Components

The Ubuntu 20.04 image for VisionSOM-8Mmini module is based on the following components:

• Linux kernel 5.4.47 released by NXP and patched by SoMLabs (https://github.com/SoMLabs/somlabs-linux-imx/tree/somlabs_ubuntu_2021_07)
• Stable Ubuntu 20.04.2 rootfs
• U-Boot 2020.04 (https://github.com/SoMLabs/somlabs-uboot-imx.git branch somlabs-imx_v2020.04_5.4.47_2.2.0)

Hardware configuration
