Hi Diwakar,

Hi Diwakar,

some image is save on ospi flash, some image is in emmc.

This is the boot flow as below.

tiboot3.bin and u-boot-spl.bin is save on ospi flash.

the other image is save on emmc.

1. i want to update tiboot3.bin and u-boot-spl.bin when on  u-boot command mode. but i cannot access spi flash on  u-boot command mode. 

you can see my last show picture. if i input 'sf probe', it fail.

How to solve this issues?

2. i want to move u-boot.img from emmc to ospi flash. it is mean that u-boot.img is save on ospi flash.

Is the u-boot.img only burn to this address 0x280000? can i burn to any other address?

Hi xie jc

Why you want to keep some images to ospi and some to emmc , our default sdk doesnt support this mix and match any specific requirement

for this ?
