At last, download the mali ddk from

install it in the target, but it seems that there is still no ddx
driver and Weston in the system
First of all let me clarify that Weston is included in Tizen:Common
images with Wayland.
Couple of months ago I tried to enable graphical acceleration for
Tizen:Common on A20-OLinuXino-MICRO with exactly the same Mali DDK for
Wayland but it didn't work out. Btw this reminds me that I have to give
it a try on Radxa Rock when I have free time during the next weekend :)
If you are playing with Wayland I recommend you to have a look at the
following article from Philippe Coval in which he explains how to fix
display issues and as a work-around to rely on the frame buffer support:
https://dockr.eurogiciel.fr/blogs/embedded/tizen-arm-images-to-renesas/
Please note that the article is about Renesas rcar but it is pretty much
the same process for other boards with ARM SoC.
Best regards,
Leon

Hi Marico,
enlightenment in tizen 3.0 common is an x window manager and it can't
support wayland display server yet.
Thus you need to start X server before running enlightenment if you
want to run enlightenment.

1. After flash the packages from the daily build to the platform, the

I didn't see "/dev/fb0" in the system, then should it be ok? And how
to fix the blank issue?
Are you using frame buffer or you have graphical acceleration enabled
on this board?
Recently I had a blank screen issue on Radxa Rock while I was using
Weston and wayland with frame buffer support and I solved by settings
the resolution with fbset before launching Weston.
2. It seems that in tizen3.0 we don't need X at all, and just use
wayland, right? And then I want to start enlightenment without X but
it failed.
Actually Tizen:Common 3.0 is available with Wayland or with X11.
Although Wayland is preferred. Have a look at the available images
here:
http://download.tizen.org/snapshots/tizen/common/latest/images/
The Tizen:Common with Wayland comes with Weston (a reference
implementation of a Wayland compositor) which is started by systemd
unit called display-manager-run.service. This services executes the
following command to start Weston:
/usr/bin/weston --backend=fbdev-backend.so -i0 --log=%h/weston.log
Best regards,
Leon
How should I add the parameter to "enlightenment_start" to start
wayland successfully?
BEST REGARDS
