Hello,
in U-Boot after following modification (to boot from eMMC)
-----
mmc dev 0
setenv bootargs console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000 vm.overcommit_ratio=5 vm.overcommit_memory=2 root=/dev/mmcblk0p1 ip=dhcp
setenv bootcmd "setenv autoload no;ext4load mmc 0:1 0x82000000 /boot/Image;ext4load mmc 0:1 0x81200000/boot/k3-j721e-common-proc-board.dtb; booti 0x82000000 - 0x81200000"
saveenv

I'm no longer able to boot from micro-SD.
Would you please provide me a procedure to store the right values to boot again from micro-SD.
How to switch back
