PROCESSOR-SDK-AM335X: cannot detect NAND for am335x-evm

Part Number: PROCESSOR-SDK-AM335X

Hi,

I want to boot from NAND. 

I first booted from SD card.

But neither SDK 05.03.00.07 nor 06.03.00.106 cannot detect NAND

I tried to use “nand bad” to check nand, but all display “no devices available”.

How to do for deticting nand??

I use AM335x-EVM GP.

Thanks you.
