jdi screen driver

support debian 11 32-bit and debian 12 64-bit with raspberry pi, and debian 12 64-bit with orange pi zero 2w

Raspberry PI

Install

binary

• remove old jdi-drm

  sudo vi /boot/config.txt   
  # /boot/firmware/config.txt for debian 12
  sudo vi /etc/modules 
  sudo rm -f /boot/overlays/jdi-drm.dtbo 

• remove old sharp-drm in apt if exist, and other packages depend on it.

• unzip file to /var/tmp/jdi-drm-rpi

• cd to /var/tmp/jdi-drm-rpi

• run sudo make install

• reboot

from source

• orangepi

sudo dpkg -i /opt/linux-headers-next-sun50iw9_1.0.0_arm64.deb
sudo orangepi-add-overlay sharp-drm.dts
make all
sudo cp sharp-drm.ko /lib/modules/6.1.31-sun50iw9/
sudo depmod -a
echo "sharp-drm" | sudo tee -a /etc/modules

• raspberry pi

  sudo apt-get install raspberrypi-kernel-headers
  make
  sudo make install

Control backlight by side button

• put back.py in place like /home/username/sbin/back.py
• chmod +x back.py
• sudo crontab -e
• append @reboot sleep 5;/path/to/back.py
• if it doesn't work in debian 12 64-bit, reinstall python3-rpi.gpio

Set dithering level

echo <level> | sudo tee /sys/module/sharp_drm/parameters/dither > /dev/null
<level> from 0 to 4, 0 for close dithering, 4 for max

Orangepi zero 2W

Based on Orangepizero2w_1.0.2_debian_bookworm_server_linux6.1.31.7z

unzip jdi-drm-orangepi-debian12-64.zip file in any location and cd into it.

install

sudo orangepi-add-overlay sharp-drm.dts
sudo cp sharp-drm.ko /lib/modules/6.1.31-sun50iw9/ # when upgrade, only need copy this file and reboot
sudo depmod -a
sudo echo "sharp-drm" >> /etc/modules 
# make sure only one sharp-drm in /etc/modules
