Failed to initialize SPI flash at 0

Hi,

I am using DM8148 EVM. I am able to boot from MMC/SD successfully.

But here I want to boot from SPI flash.

So from u-boot prompt of sd boot I have fired bellow command,

sf probe 0:0

But this gives me error "Failed to initialize SPI flash at 0:0"

I have turned SPI switch on in SW2(NAND/SPI boot).

Is there something that i am missing ?

Thanks in advance,

Hi Renjith,

Yes I have build first stage u-boot for SPI flash. But Its a second thing.

The issue is, I am not able to initialize flash at 0:0.

I can't read from or write to flash untill i fire sf probe 0:0 command successfully.

Shabbir,

Can you share the complete logs of the steps that you are following?

It should be resolved by change the SW2 to 01[NAND/SPI] of DM8148 EVM
