i.MX53 QSB and TrustZone

Hi guys,


I'm exploring the i.MX53 QSB and the TrustZone extensions.  I run an OS in the secure world thanks to the U-Boot bootloader. Now I'm in the secure world. I have three questions :

- The first question is when should I share the memory and the interrupts between the secure and normal world ?
- The second one is how can I move to the normal world in order to run a Rich OS on it?
- The third question concerns the monitor mode code, where should I write it ? Is it a kernel module in the secure world ?


Thank you in advance
