LPC55S69 : freertos_mpu_ns/s examples

Hello !

Looks like in this example, RTOS is running on nonsecure side and able to call "static" stubs on secure side.

Do you have more advanced examples or can you give some tip how to or even it possible at all :

- all tasks running in secure word

- some task running on secure side and some tasks on nonsecure side with IPC communication

- rtos running on nonsecure side, ISR handled on secure side and IPC (queue) from ISR can be send to nonsecure task ?

or what kind of configurations are possible ?

At list would be nice to know how ISR from secure side can notify nonsecure task ?

Regards,

Eugene
