using SPI in the EVM

hi,

i have the EVM with the touch screen.

i'm using SDK 05.05.00.00.

when i'm starting u-boot i want to use the comand to connect SPI to the NOR flash.

this is the line i want to run: sf probe 0x0

and this is what i get:

 SF: Unsupported manufacturer ff

 Failed to initialize SPI flash at 0:0

can someone help me with this?

my plan is to burn the NOR flash with u-boot. but currently i can not even access the SPI...

thanks in advance :-)
