RSB-4810/ROM-5880 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 : [http://ess-wiki.advantech.com.tw/view/How_to_debug_RK3568 How_to_debug].

Press "ctrl + c" key before power up the device, until get the following information on debug console : 
<pre>Hit any key to stop autoboot: 0

If lvds panel is not the default format of rgb888_vesa, Must set lvds format :
<pre>fw_setenv lvds_format rgb666_vesa
or

 '''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.
<pre>fw_printenv | grep display
...
display0=hdmi-default
display1=edp-1366x768
...

== Using envtools in Debian/Android ==

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

Take “eDP+HDMI”for example :

{| border="1" cellpadding="1" cellspacing="1"
|-
| '''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.
