Hi all,
I am running tz_vmm run script on i.mx53qsb. I have LVDS display kit attached to the board. I want the Linux (non secure world) to be displayed on the LVDS while the Genode uses the serial console. I wonder if you could tell me how can i do this.
Thanks!

You have to adjust the partitioning of the devices btween secure world (Genode) and non-secure world (Linux). This is primarily done via the CSU (Central Security Unit) of this Freescale SoC. You can find the relevant configuration hardcoded within:
repos/base-hw/src/core/include/spec/imx53/trustzone/csu.h
just reset mostly all devices except the UART to belong to the non-secure world, and set the DMA channel of the GPU (line 222) to be unsecure. Remove the relevant patches of the Linux guest OS from this branch (I think the last 4 commits):
https://github.com/skalk/linux/commits/imx53-tz
and then re-build the Linux kernel and Genode scenario.

Hi Stefan,
Thanks a lot.
I have tried to configure and run the tz_vmm example according to your explanation, but only the Linux penguin is displayed on left corner of the LVDS display kit and then it hangs. As you mentioned, I removed the last four patches from this branch ( https://github.com/skalk/linux/commits/imx53-tz) and re-compiled the Linux kernel. I also changed the kernel cmdline argument value in genode/os/src/server/tz_vmm/imx53/main.cc file to *console=ttymxc0,115200 gpu_nommu video=mxcdi0fb:RGB666,XGA di0_primary ldb=di0*. I wonder if you could tell me what is missing?
Thanks!

Ok, that means Linux succeeds in using the LVDS display. When you write: "it hangs" do you get any message from the Genode side, e.g. a VM exception dump? Otherwise you need to inspect the Linux kernel messages, did you enabled earlyprintk, and removed the serial console redirection of the kernel messages within the kernel commandline parameters?

no VM exception dump if i disable the serial port (CONFIG_SERIAL_MXC and CONFIG_SERIAL_MXC_CONSOLE) in the Linux configuration file. FYI, i use imx53_android_deconfig in /arch/arm/configs for building the Linux kernel.

I changed the kernel commandline parameters to *"video=mxcdi0fb:RGB666,XGA earlyprintk di0_primary ldb=di0*" and also enable early_printk (CONFIG_EARLY_PRINTK=y ), but it still displays the Linux penguin logo on top left conner of the LVDS display, and hangs.

However, If i set the UART device as UNSECURED and enable the the serial port in the configuration file, the Linux boots properly without an error and i get a shell in the serial console.

BTW, is it possible to run the guest OS unmodified in the normal world while Genode in the secure world using this 'tz_vmm' run example? i have a prebuilt Android/Linux uImage for imx53 QSB from the www.freeescale.com.

I wonder that you do not see any kernel messages when not redirecting the kernel console to serial line. However, potentially your Linux setup boots successfully, but there the only TTY that is started refers to the serial console. At least if you use the unmodified initramfs archive of our i.MX53 TrustZone example setup this would be the case. So you have to unpack the initramfs, patch the init's configuration so that it will start a (login) shell on tty1.
If that does not help, you need to find out why the kernel does not show anything (kernel messages) on screen by setting up the same scenario without Genode with an unmodified Linux kernel and thereby tweaking the kernel/initramfs until you see the kernel messages on screen.

No it is not possible to run an unmodified kernel in the normal world. TrustZone is _no_ virtualization technology. The "guest" kernel always needs to be aware what resources it is able to access and which not. It is hard, or in general impossible to virtualize via trap-and-emulate. Please, have a look at our TrustZone article for further details, including our Android scenario:
http://genode.org/documentation/articles/trustzone
Currently, we do not have any out-of-the-box example scenarios for the i.MX53 QSB, which make use of TrustZone. Other examples are using either the i.MX53 SABRE Tablet, or the USB armory. For the latest, please have a look at the development story and presentation of Martin Stein:

I have managed to run the trustzone demo on USB Armory. Currently i am using the serial port to boot the demo. I want the Linux (non secure world) to be displayed on a separate device while the Genode uses the serial port. Is it possible to connect the USB Armory to external device such as keyboard and display? I have an external USB NIC card connected to the USB Armory using the host adapter and tried to check the network connection in the normal world (Linux) after i run the Trustzone demo, but the network card is not detected. How to connect to the internet using USB Armory?

