3 Upgrade Jetson Nano, TX2,Xavier and Orin system

3.1 Overview

This section describes how to upgrade the Jetson system to support our camera module.

  • Jetpack4.x versions

To support our camera module, we need to update the two parts of the L4T (Linux for Tegra) of the Jetson system, Image and DTB.

In the Image, we added the camera driver, while the DTB indicates the camera model used. In general, you only need to use the Image and DTB, that we have prebuilt, and you don't need to build from source when it is not necessary.

  • Jetpack5.x versions

The driver is no longer compiled into the Image, but loaded into the system as a separate module. The dtb file is still compiled together as a whole to facilitate replacement.

The dtb can also be loaded dynamically as an overlay. Refer to the official nVidia Developer's Guide for NVIDIA® Jetson™ Linux for details.

  • For MV series camera

For MV series modules, we have added features to Image in order to support extended data types and external trigger modes. So regardless of Jetpack version, you need to update Image.

Whether you need to update modules depends on Jetpack version.

3.2 BSP package introduction

3.2.1 Path

https://github.com/veyeimaging/nvidia_jetson_veye_bsp

3.2.2 bsp package includes:
  • prebuilt dtb for different boards
  • driver source code
  • dts source code
  • i2c toolkits

In release packages

  • prebuilt linux kernel:Image
  • prebuilt camera drivers

3.3 DTB file corresponds to Jetson boards

3.3.1 Nano A02

tegra210-p3448-0000-p3449-0000-a02.dtb

3.3.2 Nano B01

tegra210-p3448-0000-p3449-0000-b00.dtb

3.3.3 Nano 2GB

tegra210-p3448-0003-p3542-0000.dtb

3.3.4 TX2 Devkit

tegra186-quill-p3310-1000-c03-00-base.dtb

3.3.5 TX2 NX(p3509-0000 carrier board)

use the same carrier board with XAVIER NX Devkit

tegra186-p3636-0001-p3509-0000-a01.dtb

3.3.6 AGX XAVIER

tegra194-p2888-0001-p2822-0000.dtb

3.3.7 XAVIER NX Devkit

tegra194-p3668-all-p3509-0000.dtb

Specially, For Jetpack5.x, must use this dtb:

  • Jetson Xavier NX (P3668-0000) For developer kit only:

tegra194-p3668-0000-p3509-0000.dtb

  • Jetson Xavier NX (P3668-0001) Commercial module:

tegra194-p3668-0001-p3509-0000.dtb

3.3.8 AGX Orin

tegra234-p3701-0000-p3737-0000.dtb

3.4 DTB file name and camera module correspondence

Under the dtb directory of each motherboard, the directory corresponding to the camera model is stored, and you can usually know the corresponding camera model directly by the directory name.

Specially:

1, VEYE-MIPI-CAM2M is the new version of VEYE series dtb, which supports all VEYE 2M series products, including VEYE-MIPI-327E, VEYE-MIPI-IMX327S, VEYE-MIPI-IMX462, VEYE-MIPI-IMX385.

2, The ones with fpdlink as suffix correspond to fpdlink coaxial model module.

3.5 Upgrade directly on the jetson board

Applicable models: Jetson Nano, Xavier and Orin.

Note: AGX Xavie Jetpack version >= 4.4 , support this upgrade mode. Earlier versions have not been verified and are not recommended.

3.5.1 Check the current L4T version

First check the current L4T version and try to replace it with the same version.

cat /etc/nv_tegra_release

If it shows:

# R32 (release), REVISION: 4.3......

It means L4t Verion is 32.4.3

3.5.2 Note about L4T 32.7. 2

The Image and dts of L4T 32.7.2 are identical to those of L4T 32.7.1, so you can directly use the contents of the L4T 32.7.1 related directory.

In addition, the upgrade requires updating cboot, please refer to the FAQ section.

