Hello Zhao Lingjun,

The M4 core is not supported by the OpenEmbedded build system and thus not officially part of the Yocto project. This is because OpenEmbedded does not yet have support for CPUs without and MMU. There have been some efforts but there is nothing enabled on the Community BSP or BSP Releases for the i.MX processors.

My apologies for the inconvenience!

Regards,
