I am running on kernel 4.19.46 Ubuntu distro. 

I have a LS1021a - twr eva board and it's booted from SD card but in the future will be an external eMMC. I am thinking to have two copies of image in the system if one is broken the u-boot or bootloader can detect next time upon boot and it will switch to the working version automatically. Any one knows how to achieve this purpose?
