Online Update Method

Copy the prepared swu update package file to the SD card (the SD card file system format must be FAT32), and insert the SD card into the card slot.

Restart the system or power it off and then back on. Press Enter to remain at the U-Boot command line. The new version has removed the boot countdown; it has been changed so that the U-Boot command line is entered only after pressing the letters "db".

Update method for GW101-D512E4 configuration

setenv mmcpart 2
run bootcmd

At this point, the system will enter the recovery system, automatically detect the swu file on the SD card, and then automatically update the system.
