7 Conclusion

This article describes the fast boot method for the SITARA AM62Ax family of processors. After combining Falcon SBL, eMMC startup, kernel startup optimization, and user mode using the minimal boot script, the AM62A is capable of starting CMS in 2.5s, satisfying the fast-boot needs of applications such as CMS. This article explains in detail how to proceed with each step for quick replication.
