A Yocto layer to provide a basic Linux distribution for embedded platforms. It contains some common platform support stuff here.

Other layers required to build the system are:

• meta-openembedded: specifically, meta-oe and meta-filesystems
• meta-openamp
• meta-rauc
• meta-clang: Optional, to compile everything with clang. This is the only compiler that's tested with these.

First, select the distro sativa in your build configuration; then configure your build/conf/local.conf to use one of the following machines:

• stm32mp157a-dk1: STM32MP1 development board

You may specify custom machines based on the hardware supported here.

Additionally, you may wish to enable additional image features for debugging:

EXTRA_IMAGE_FEATURES = "debug-tweaks tools-debug"

Note that the flag to enable a read-only rootfs (read-only-rootfs) is not specified, as this causes some configuration (namely Dropbear) to get overridden such that the host key is not stored on the overlay in /etc, and instead a ramdisk.

Typically, you will build the core-image-base image flavor.
