Detailed Description

CPU0 (M85) Secure world fallback for the trustzone_threadx_demo.

Tag

[Ring 6 / APP] {World: S}

Under normal execution, SystemInit runs ra8_trustzone_init which transitions the CPU directly to the Non-Secure world to run ThreadX.

If the transition fails, main() serves as a fallback.
