LPC55S69 : cmse_nonsecure_entry privileges

Hello !

 

I have FreeRTOS tasks on non secure side what running with user privileges.

Sometimes the should use cmse_nonsecure_entry calls to secure side and it is not so clear with what privilege this call appears on secure side.

 

I think call with user privilege on nonsecure side should be with user privilege on secure side as well.

Or some escalation of privileges can happens or can be done ?

 

Regards,

Eugene
