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.
