Hi everyone,
I have two questions during testing the tz_vmm on i.MX53 QSB.
1. I want to set up the TrustZone environment like switching between SW and NW on Android in NW on top of Genode in SW, but don't know what I should do exactly. Do you have any manual or advice for this? Which part should I look into?
2. How can I test switching the two worlds on the tz_vmm?
Any help appreciated.
Thank you!
Regards, Daeyoung

I assume you want to reproduce the same demo scenario we presented on the i.MX53 SABRE Tablet in this video [1]? If this is the case, you've first to develop an input driver for the touchscreen of the i.MX53 Quickstart Board, which is in contrast to the SABRE Tablet not yet available. The whole setup, as well as how to reproduce that scenario on the SABRE tablet can you read in this article [2]. If you've more specific questions regarding the scenario, feel free to ask them.

If you run the automated run test 'tz_vmm' that can be found in Genode's mainline repository, you don't have to do anything to test the world switch, the test is fully automatic, and if it succeeds the world switch worked perfectly. That test is not meant for demonstration purposes to switch manually between one world and the other, but it starts a Genode system including a TrustZone "normal world monitor", which boots a Linux kernel giving it access to almost all hardware resources e.g.: Ethernet card, and serial line. The Linux kernel boots till the end, and the automated run script instructs Linux' command prompt to access Genode's website via 'wget'. If the page was loaded correctly, the test succeeds. During this process a lot of world-switches between the secure world (Genode), and the normal world (Linux) occur, e.g.: each time a timer interrupt used by the scheduler of Genode's hw-kernel occurs. Of course you can extend the 'tz_vmm' run script to start more applications on the Genode side to see that part in action in parallel.

Any help appreciated.

OK, I see. I will ask them later.

Yes, I made a simple application to test it.
Now I understand clearly this. Thanks again.
