There’s a few options out there to get a Mira camera board working with your Raspberry Pi.
Get a pre-built image from the ams website
This is pre-built image is bullseye OS (not for pi5) and works with all Mira image sensors. (220,050,016) Simply download and flash to SD with Raspberry Pi Imager.
For Mira220, I’ve upstreamed a driver to the raspberr pi kernel github repo. Libcamera changes reside in a fork Other Mira sensor drivers are not yet public, but available on request.
Start from a fresh Raspberry Pi 64bit image. Or, use Raspberry Pi imager to prepare an SD card for you. [recommended] rpi imager
OS customization is possible during flashing (users, wifi, ssh access ..)
Insert the SD card and boot the system.
According to this guide.
Use this branch:
git clone --depth=1 --branch rpi-6.12.y https://github.com/raspberrypi/linux
The below guide explains how to build the image on the pi itself, but you can also cross-compile on another system (advanced users)
Prepare the build dependencies:
sudo apt install bc bison flex libssl-dev make
cd into the folder you just cloned and prepare the build configuration:
cd linux
KERNEL=kernel8
make bcm2711_defconfig
make -j6 Image.gz modules dtbs
sudo make -j6 modules_install
sudo cp /boot/firmware/$KERNEL.img /boot/firmware/$KERNEL-backup.img
sudo cp arch/arm64/boot/Image.gz /boot/firmware/$KERNEL.img
sudo cp arch/arm64/boot/dts/broadcom/*.dtb /boot/firmware/
sudo cp arch/arm64/boot/dts/overlays/*.dtb* /boot/firmware/overlays/
sudo cp arch/arm64/boot/dts/overlays/README /boot/firmware/overlays/
Then, in the file /boot/firmware/config.txt - add this line at the bottom:
kernel=kernel8.img
sudo reboot
Libcamera is the ISP framework, and cooperates with the driver. Follow this guide.

ninja -C build
sudo ninja -C build install
These are some little helper applications to show a video stream.
sudo apt install -y cmake libboost-program-options-dev libdrm-dev libexif-dev
sudo apt install -y meson ninja-build
git clone https://github.com/raspberrypi/rpicam-apps.git
Navigate into the root directory of the repository:
cd rpicam-apps
For desktop-based operating systems like Raspberry Pi OS, configure the rpicam-apps build with the following meson command:
meson setup build -Denable_libav=enabled -Denable_drm=enabled -Denable_egl=enabled -Denable_qt=enabled -Denable_opencv=disabled -Denable_tflite=disabled -Denable_hailo=disabled
meson compile -C build
sudo meson install -C build
sudo ldconfig
Try it out!
