@debian please note mipi-lcd works only in 4.9 legacy kernel
go to the /boot/env.txt
and below the HDMI configuration, make sure there is this line (if not exists, create it)
mipi_lcd_enabled=true
this should enable the lcd.
stay safe && good day!
I use 4.9.241 kernel for ubuntu grom 20.04 on vim3
I add mipi_lcd_enabled=true at /boot/env.txt
and sudo reboot
But mipi-lcd is still black and is not active.
try providing more power to board,
and don’t use sd-usb boot. it will not have the correct timing, and won’t give proper display output.
Okay. now I use sd-usb image. So I will try mmc-boot image.
And Could I know what code file for mipi-lcd in linux-khadas?
thanks a lot for you.
You don’t need to setup for LCD screen, it will be autodetected. But you need to remove the HDMI cable if you want to use the LCD.
Hi numbqq
I want to active mipi-lcd by modifying the device-tree.
What is the mipi code file in the linux code below, and can you guide me on how to use it with device-tree? (in ubuntu 20.04)
Which platform driver should be used and how to modify the device-tree?
I would also like to know if there is no other way to use sudo insmod mipi-lcd.
Thank you.
To use TS050, you don’t need to modify the code.
