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.

Default Support Display
| Port | RSB4810 |
| edp | edp-1920x1080 edp-1366x768 |
| lvds | lvds-g070vw01 lvds-g150xgel05 |
| hdmi | hdmi-default |
| mipi | mipi-gl0uan |
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
| 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 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 :
The tool "fw_setenv" will save envs automatically in Debian/Android OS, so it isn't necessary to saveen manually.
