How to switch emmc boot0 / boot1 in andoridN

[zhuchaozhu]

I have currently booted from emmc boot0, but I can't dynamically switch from emmc boot1 on the next boot.

I want to dynamically switch emmc boot0 or boot1 to start, but the trouble I am having now is that I can't switch emmc boot1 such as echo 1 > ../bootcomfig, and there is no mmc command in the system. My kernel version is 4.9, AndroidN imx6qp platform.

Looking forward to your reply，thank you。

Hello,

Have you tried to change the mmc boot during u-boot?

You can do it with the below command 

setenv fastboot_dev mmc1

Hope this can help you.

Best Regards,

Diego
