Subject: Genode on iMX53 with TrustZone

Dear,

I’m writing this e-mail to ask you some questions to build and boot Genode with TrustZone into FreeScales iMX53 QSB.

According to the article in https://sourceforge.net/p/genode/mailman/message/33584768/, I could build and boot (maybe) Genode in my iMX53 board.
Through the serial, I only could see the log as bellow :

…
Starting kernel …

kernel initialized
Genode 15.02
init main() : — create local services —
…
[init -> tz_vmm] Start virtual machine…

After this log, I could see only blinking prompt.

This indicates that Genode is properly started but something is wrong with the Linux in the non-secure world. Either it fails in booting or it's output doesn't reach the UART you're listening on (the same that Genode uses).


Is this successful boot of Genode with TrustZone? 
If possible, can you provide me with successful log on iMX53 QSB?

Attachment [1] is a proper output of the 'tz_vmm' scenario on the i.MX53 Quick Start Board using a 'hw_imx53_qsb_tz' build dir.


Furthermore, I’d like to boot guest OS (normal world OS) after booting up Genode with TrustZone.
Is there any way for this?


The 'tz_vmm' test is exactly about that. It attempts to start a 2.6 Linux kernel (Freescale vendor adaption) in the non-secure world and allows it to use the same UART as Genode for serial user IO.

Make sure that you're using a build dir for 'hw_imx53_qsb_tz' and not for 'hw_usb_armory' although it's the same SOC. Can you please send me the content of your '$BUILD_DIR/etc/specs.conf'? Furthermore, are you trying or have you previously tried to use a self-build Linux/Initrd or have you just run 'tz_vmm' without any further preparation? To be on the safe side do 'rm $BUILD_DIR/bin/*' before building 'tz_vmm'.

Cheers,
Martin
