IMX8M Nano dual u-boot support

[mabar70]

Greetings!

I am investigating the way forward to use dual boot loaders (u-boot) for the IMX8M Nano platform on eMMC.

I found this document and table 28.
https://www.nxp.com/docs/en/user-guide/IMX_LINUX_USERS_GUIDE.pdf

The lack of a dual boot table there for the platform made me hesistant.

Does the IMX8M Nano even support dual bootloader configuration?

And if so, how to set it up? Are there some indications to follow?

Thanks a lot for any help!

Hello,

There is no documentation about the dual boot of i.MX8x, but you can use a hypervisor and have a dual boot or dual OS.

Hi, @Bio_TICFSL . thanks for your reply.

Not sure I understand hypervisor in this context, though. 

Can you give a bit more information or examples?

It seems that Android is doing dual boot looking at:
imx8mn_evk_android_dual_defconfig

It has the 
CONFIG_DUAL_BOOTLOADER=y

Thanks!

Hello,

Yes, that works with hypervisor, here you can find the jailhouse page:
