현재까지 v3.0.0 version으로 trusted mode booting으로 진행하였다. 이번 장은 basic mode로 실행해보려고 한다.
결론을 먼저 말하면, v2.0.0 이상 version에서는 basic mode로 부팅되지 않는다. ST에서 v2.0.0부터 trusted mode에 중점으로 update를 하면서 basic mode에 관한 update되지 않고 있다. STM32MP1 OpenSTLinux Starter Package만 봐도 v2.0.0부터 basic mode에 관한 내용이나 image file을 제공하지 않는다.
