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	saveenv
reset	reset

Note :

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

LVDS Name	Resolution
lvds-g070vw01	800x480
lvds-g150xgel05	1024x768
lvds-g215hvn01	1920x1080

Enter U-boot interrupt mode

Connect device to debug port, and open debug console. 

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.
