Orange Pi Zero Plus 2 (H3) boot device

Recommended Posts

Hello to everyone!

 

I am trying to configure dual boot using u-boot. But I've got some misunderstandings, maybe someone will help me with that problem.

 

When I'm booting from SD card everything works fine:  rootdev=/dev/mmcblk0p1 (armbianEnv.txt) or rootdev=UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX in both cases.

 

When I'm booting form eMMC something goes wrong: I can not set rootdev=/dev/mmcblk1p1 cause in this case I've only error message:

But if I'm setting as rootdev=UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX everything works fine. 

 

Maybe it is bad way to use /dev/..., but I need it. 

 

So, I tried a lot of ways to fix that and found that, such situation only with legacy kernel, mainline works without any issues.

 

Where I'm doing wrong?
