Compile OTA image
Checkout to OTA branch
cd sources/meta-advantech git checkout OTA
After create a new build machine
build recovery image
bitbake initramfs-debug-image
build minimal image with OTA functions
bitbake core-image-full-cmdline
Make OTA SDcard
dd image to SD card
dd if=core-image-full-cmdline-imx6qrom3420a1.sdcard of=/dev/sdc;sync
Generate update.zip
Taken rom3420 as an example:
cp sources/meta-advantech/meta-WISE-PaaS/recipes-ota/ota-script/files/ota-package.sh build-3420/tmp/deploy/images/imx6qrom3420a1/
- ota-package.sh
Usage: ota-package.sh [OPTIONS] Generate package file to be used for OTA update on Yocto Linux -b <file> Bootloader image file -k <file> Kernel or Boot image file -d <file> DTB (device tree) file -r <file> Rootfs image file -o <file> Output file -h Show help
So we run command as below:
./ota-package.sh -k zImage -d imx6q-rom3420-a1.dtb -r core-image-full-cmdline-imx6qrom3420a1.ext4 -o update.zip
Update Manually
cp update.zip /cache/
cd /tools/ /tools/do_update.sh update.zip Write recovery command ... Write BCB ... 0+1 records in 0+1 records out 14 bytes copied, 0.00918567 s, 1.5 kB/s Setup OK. Reboot to recovery image!
Then
reboot
After reboot , system will enter recovery image for updating system and reboot system

After updating system
/tools/do_update.sh result
it returns
OK
which means system updates successfully
