RK3399 has 3 VPorts. 

RTENOTITLE

RSB-4810 surport 4 types display : eDP、LVDS、HDMI、MIPI. 

Note：

1. HDMI、eDP、MIPI MUST be set to port 0 and port 1.

2. LVDS MUST be set to port 1 and port 2.

3.  LVDS and MIPI are alternative.



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>
=><span style="font-size:smaller;"></span>

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

Note :

LVDS panel support 4 bus format: rgb666_vesa、rgb888_vesa、rgb666_jeida、rgb888_jeida.

If lvds panel is not the default format of rgb888_vesa, Must set lvds format : 

fw_setenv lvds_format rgb666_vesa
or
fw_setenv lvds_format rgb666_jeida
or
fw_setenv lvds_format rgb888_jeida

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 edp-1366x768 as default setting.

3. Check your configuration in Terminal or debug console. 

fw_printenv | grep display
... 
display0=hdmi-default
display1=edp-1366x768
...
LVDS Name Resolution
lvds-g070vw01
 800x480
lvds-g150xgel05
 1024x768

Using envtools in Debian/Android

Using envtools to setup envs in Debian/Android OS is very similar in uboot.

Take “eDP+HDMI”for example :

In uboot In Debian/Android
setenv display0 hdmi-default
 fw_setenv display0 hdmi-default
setenv display1 edp-1920x1080 fw_setenv display0 edp-1920x1080
saveenv
reset reboot

Note :

The tool "fw_setenv" will save envs automatically in Debian/Android OS, so it isn't necessary to saveenv manually.
