1 Overview

This guide shows how to connect VEYE-MIPI-290/327 to Jetson Nano. Jetson Nano SDK Version is r32.2.1. We provide two ways to do so: Prebuilt Binaries or Source Code. Yes, It's Open Source!

VEYE-MIPI-290/327 is STARVIS camera module with ISP functions build in. It outputUYVY data using MIPI-CSI2. We provide V4L2 interface for video streaming apps , and Video Control Toolkits (which is Shell Script) to control the camera module directly.

2 Hardware Setup

Jetson Nano's CSI2 interface is compatible with Raspberry Pi，so both Mini Adapter Board and Adapter Board is supported. In addition，It need a 5V power.

3 System Setup and Configuration

Jetson Nano system setup, please refer to official document：get-started-jetson-nano-devkit.

Development Docs：https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-321/index.html

3.1 Setting Up the Environment

  • Host PC which runs Ubuntu 18.04/16.04(64-bit).  
  • NVIDIA® provided L4T release and corresponding sample rootfs for Jetson Nano™ development kit.  
  • A kernel image , device tree blob (DTB) file and module drivers for the VEYE-MIPI-290/327 camera. The release package contains a kernel binary (Image),DTB files and module drivers, which you can download and rebuild from source.
  • A jumper pin connected across J48 button header to enable DC power.
  • A USB cable (micro USB port) to plug into the recovery port of the Jetson Nano™
  • development kit.
  • Power cable (5V-4A) to power the Jetson Nano™ board.
  • Micro SD card must be connected to the J501 slot.
  • A jumper pin must be connected to the pin 3 and pin 4 of J40 button header.  

4 Firmeware Upgrade

4.1 Prepare

  • Cross-compiling Toolchain

Please refer to this link to install toolchain on your Host PC.

  • L4T source code and Rootfs

You could use SDK Manager or directly download to get source code.

  • Setting Up the Environment

Assume SDK install directory is <TOPDIR>，source code is in $L4T_DIR/sources directory.

export TOP_DIR=<absolute path to top dir;in my case is /home/xumm/nvidia/nvidia_sdk/JetPack_4.2.2_Linux_GA_P3448/>

export L4T_DIR=$TOP_DIR/Linux_for_Tegra

export LDK_ROOTFS_DIR=$TOP_DIR/Linux_for_Tegra/rootfs

export ARCH=arm64

export CROSS_COMPILE=aarch64-linux-gnu-

export CROSS32CC=arm-linux-gnueabihf-gcc

mkdir -p $L4T_DIR/sources/kernel/out_kernel

export TEGRA_KERNEL_OUT=$L4T_DIR/sources/kernel/out_kernel

export NVIDIA_PATH=$L4T_DIR/sources/kernel/nvidia

export NANO_DTS_PATH=$L4T_DIR/sources/hardware/nvidia/platform/t210/porg/kernel-dts

  • Build default image, prepare L4T environment

cd $L4T_DIR

sudo ./apply_binaries.sh  

  • Download VEYE code for Jetson Nano

cd $L4T_DIR

git clone https://github.com/veyeimaging/jetson_nano.git

export RELEASE_PACK_DIR=$L4T_DIR/jetson_nano

4.2 Using the Prebuilt Binaries

4.2.1 Installing the Kernel and DTS

cd $RELEASE_PACK_DIR/binaries

tar -xzvf Image.tar.gz

sudo cp Image $L4T_DIR/kernel/ -f

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

cd $L4T_DIR

4.3 Flashing the Jetson Nano Development Kit

The steps to flash the Jetson Nano™ development kit are as follows:

  1. Ensure a jumper is connected across J48 button header to enable DC power.
  2. Connect the micro USB cable to the Jetson Nano™ and host PC.
  3. 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.

lsusb

The output message appears as shown below.

Bus 001 Device 102: ID 0955:7f21 NVidia Corp.

4. Run the following commands to flash the Jetson Nano™ development kit from

your host PC.

cd $L4T_DIR

sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1

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.

4.4 Building from Source

4.4.1 Build kernel
  • patch code

cp $RELEASE_PACK_DIR/sources/kernel/veye327/* $NVIDIA_PATH/drivers/media/i2c/

cp $RELEASE_PACK_DIR/sources/kernel/kernel_veye327_config $L4T_DIR/sources/kernel/kernel-4.9/arch/arm64/configs/tegra_veye327_defconfig

  • build

cd $L4T_DIR/sources/kernel/kernel-4.9/

make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_veye327_defconfig

make ARCH=arm64 O=$TEGRA_KERNEL_OUT Image -j4

Completed Image file is $TEGRA_KERNEL_OUT/arch/arm64/boot/Image，could be used for Flashing or Upgrading.

Install Image for Flashing:

sudo cp $TEGRA_KERNEL_OUT/arch/arm64/boot/Image $L4T_DIR/kernel/ -f

4.4.2 Build DTS
  • patch code

cp $RELEASE_PACK_DIR/sources/dts/kernel-dts/* $NANO_DTS_PATH/

cp $RELEASE_PACK_DIR/sources/dts/kernel-dts/porg-platforms/* $NANO_DTS_PATH/porg-platforms/

cp $RELEASE_PACK_DIR/sources/dts/kernel-dts/porg-plugin-manager/* $NANO_DTS_PATH/porg-plugin-manager/

  • build

make ARCH=arm64 O=$TEGRA_KERNEL_OUT dtbs

cp $TEGRA_KERNEL_OUT/arch/arm64/boot/dts/tegra210-p3448-0000-p3449-0000-a02.dtb $L4T_DIR/kernel/dtb/

Could be used for Flashing or Upgrading.

4.5 Upgrading Kernel Image and Supplements

First，you should copy Image file to Jetson nano somehow. Use a U disk for example.

sudo cp <path to your Image dir>/Image /boot/Image -f

4.6 Upgrading DTB File by Flashing from Host PC

Burning process reference 4.3, burning commands is as below:

cd $L4T_DIR

sudo ./flash.sh -r -k DTB jetson-nano-qspi-sd mmcblk0p1

Power off after flashing finished.
