Automatic Detection of USB Drive Upgrade Packages

This manual describes how to upgrade update via USB disk.

First, prepare a USB drive containing the upgrade package update.img to be flashed. Confirm the USB drive’s auto-mount path. Insert the USB drive.

Take my development board as an example, the default mount path of the USB disk is/run/media/sda1

[root@ok3568:/]$ ls /run/media/sda1
System Volume Information  update.img			//U disk is automatically mounted, and update. img is available in the disk.

Now write the boot script in the/etc/init. d path.

[root@ok3568:/]$ vi etc/init.d/S99update.sh

The script reads as follows:

#!//bin/sh
        FILE=/run/media/sda1/update.img				//The path is the default mounting path of the USB flash disk.

        if test -f "$FILE";then			//Judge whether there is update. img in the USB flash disk.
                echo"----------------FILE exist----------------"
                cp /run/media/sda1/update.img  /userdata/update.img		
                rm /run/media/sda1/update.img
                update ota /userdata/update.img
        fi

The format is as follows:

Give permission to self-start script execution:

[root@ok3568:/]# chmod +x /etc/init.d/S99update.sh

Test:

[  128.540609] FAT-fs (sda1): utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!
//The development board can identify the USB flash disk normally.
[root@ok3568:/]# reboot		//Restart the development board
[root@ok3568:/]# ----------------FILE exist----------------		//Successfully entered the automatic upgrade script

find /userdata/update.img
command: --update_package=/userdata/update.img
update: write command to command file: done
update: write command to misc file: done
update: reboot!

Note: After the upgrade is completed, the system will automatically restart twice. The first restart updates some information. The operating user is [root @ buildroot]. You need to wait patiently. The second restart can be used normally. The operating user is [root @ ok3568].
