Omnivision OV5647 image sensor

The Omnivision OV5647 is a CMOS image sensor with the following features:

• Automatic image control functions:
  • Automatic exposure control (AEC)
  • Automatic white balance (AWB)
  • Automatic band filter (ABF)
  • Automatic 50/60 Hz luminance detection
  • Automatic black level calibration (ABLC)
• Image quality controls: lens correction, defective pixel canceling
• CSI2 serial data output (MIPI interface 2 lanes)
• Support for output formats: 8-/10-bit raw RGB data
• Maximum image transfer rate:
  • QSXGA "Mpixel" (2592 x 1944): 15 fps
  • 1080p: 30 fps
  • 960p: 45 fps
  • 720p: 60 fps
  • VGA (640 x 480): 90 fps
  • QVGA (320 x 240): 120 fps

Enabling the Omnivision OV5647 Linux driver

Follow these instructions to build and install the kernel Image and device tree.

4. Download the kernel sources

JETSON_NANO_SOURCES=$(pwd)
wget https://developer.download.nvidia.com/embedded/L4T/r32_Release_v1.0/jetson-nano/BSP/Jetson-Nano-public_sources.tbz2 --no-check-certificate
tar -xvf Jetson-Nano-public_sources.tbz2 
cd public_sources/
tar -xvf kernel_src.tbz2

5. Apply driver patches

Before start building the kernel and dtb sources, apply the patch with OV5647 camera sources:

Copy the patches tarball into the sources directory, decompress the tarball and apply the patch with the commands:

mv 4.2_nano_ov5647.tar.gz $JETSON_NANO_SOURCES/public_sources
cd $JETSON_NANO_SOURCES/public_sources
tar -xvf 4.2_nano_ov5647.tar.gz
quilt push

6. Compile kernel and dtb

Follow the steps:

cd $JETSON_NANO_SOURCES/public_sources
CROSS_COMPILE=${HOME}/toolchain_bin_${VERSION}/${TOOLCHAIN_DIR}/bin/$CC_PREFIX
KERNEL_OUT=$JETSON_NANO_SOURCES/public_sources/build
KERNEL_MODULES_OUT=$JETSON_NANO_SOURCES/public_sources/modules
cd $JETSON_NANO_SOURCES/public_sources
make -C kernel/kernel-4.9/ ARCH=arm64 O=$KERNEL_OUT tegra_defconfig
make -C kernel/kernel-4.9/ ARCH=arm64 O=$KERNEL_OUT menuconfig
make -C kernel/kernel-4.9/ ARCH=arm64 O=$KERNEL_OUT CROSS_COMPILE=${CROSS_COMPILE} -j6 Image
make -C kernel/kernel-4.9/ ARCH=arm64 O=$KERNEL_OUT CROSS_COMPILE=${CROSS_COMPILE} -j6 dtbs
make -C kernel/kernel-4.9/ ARCH=arm64 O=$KERNEL_OUT CROSS_COMPILE=${CROSS_COMPILE} -j6 modules
make -C kernel/kernel-4.9/ ARCH=arm64 O=$KERNEL_OUT modules_install INSTALL_MOD_PATH=$KERNEL_MODULES_OUT

7. Flash Jetson Nano memory

This guide assumes that the user already have JetPack 4.2 installed. This link contains details about how to install JetPack 4.2: https://docs.nvidia.com/sdk-manager/download-run-sdkm/index.html

JETPACK_4_2 contains the directory where JetPack 4.2 was installed. Usually in.

~/nvidia/nvidia_sdk

So please do:

export JETPACK_4_2=$HOME/nvidia/nvidia_sdk/

Make sure the Jetson Nano is in recovery mode

cd ${JETPACK_4_2}/JetPack_4.2_Linux_P3448/Linux_for_Tegra 
# Copy kernel generated
cp $JETSON_NANO_SOURCES/public_sources/build/arch/arm64/boot/Image kernel/
# Copy device tree generated
cp $JETSON_NANO_SOURCES/public_sources/build/arch/arm64/boot/dts/tegra210-p3448-0000-p3449-0000-a02.dtb kernel/dtb/
# Copy new modules
sudo cp -a $JETSON_NANO_SOURCES/public_sources/modules/lib rootfs/
# Flash memory 
sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1
