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).

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.

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

You have seen this notice as you have enabled OTG driver for mx53 LOCO board
For mx53 loco board, the OTG function is unavailable due to hardware
limitation
So, Only one usb function (device or host) can be available for certain

Please config your kernel to disable OTG and the usb function you don't
want to use
And remain the other usb function you would like to use

Below OTG configs should be removed:
CONFIG_MXC_OTG, CONFIG_USB_OTG

Choose one of below configs for host or device function
But DO NOT choose them together
