I follow steps in this link: https://sourceforge.net/p/genode/mailman/message/33588666/. The system  can boot successfully ,but after the linux started，it periodically print this message:

Have you tried to boot plain Linux, at best the Linux version from
Freescale we used as the base? Does it print the same? Have you tried
to put another SD-Card into it?

Actually, I have no idea why the sd-card controller's hardware
interrupt is not triggering when you use the unmodified Genode version
with the Linux binary provided by the tz_vmm.run script.