Ok, obviously you redirect the bootconsole to serial line again. But did you see any boot messages when not redirecting and setting the kernel options that Martin mentioned? More importantly, what about my hint to inspect the initramfs you are using, whether the init process will spawn a tty on-screen at all? It's hard to follow you when not getting feedback regarding earlier questions.
Alternatively, you can provide a git branch containing the Linux version including your currently used configuration, and a Genode branch with your state including the run-script you are using (including the initramfs, you're using), so one can reproduce your results.
Regarding the I2C error in your kernel boot messages, I think something importantly for the I2C controller to work properly is missing in your kernel configuration (in our branch we gave control of it to Genode, so it was normal that the kernel could not succeed with it).

Have you set CONFIG_DEBUG_LL and CONFIG_TTY_PRINTK in your Linux config? AFAIK this is also needed for earlyprintk. When I want my Linux to be really verbose, I furthermore add "loglevel=10" to the command line.
Could you please see the attached kernel log messages and check for possible errors? because I am still getting only the Linux penguin on the LVDS display. there are some errors such as, *da9052_ssc_i2c 0-0048: 2 - da9052_i2c_read:master_xfer Failed!*
Ok, obviously you redirect the bootconsole to serial line again. But did you see any boot messages when not redirecting and setting the kernel options that Martin mentioned? More importantly, what about my hint to inspect the initramfs you are using, whether the init process will spawn a tty on-screen at all? It's hard to follow you when not getting feedback regarding earlier questions.
I have tried different options, but no luck so far.
Alternatively, you can provide a git branch containing the Linux version including your currently used configuration, and a Genode branch with your state including the run-script you are using (including the initramfs, you're using), so one can reproduce your results.
Please find my patches in the following branches (Genode, Linux and initramfs)
https://github.com/jonhedave/Genode/tree/genode https://github.com/jonhedave/linux/tree/linux https://github.com/jonhedave/initramfs/tree/initramfs
Regarding the I2C error in your kernel boot messages, I think something importantly for the I2C controller to work properly is missing in your kernel configuration (in our branch we gave control of it to Genode, so it was normal that the kernel could not succeed with it).
Regards Stefan
Thanks,
Do you have any other experiment for ARM TrustZone on imx53 QSB?
AFAIK, no. We have a Trustzone demo for the USB Armory currently for which you can find the Linux [1] and Genode sources [2] online. There are several topic branches in my Linux repo that correspond to the USB Armory port and document the problems that we solved in a more detailed way as the final branch. Furthermore, there is a github issue [3] were I documented parts of the development too.
I have managed to run the trustzone demo on USB Armory. Currently i am using the serial port to boot the demo. I want the Linux (non secure
world)
to be displayed on a separate device while the Genode uses the serial
port.
Is it possible to connect the USB Armory to external device such as keyboard and display? I have an external USB NIC card connected to the
USB
Armory using the host adapter and tried to check the network connection
in
the normal world (Linux) after i run the Trustzone demo, but the network card is not detected. How to connect to the internet using USB Armory?
Thank you in advance for your answers.
Cheers, Martin

As I've assumed Linux already succeeded with its boot process. The console messages and prompt was not shown, because the Linux Kernel configuration was missing "framebuffer console" support. Probably that is not needed for Android, but it is for the busybox initramfs setup. To simplify these kind of Linux problems debugging, I've integrated the para-virtual serial line driver we use for the USB armory. Have a look at my forks of your branches:
