The SDK currently does not support OTA. You can refer to the following solution:
On Linux, write the upgrade file to the MMC card, set an upgrade flag, and reboot the device.
U-Boot will check for the presence of the flag and perform the upgrade if it's found (refer to the commands below

ext4load  mmc 0:2 0x1000000 /sysimage-sdcard.img.gz  && gzwrite mmc 0 0x${fileaddr} 0x${filesize}

).
After the upgrade is completed, clear the upgrade flag.

On Linux, fw_printenv and fw_setenv can be used to read and write U-Boot environment variables.
