The project is suspended. as I sold my OPI5 and may be replacing it with a Rock's SBC

Hardware Preparation

• Cables

  • USB to TypeC calbe
  • 5V 4A Power Supply
  • HDMI cable(Monitor)

• 500W+ ATX PSU

  • 24 Pin ATX Connectors(with Jumper)
  • PCI-E power cables x 2
  • Floppy 4 pins to SATA x 1(for riser)

• Monitor

• Linux PC

• Orange PI 5 Plus

• M.2 To PCIE x16 adapater

• Graphic Card

• SD Card(32GB+) with reader

Software Preparation

Flash Armbian to SD Card

1.download armbian img here

I choosed Orangepi5-plus_bookworm_legacy_5.10.160_minimal.img.xz

2.get balenaEtcher

download link

3.insert the sd card into PC via reader & flash the image Insert the SD card into the card reader and plug it into the USB port of your computer.

Flash from file>Select Target>Flash

4.insert the sd card into OrangePi-5-Plus's SD Card Slot

5.Boot into OS.

6.install necessary tools on OPI

sudo apt-get update && sudo apt update
sudo apt-get -y upgrade && sudo apt -y upgrade
sudo apt-get install -y armbian-config firmware-amd-graphics pciutils git pkg-config libpng-dev libgl1-mesa-dev build-essential iptables
# Boot into CLI
sudo systemctl set-default multi-user.target 
#extraargs=video=1920x1080@60
sudo nano /boot/armbianEnv.txt

# sudo apt-get update && sudo apt update && sudo apt-get -y upgrade && sudo apt -y upgrade && sudo apt-get install -y armbian-config firmware-amd-graphics pciutils git pkg-config libpng-dev libgl1-mesa-dev && sudo systemctl set-default multi-user.target 

7.Enable 3D Acceleration (Ubuntu variant only):

sudo apt-get install python3-launchpadlib
sudo add-apt-repository ppa:liujianfeng1994/panfork-mesa
sudo add-apt-repository ppa:liujianfeng1994/rockchip-multimedia
sudo apt update
sudo apt dist-upgrade
sudo apt install mali-g610-firmware rockchip-multimedia-config

8.blacklist amdgpu or radeon

sudo nano /etc/modprobe.d/blacklist-radeon.conf

# content is: 
blacklist radeon

sudo nano /etc/modprobe.d/blacklist-amdgpu.conf

# content is: 
blacklist amdgpu

9.rebuild soft link

sudo rm -rf /vmlinuz
sudo ln -s /boot/Image /vmlinuz

10.shutdown & take the SD card out,insert the sd card into PC via reader

5.10 Kernel & Modules

Build Kernel

on PC

sudo apt-get install u-boot-tools
git clone https://github.com/orangepi-xunlong/linux-orangepi.git
cd linux-orangepi
git switch orange-pi-5.10-rk3588
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- rockchip_linux_defconfig
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig

Device Drivers>PCI Support>PCI Express Port Bus support

Graphics Support>ATI Radeon & AMD GPU (Enable SI & CIK Support)

I disabled Realtek Wifi driver & Rockchip Wireless Lan Support in menuconfig( I use Intel's AX210)

make -j16 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- Image modules dtbs

Copy builit Kernel & install modules

go into linux folder

sudo env PATH=$PATH make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- INSTALL_MOD_PATH=/media/${USER}/armbi_root modules_install

sudo cp ./arch/arm64/boot/Image /media/${USER}/armbi_boot/Image
sudo cp ./arch/arm64/boot/dts/rockchip/*.dtb /media/${USER}/armbi_boot/dtb/rockchip
sudo cp ./arch/arm64/boot/dts/rockchip/overlay/*.dtb* /media/${USER}/armbi_boot/dtb/rockchip/overlay
sudo cp ./arch/arm64/boot/dts/rockchip/overlay/README.rockchip-overlays /media/${USER}/armbi_boot/dtb/rockchip/overlay

# sudo cp ./arch/arm64/boot/Image /media/${USER}/armbi_boot/Image && sudo cp ./arch/arm64/boot/dts/rockchip/*.dtb /media/${USER}/armbi_boot/dtb/rockchip && sudo cp ./arch/arm64/boot/dts/rockchip/overlay/*.dtb* /media/${USER}/armbi_boot/dtb/rockchip/overlay && sudo cp ./arch/arm64/boot/dts/rockchip/overlay/README.rockchip-overlays /media/${USER}/armbi_boot/dtb/rockchip/overlay

insert the SD Card into OPI,and power up
