Seems I confused you with my explanation esp. with the terms I used.
If I'm writing about the *host* I'm referring to your development
machine (laptop) which hosts the build system, the source code, etc.
The *target* in your case is the i.MX53 QSB which will run Genode. As
you're interested in TrustZone I assume you will run Genode/base-hw,
i.e., hw_imx53_qsb_tz, and not Genode/Linux. The getting started
only covers Genode/Linux which you may try first on your laptop with
linux_x86. In this case host and target melt into the same machine.

The common development cycle with separate target hardware (i.MX53
QSB) is to edit the sources and build bootable images on your host.
Then, the image must be transferred to the target, e.g., by writing an
SD card. Then, you boot the target and examine the log output on the
USB-RS232 adapter.

Please also have a look at repos/base-hw/doc/hw.txt in the Genode
sources. If it comes to the preparation of the bootable SD card for
i.MX53 I don't feel prepared enough to guide you. Maybe one of the
more experienced ARM developers can help out in this regard.

Does this clarify your question?
