RSB-4710 surport 4 display ports : eDP、LVDS(mipi to LVDS)、HDMI、DP (DP to HDMI). Only two ports work at the same time .

You can config Multi-Display to eDP + HDMI 、eDP + LVDS、LVDS + HDMI 、eDP + DP、LVDS + DP、HDMI + DP.

NOTE:

        Android distinguish the primary and the extend screen. 

Enter U-boot interrupt mode

Connect device to debug port, and open debug console. See more : How_to_debug.

Press "ctrl + c" key before power up the device, until get the following information on debug console : 

Hit any key to stop autoboot: 0
=> <INTERRUPT>
=>

Then you can input the following cammand to config Multi-Display.

NOTE : 

1. The name of the panel must begin with "edp-"、"lvds-" 、"hdmi-"  or “dp-”.

And it can be found in "kernel/include/dt-bindings/display/screen-timing/{LCDNAME}.dtsi" like :

lvds_g070vw01: lvds-g070vw01

2. If there is no configuration, you will get default setting :

hdmi-default  and dp-default as default setting.

3. Check your configuration in Terminal or debug console.

cat /proc/cmdline
... prmry_screen=hdmi-default extend_screen=dp-default

Setenv in Debian (or Android) OS

Envtools are supported in debian and android os. You can change envs in Terminal or debug console very similarly in uboot.

Take "eDP + HDMI" for example:

IN uboot In Debian/Android
setenv prmry_screen hdmi-default fw_setenv prmry_screen hdmi-default
setenv extend_screen edp-1920x1080
fw_setenv extend_screen edp-1920x1080
saveenv
reset reboot

NOTE : 

Tool of fw_setenv will automatically save env, so it isn't neccesary to save it manually.
