Prepare Image
- Build Yocto Linux image with your expected version (e.g. A0386)
- You can follow this SOP to build your Yocto image.
- Modify kernel to "Add commit to support the Ubuntu desktop version"
- Prepare Ubuntu image (e.g. A0362)
Mount image
- You can find Yocto image in${WORKSPACE}/build/tmp/deplay/image/${MC}, and copy to your ${WORKSPACE}.
$ sudo cp –a imx-image-${MC}-20230816082527.rootfs.wic.bz2 ${WORKSPACE}.
- Unpack rootfs.wic
＄sudo bzip2 -d imx-image-full-${MC}-20230814102331.rootfs.wic.bz2
- Create folders to mount
＄mkdir ubuntu yocto
＄mkdir ubuntu/rootfs yocto/rootfs
- Mount Yocto image and Ubuntu image Partition2
＄sudo losetup --show -f -P imx-image-full-imx8mprsb3720a1-20230814102331.rootfs.wic
＄sudo mount /dev/loop22p2 yocto/rootfs/
＄sudo losetup --show -f -P 3720A1AIM30UIVA0362_iMX8MP_4G_2021-11-29.img
＄sudo mount /dev/loop23p2 ubuntu/rootfs/
- Copy Yocto module to${WORKSPACE}, then you can find Yocto module in rootfs/lib
$ sudo cp -a yocto/rootfs/lib/modules/ /home/adv/
- Delete under Yocto rootfs all files, and replace to Ubuntu rootfs
$ sudo rm -rf yocto/rootfs/
$ sudo cd ubuntu/rootfs/
$ sudo cp -a bin boot dev etc home lib media mnt opt proc root run sbin srv swapfile sys tmp usr var ~/yocto/rootfs/
- Repalce with Yocto module
$ cd ~/yocto/roosfs/lib
$ sudo rm -rf modules/
$ sudo cp -a ~/modules ~/yocto/rootfs/lib/
- Enter target image root directory
$ sudo chroot rootfs/
