meta-dynamicdevices

Common core for Dynamic Devices Yocto board support

Support for local kas build is a work in progress. Some notes:

• it is expected that kas-container is used for builds
• the lmp-dynamicdevices-base.yml file expects three persisent folders to be present and mapped outside the container
• there is a script kas-build-base.sh which sets up folders with permissions for the container to access

Board Support

NOTE: We're building an unsigned image for testing but there's an issue with the build process that requires you to copy your factory-keys folder and sub-directories to build/conf/factory-keys for now. If you see the error below this is the problem.

| make[2]: *** No rule to make target '/build/conf/factory-keys/opteedev.key', needed by '/build/tmp/work/imx8mm_jaguar_phasora-lmp-linux/optee-test/3.21.0-r0/build/ta/create_fail_test/c3f6e2c0-3548-11e1-b86c-0800200c9a66.ta'.  Stop.

Power

Note that USB-A does not provide enough power for the system e.g. when a speaker is operating. The unit should be powered from an appropriate USB-C adaptor.
