==== Prepare ====
*Cross-compiling Toolchain
Please refer to [https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fxavier_toolchain.html%23wwpID0ESHA this link] to install toolchain on your Host PC.
*L4T source code and Rootfs
You could use SDK Manager or [https://developer.nvidia.com/embedded/downloads directly download] to get source code.
*Setting Up the Environment
Assume SDK install directory is <TOPDIR>，source code is in $L4T_DIR/sources directory.
<code>export TOP_DIR=<absolute path to top dir;in my case is /home/xumm/nvidia/nvidia_sdk/JetPack_4.2.2_Linux_GA_P3448/></code>
<code>export L4T_DIR=$TOP_DIR/Linux_for_Tegra</code>
<code>export LDK_ROOTFS_DIR=$TOP_DIR/Linux_for_Tegra/rootfs</code>
<code>export ARCH=arm64</code>
<code>export CROSS_COMPILE=aarch64-linux-gnu-</code>
<code>export CROSS32CC=arm-linux-gnueabihf-gcc</code>
<code>mkdir -p $L4T_DIR/sources/kernel/out_kernel</code>
<code>export TEGRA_KERNEL_OUT=$L4T_DIR/sources/kernel/out_kernel</code>
<code>export NVIDIA_PATH=$L4T_DIR/sources/kernel/nvidia</code>
<code>export NANO_DTS_PATH=$L4T_DIR/sources/hardware/nvidia/platform/t210/porg/kernel-dts</code>
*Build default image, prepare L4T environment
<code>cd $L4T_DIR</code>
<code>sudo ./apply_binaries.sh</code>
*Download VEYE code for Jetson Nano
<code>cd $L4T_DIR</code>
<code>git clone https://github.com/veyeimaging/jetson_nano<nowiki/>.git</code>
<code>export RELEASE_PACK_DIR=$L4T_DIR/jetson_nano</code>
====Using the Prebuilt Binaries====
====Using the Prebuilt Binaries====
=====Installing the Kernel and DTS=====
<code>cd $RELEASE_PACK_DIR/binaries</code>
<code>tar -xzvf Image.tar.gz</code>
<code>sudo cp Image $L4T_DIR/kernel/ -f</code>
<code>sudo cp $RELEASE_PACK_DIR/binaries/tegra210-p3448-0000-p3449-0000-a02.dtb $L4T_DIR/kernel/dtb/tegra210-p3448-0000-p3449-0000-a02.dtb -f</code>
<code>cd $L4T_DIR</code>
====Flashing the Jetson Nano Development Kit====
====Flashing the Jetson Nano Development Kit====
The steps to flash the Jetson Nano™ development kit are as follows:
#Ensure a jumper is connected across J48 button header to enable DC power.
#Connect the micro USB cable to the Jetson Nano™ and host PC.
#Set the board to recovery mode, as mentioned in below steps:
a. Power OFF the board.
b. Connect the jumper pin to the pin 3 and pin 4 of the J40 button header.
c. Power ON the Jetson Nano™ development kit.
If the board is successfully changed to recovery mode, the Jetson Nano™development kit will be enumerated as an USB device to the host PC.
Run the following command to verify whether the board is in recovery mode.
<code>lsusb</code>
The output message appears as shown below.
<code>Bus 001 Device 102: ID 0955:7f21 NVidia Corp.</code>
4. Run the following commands to flash the Jetson Nano™ development kit from
your host PC.
<code>cd $L4T_DIR</code>
<code>sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1</code>
Note: Now, the entire micro SD on the Jetson Nano™ development kit will be erased. It will take about 10-30 minutes to complete depending on the host PC configuration.
5. Reboot and connect the Jetson Nano™ board to a monitor and keyboard to complete the OS configuration, once flashing is completed.
====Building from Source====
====Building from Source====
=====Build kernel=====
*patch code
<code>cp $RELEASE_PACK_DIR/sources/kernel/veye327/* $NVIDIA_PATH/drivers/media/i2c/</code>
<code>cp $RELEASE_PACK_DIR/sources/kernel/kernel_veye327_config $L4T_DIR/sources/kernel/kernel-4.9/arch/arm64/configs/tegra_veye327_defconfig</code>
*build
<code>cd $L4T_DIR/sources/kernel/kernel-4.9/</code>
<code>make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_veye327_defconfig</code>
<code>make ARCH=arm64 O=$TEGRA_KERNEL_OUT Image -j4</code>
Completed Image file is $TEGRA_KERNEL_OUT/arch/arm64/boot/Image，could be used for Flashing or Upgrading.
Install Image for Flashing:
<code>sudo cp $TEGRA_KERNEL_OUT/arch/arm64/boot/Image $L4T_DIR/kernel/ -f</code>
=====Build DTS=====
*patch code
<code>cp $RELEASE_PACK_DIR/sources/dts/kernel-dts/* $NANO_DTS_PATH/</code>
<code>cp $RELEASE_PACK_DIR/sources/dts/kernel-dts/porg-platforms/* $NANO_DTS_PATH/porg-platforms/</code>
<code>cp $RELEASE_PACK_DIR/sources/dts/kernel-dts/porg-plugin-manager/* $NANO_DTS_PATH/porg-plugin-manager/</code>
*build
<code>make ARCH=arm64 O=$TEGRA_KERNEL_OUT dtbs</code>
<code>cp $TEGRA_KERNEL_OUT/arch/arm64/boot/dts/tegra210-p3448-0000-p3449-0000-a02.dtb $L4T_DIR/kernel/dtb/</code>
Could be used for Flashing or Upgrading.
====Upgrading Kernel Image and Supplements====
====Upgrading Kernel Image and Supplements====
First，you should copy '''Image''' file to Jetson nano somehow. Use a U disk for example.
<code>sudo cp <path to your Image dir>/Image /boot/Image -f</code>
====Upgrading DTB File by Flashing from Host PC====
====Upgrading DTB File by Flashing from Host PC====
Burning process reference 4.3, burning commands is as below:
<code>cd $L4T_DIR</code>
<code>sudo ./flash.sh -r -k DTB jetson-nano-qspi-sd mmcblk0p1</code>
Power off after flashing finished.
