Enabling SPI Mikrobus Flash from u-boot on imx7 SABRE board

Question asked by Sonu Abraham on Oct 30, 2018

Hi,

 

I am trying to access SPI flash connected to microBus on the imx7 SABRE board.

 

I am getting the following error when trying to probe flash device from u-boot

=> sf probe
SF: unrecognized JEDEC id bytes: 00, 00, 00
Failed to initialize SPI flash at 0:0

 

I am using u-boot ver U-Boot 2018.07+fslc+g1e13b91

 

I would like to know what are the changes required in u-boot to detect the SPI flash ..

 

Thanks in advance,

Sonu Abraham
