Hi,
Yes, I’ve seen the example script for boot selection. The problem is I don’t know where to integrate it. The image flashed on emmc has no boot partition which would usually be mounted at /boot and contain boot.scr script. Instead, bootloader, kernel image and other components are placed to separate raw partitions at the beginning of the emmc. Then go rootfs and data ext4 partitions. Here is the layout:
 
flash=mmc,1:loader:idb:0x8000,0x280000:idbloader.img;
flash=mmc,1:env:env:0x3F8000,0x8000;
flash=mmc,1:parm:parm:0x400000,0x0400000:param4sd.txt;
flash=mmc,1:uboot:raw:0x800000,0x0400000:uboot.img;
flash=mmc,1:trust:raw:0xC00000,0x0400000:trust.img;
flash=mmc,1:misc:raw:0x1000000,0x0400000;
flash=mmc,1:resc:raw:0x1400000,0x0C00000:resource.img;
flash=mmc,1:kern:raw:0x2000000,0x2000000:kernel.img;
flash=mmc,1:boot:raw:0x4000000,0x2000000:boot.img;
flash=mmc,1:rootfs:ext4:0x6000000,0x117800000:rootfs.img;
flash=mmc,1:userdata:ext4:0x11D800000,0x0:userdata.img;
 
Best regards,
Mikhail
