Hi all,

I am trying to enable Trustzone features for i.mx6 saberlite board in OS. At this stage, I am stuck with a problem.

I am not able to locate Normal world RAM address to load second OS.

so some one help me to configure NORMAL and SECURE mode RAM address.

Thanks in Advance,

Chirag :smileyhappy:

Yes , I have gone through these links..

Actually I have enabled the switching b/w the Normal and Secure world. So when it is switching from secure world OS to the Normal world OS. It is giving IO mapped failed error. so i guess RAM configuration for Normal World is not correct.

so i need RAM configuration for Normal world in imx6 saberlite board.

Thanks in Advance,
