Hi,
Have a look at section "World switch between non-secure world and secure world" in http://genode.org/documentation/articles/trustzone. There it says "Given this approach, the software stack running in the secure world must not execute the smc instruction. This drastically simplifies the assembler world-switch routine."
Best.

Hi all,
I have some doubts in Genode Flow, ARM provides the smc instruction to enter in the monitor-mode which performs the world switch between normal world and secure world.
As tz_vmm script is also successfully achieving the above objective of world switch from the secure world to the normal world. But i am not able to figure out flow which will which execute a call of smc instruction in the run of tz_vmm script.
Can anyone explain me the flow ?
Thanks in advance.
