Disclaimer
The IMX390 is a sensor for automotive. RidgeRun can help you extending the driver as needed but the customer needs to be sure that they qualify as an automotive client for Sony in order to get access to the sensor documentation and provide it to RidgeRun. Otherwise, RidgeRun would be blocked on providing support.

Enabling the driver
Follow these instructions to build and install the kernel image and device tree.
1. Install dependencies
2. Set the environment variables for the sources L4T 31-1-0
3. Install the toolchain
4. Download the kernel sources
5. Apply driver patches
Before start building the kernel and dtb sources, apply the patch with IMX390 camera sources:
Copy the patches tarball into sources directory, decompress the tarball and apply the patch with the commands:
XAVIER_SOURCES=$(pwd) mv 4.2_d3_ds90ub960_imx390.tar.gz $XAVIER_SOURCES/sources cd $XAVIER_SOURCES/sources tar -xvf 4.2_d3_ds90ub960_imx390.tar.gz quilt push
6. Compile kernel and dtb
Follow the steps:
cd $XAVIER_SOURCES/sources
CROSS_COMPILE=${HOME}/toolchain_bin_${VERSION}/${TOOLCHAIN_DIR}/bin/$CC_PREFIX
KERNEL_OUT=$XAVIER_SOURCES/images/build
KERNEL_MODULES_OUT=$XAVIER_SOURCES/images/modules
cd $XAVIER_SOURCES/public_sources
make -C kernel/kernel-4.9/ ARCH=arm64 O=$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=$KERNEL_MODULES_OUT
7. Flash Xavier
This guide assumes that the user already has JetPack 4.2 installed. This link contains details about how to install JetPack 4.2: https://docs.nvidia.com/sdk-manager/download-run-sdkm/index.html
JETPACK_4_2 contains the directory where JetPack 4.2 was installed. For example.
export JETPACK_4_2=$HOME/JetPack-L4T-4.2
Make sure the Xavier is in recovery mode
cd ${JETPACK_4_2}/JetPack_4.2_Linux_P2888/Linux_for_Tegra
# Copy kernel generated
cp $XAVIER_SOURCES/images/build/arch/arm64/boot/Image kernel/
# Copy device tree generated
cp $XAVIER_SOURCES/images/build/arch/arm64/boot/dts/tegra194-p2888-0001-p2822-0000.dtb kernel/dtb/
# Copy new modules
sudo cp -a $XAVIER_SOURCES/images/modules/lib rootfs/
# Flash memory
