Building

1. Clone this repository including all submodules
2. Download the Jetson Linux driver package and cross compiler from: Jetson Linux Downloads
3. Extract the driver package:

       tar -xf jetson_linux_r36*.tbz2

4. Extract the kernel headers from the driver package:

       cd Linux_for_Tegra/kernel/
       tar -xf kernel_headers.tbz2

5. Extract the cross compiler
6. Build the modules:

       export ARCH=arm64
       export CROSS_COMPILE=<path to cross compiler>/bin/aarch64-buildroot-linux-gnu-
       export KERNEL_SRC=Linux_for_Tegra/kernel/linux-headers-*-linux_x86_64/3rdparty/canonical/linux-jammy/kernel-source/
       make all 

7. Install the driver modules

       export INSTALL_MOD_PATH=<path to install directory>
       make install

Known limitations

• When using external triggers the NVIDIA v4l2 control override_capture_timeout_ms has to be set a suitable timeout value or -1 for a infinite timeout. Otherwise incomplete buffers with the error flag set might be returned due to a timeout while waiting for the image.
