Now I’ve finally come around to have my bootloader in a state that I am actually doing the context switch etc. and can boot from secure to unsecure.
But the FreeRTOS enabled application, which runs ok with disabled Trustzone, crashes while calling svc to start up the scheduler.
The following HardFault exception I get is back in secure state, which makes no sense at all to me since svc should be banked. Any ideas what I am missing?
EDIT: Ok, looks like this was a side effect from having the interrupts globally disabled before jumping to the application. Interestingly enough this was not a problem while starting from unsecure to unsecure. ( someone had a similar problem 10 month ago )
