SDcard boot SDK 1.8 LS1021a

Hello all,

 

I am having quite a bit of trouble building a uboot, kernel, and rootfs in Yocto (SDK 1.8) and then deploying it onto an SD card and booting it on the LS1021atwr board X2.

 

I've tried deploying just uboot to the sd card by writing it directly to the card using a dd command:

dd if=u-boot.bin of=/dev/sdb bs=1024 seek=8

 

I built uboot by changing it's config to sdcard: UBOOT_CONFIG ??= "sdcard"   and then forcing a rebuild.

But for some reason I can't get just my uboot to boot. I've tried a ton of different switch settings and still can't seem to figure it out.

 

 

Could someone please detail the steps necessary to deploy a built system(uboot, kernel, and rootfs) to an SD card and boot it on the LS1021atwr?
