SPL: failed to boot from all boot devices

[navinagaraj]

Hi I tried to boot the wandboard-solo, I followed the steps " https://github.com/TechNexion/u-boot-tn-imx/blob/tn-imx_v2021.04_5.10.72_2.2.0-stable/board/wandboard/README " to bring the u-boot on SD card. But facing some issues on it.
can anyone help me to boot wandboard for SD card ?

Error Log:

U-boot Files created after build:

Did you find a way to make it boot?

@SnappierSoap318 @navinagaraj :

The error message is that the u-boot file of the FAT partition cannot be read. I checked the documentation steps you referenced. It should be a description of the mainline source code.

• Flash the u-boot.img image into the SD card:

sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync

The u-boot file is loaded by the SPL from the boot partition, which is a FAT filesystem in the first partition.
You can refer to the following web link:

@ray-chang Using an old version of the source ( 2017.11), I was able to compile and flash it without any issues.

The difference between u-boot 2017.11 and 2021.04 is that u-boot.img is placed in 1st FAT partition instead of RAW in u-boot 2021.04.

So it would require to put u-boot-dtb.img in 1st FAT partition.

it Worked!

what i did was copy the u-boot-dtb.img file to the first FAT partition using
sudo cp u-boot-dtb.img <partition>
and it worked
