot through spi and the NOR flash. with the help of this (http://e2e.ti.com/support/arm/sitara_arm/f/791/t/246353.aspx)

now i want to do it with vxworks boot.

in the Windriver help they explain what to do to make the vxworks be on the NAND and it is working for me. (starting with u-boot, transfering the boot file with tftp, writing it ro the NAND, change the swittches to boot from NAND and walla).

what do i need to do to make vxworks start from NOR (SPI)?

thanks in advance,
