===Build kernel(Jetpack4.x)===
===Build kernel===
For Jetpack version 4.x and for using MV series cameras under Jetpack version 5.x, the kernel needs to be compiled.
==== kernel patch for MV series ====
==== kernel patch for MV series ====
<code>patch -p1 < [path to]veye_mv_l4t_[version].patch</code>
<code>patch -p1 < [path to]veye_mv_l4t_[version].patch</code>
==== patch code ====
==== For Jetpack 4.x, the camera driver is compiled into the Image ====
===== patch code =====
<code>cp $RELEASE_PACK_DIR/drivers_source/cam_drv_src/* $NVIDIA_PATH/drivers/media/i2c/</code>
<code>cp $RELEASE_PACK_DIR/drivers_source/cam_drv_src/* $NVIDIA_PATH/drivers/media/i2c/</code>

<code>cp $RELEASE_PACK_DIR/drivers_source/cam_drv_src/Makefile_<ver> $NVIDIA_PATH/drivers/media/i2c/</code>
==== build ====
===== build =====
<code>cd $L4T_DIR/sources/kernel/kernel-4.9/</code>
<code>cd $L4T_DIR/sources/kernel/kernel-4.9/</code>
<code>make ARCH=arm64 O=$TEGRA_KERNEL_OUT Image -j4</code>
<code>make ARCH=arm64 O=$TEGRA_KERNEL_OUT Image -j4</code>
==== For Jetpack 5.x, there is no need to compile the camera driver into the Image ====
===== build =====
<code>cd $L4T_DIR/sources/</code>
<code>./nvbuild.sh -o $TEGRA_KERNEL_OUT</code>
==== Build completed ====
Completed Image file is $TEGRA_KERNEL_OUT/arch/arm64/boot/Image，could be used for Flashing or Upgrading.
Completed Image file is $TEGRA_KERNEL_OUT/arch/arm64/boot/Image，could be used for Flashing or Upgrading.
<code>sudo cp $TEGRA_KERNEL_OUT/arch/arm64/boot/Image $L4T_DIR/kernel/ -f</code>
<code>sudo cp $TEGRA_KERNEL_OUT/arch/arm64/boot/Image $L4T_DIR/kernel/ -f</code>
*For xavier，need sign the file
*For Xavier and Orin，need sign the file
<code>cd $L4T_DIR</code>
<code>cd $L4T_DIR</code>
<code>./l4t_sign_image.sh --file kernel/Image --chip 0x19</code>
<code>./l4t_sign_image.sh --file kernel/Image --chip 0x19</code>
===Build modules(Jetpack5.x)===
===Build modules(Jetpack5.x)===
For version later than Jetpack 5.x, non-MV series products, can compile the driver directly as modules to get the ko file. It is recommended to compile the driver directly on Jetson Board.
