Hello,first of all, thank you for all your kind advices.
I disabled suspend feature first, and my board doesn't get freeze. I will find what make it get freeze later.
Anyway, now I am struggling to enable the Tizen UI on my HDMI Monitor. It seems that I need to port libtbm and libtdm backends because my reference image is built with exynos backends.
As my CPU supports DRM, I am trying to replace them with libtbm-dumb and libtdm-drm. But it is hard to find reference images because most images in download.tizen.org uses its own backends for the SOC that they are running upon.
So could you tell me if is there any reference board or sample image that runs upon drm?

There were some complaints that my previous message was not readable in some clients; so I'm reposting this.
It appears that you've successfully booted the system up.
However, it went to sleep (suspend to RAM) after boot-up, which made you think the system is turned off (or not responsive).
I'd propose you to disable suspend-to-RAM capability until you configure all related changes.
