Hi all,
I was trying to run tz_vmm script over the imx6 platform. In which i have put Genode OS image (printf script) as a guest OS in the Normal world to test the switching between the Secure world to the Normal world. And the following is the output I am getting..
Starting kernel ...

The last message on the window is [init -> tz_vmm] and nothing happens after that.
Could you please let me know if this is the correct output?
Well, in general it looks good the whole guest scenario seems to succeed. I don't know why the last uncompleted message is printed, but it may be that at last some VM exception is caught by the VMM, but the UART driver gets corrupted, because you use the UART device from both world concurrently. However, in general the world switch seems to work as expected.
