Download Ubuntu OS Images and Boot Firmware
Visit https://ubuntu.com/download/mediatek-genio and download the following two archives to your host PC:
- The Ubuntu OS image (Desktop or Server) of your choice. The following steps apply to both Ubuntu Desktop and Ubuntu Server.
- The boot firmware for your Genio EVK
Extract the Ubuntu image first, and then extract the boot firmware into the same directory. On Ubuntu host PC this can be done with the following commands:
1 | cd ~/Downloads |
1 | tar -xJvf genio-classic-desktop-2204-x01-20231005-133.tar.xz |
1 | tar -xzvf ubuntu-boot-firmware-genio-1200-evk-v23.1.3.tar.gz |
1 | mkdir ubuntu_adlink_mtk |
Copy the following files from the Yocto image to the ubuntu_adlink_mtk.
bl2.img
bootassets.vfat
fip-mt8195.bin -> rename it as fip.bin
lk.bin
u-boot-env.bin
u-boot-initial-env-lec-mtk-i1200-ufs-2022.10+gitAUTOINC+c58839fb0a-r0 -> rename it as u-boot-initial-env
Copy the following files from baoshan-classic-desktop-xxxx to ubuntu_adlink_mtk
ubuntu.img
ubuntu.json
firmware.vfat
Unzip the Firmware File
Create a mount point (directory):
1 | sudo mkdir /mnt/vfat |
Mount the .vfat file:
1 | sudo mount -o loop firmware.vfat /mnt/vfat |
This will mount the .vfat image to the /mnt/vfat directory, allowing you to view and modify its contents.
Create a directory called lec-mtk-i1200-ufs under /mnt/vfat/FIRMWARE/mediatek/.
Put all the Yocto device tree files (/build/tmp/deploy/images/lec-mtk-1200-ufs/devicetree/) into this directory (/mnt/vfat/FIRMWARE/mediatek/lec-mtk-i1200-ufs/).
Also, the lec-mtk-i1200-ufs--5.15.42+git0+a46a21ed7e-r0-lec-mtk-i1200-ufs-20241015034349.dtb file and rename it as lec-mtk-i1200-ufs.dtb.
Repack (Unmount) the .vfat file:
After modifying the files in the mounted directory, unmount the image and repack it.
Unmount the .vfat file:
1 | sudo umount /mnt/vfat |
