Raspberry Pi 7 inch Touch Display
The official Raspberry Pi 7 inch Touch Display works on ROCK Pi 4.
Usage on Radxa official Linux system
Edit file /boot/hw_intfc.conf and uncomment the following lines. And then reboot the device.
#enable raspberry pi official 7 inch LCD support intfc:dtoverlay=raspberrypi-7-inch-lcd
For waveshare LCD, both display and touch are two spi devices.
Due to the hardware limitation with only one CS for spi1 of ROCK Pi 4, waveshare LCD only support display but touch.
Wavashare LCD works as a framebuffer device.
Model B v2
Update kernel(>=4.4.154-83) and rockpi4-dtbo(>=0.9) pacakge.
When use it , add the following lines to the hardware interface config file /boot/hw_intfc.conf :
intfc:uart4=off
intfc:spi1=on
intfc:dtoverlay=spi1-waveshare35b-v2
To install the required display support packages enter the following command lines:
$ sudo apt-get update $ sudo apt-get install xserver-xorg-video-fbdev
Backup and clean the contents of file, /etc/X11/xorg.conf.d/20-modesetting.conf. Then add the following lines to it:
Section "Device"
Identifier "Rockchip Graphics"
Driver "fbdev"
Option "fbdev" "/dev/fb1"
Option "DRI" "2"
EndSection
You need to checkout the device, "/dev/fb1" or "/dev/fb0".
Reboot ROCK Pi 4.
Model C
Update kernel(>=4.4.154-83) and rockpi4-dtbo(>=0.9) pacakge.
When use it , add the following lines to the hardware interface config file /boot/hw_intfc.conf :
intfc:uart4=off intfc:spi1=on intfc:dtoverlay=spi1-waveshare35c
To install the required display support packages enter the following command lines:
$ sudo apt-get update $ sudo apt-get install xserver-xorg-video-fbdev
Backup and clean the contents of file, /etc/X11/xorg.conf.d/20-modesetting.conf. Then add the following lines to it:
Section "Device"
Identifier "Rockchip Graphics"
Driver "fbdev"
Option "fbdev" "/dev/fb1"
Option "DRI" "2"
EndSection
You need to checkout the device, "/dev/fb1" or "/dev/fb0".
Reboot ROCK Pi 4.