3.5.3 Download the bsp package to the Jetson board

On Jetson Board:

wget https://github.com/veyeimaging/nvidia_jetson_veye_bsp/releases/latest/download/nvidia_jetson_veye_bsp.tar.gz

Or type in the address bar of your browser:https://github.com/veyeimaging/nvidia_jetson_veye_bsp/releases/latest/download/nvidia_jetson_veye_bsp.tar.gz

tar -xzvf nvidia_jetson_veye_bsp.tar.gz

3.5.4 Upgrade Image(For Jetpack4.x or MV series cameras)

Backup old version Image

cp /boot/Image /boot/Image.backup

cp /boot/Image.sig /boot/Image.sig.backup

Under the bsp package directory, find the corresponding version of the Image package, decompress it, and execute:

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

For Xavier NX Devkit

Need to use the signed file(For example,file inside Image_l4t_r32.*.*_veyecam_signed_4_xavier),copy Image and Image.sig to /boot/ dir on the Jetson Xavier board:

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

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

Effective after restart.

3.5.5 install camera modules(For Jetpack5.x)

Check linux version:

uname -r

Find the corresponding directory in nvidia_jetson_veye_bsp/ko :

sudo cp nvidia_jetson_veye_bsp/ko/$(uname -r)/* /lib/modules/$(uname -r)/kernel/drivers/media/i2c/ -f

3.5.5.1 General

Register the modules to the system by executing the following command.

sudo depmod

3.5.5.2 Special

If using a camera module with fpdlink interface. You must manually control the loading order to ensure that ds90ub954.ko is loaded before the camera driver is loaded.

After the system boots, manually insert the drivers in order, e.g.

sudo insmod ds90ub954.ko

sudo insmod cs_imx307.ko

The command to load the driver can be added to the startup script.

3.5.6 Upgrade dtb

Under the bsp package directory, find the dtb file corresponding to your camera module model and L4T version number.

sudo mkdir /boot/veyecam/

sudo cp <path to your dtb dir>/<DTB file name> /boot/veyecam/ -f

Backup extlinux.conf file first

cp /boot/extlinux/extlinux.conf / boot/extlinux/extlinux.conf.back

Then, edit the /boot/extlinux/extlinux.conf file and add the following line.

FDT /boot/veyecam/<DTB file name>

Note: <DTB file name> should be replaced with the corresponding dtb name of the mainboard, ensure that the file specified in the FDT line actually exists correctly.

Effective after restart.

3.6 Upgrade Jetson Board using Host PC

This section provides the second method of upgrading the system.

This method has the same goal as the method in the previous section, and one of the two can be chosen.

This method is complicated and not recommended for Nano, Xavier, Orin.

Specifically, for TX2 systems, only the methods in this section can be taken to upgrade.

3.6.1 Burn the standard Image

Note: if your Jetson board has correctly burned the standard version Image, you can skip this step.

You can burn the standard Image using SDK Manager or following the steps below.

  • Set PATH

Assume SDK install directory is <TOPDIR>.

export TOP_DIR=<absolute path to top dir accroding to your jetpack version and board name;for example /home/xumm/nvidia/nvidia_sdk/JetPack_4.5_Linux_JETSON_XAVIER_NX_DEVKIT/>

export L4T_DIR=$TOP_DIR/Linux_for_Tegra

  • Build default image, flashing to Jetson Board, prepare L4T environment

cd $L4T_DIR

sudo ./apply_binaries.sh  

- Nano

sudo ./flash.sh jetson-nano-devkit mmcblk0p1

sudo ./flash.sh jetson-nano-2gb-devkit mmcblk0p1

You should be able to find the camera model you used.

3.7.2 For Image

ls /sys/bus/i2c/drivers/

When installing the camera correctly, the relevant directory for the camera should exist, such as veyecam csx307 cssc132 mvcam, etc.

3.8 Protection against being overwritten by upgrades

After making sure Image and dtb are successfully updated, please execute the following command to prevent kernel and dtb from being overwritten by update.

sudo apt-mark hold nvidia-l4t-kernel nvidia-l4t-kernel-dtbs

3.9 Build the drivers from source

Please refer to: Nvidia Jetson platform VEYE camera driver source code compilation guide.

Could be used for Flashing or Upgrading.

The [i2c_bus] in the driver prompt message indicates the i2c bus corresponding to this camera.

4.2 Video Stream Toolkits Manual

The camera appears as /dev/videoX device node,where X is between [0-5].

During the Linux boot process, the cameras are detected in the order of i2c bus from smallest to largest. For example, if only one camera is connected, X is 0 regardless of the hardware connection to the location. If 5 cameras are connected, X is reflected as [0-4] according to i2c bus from smallest to largest.

In gstreamer command ,v4l2src and nvv4l2camerasrc has a param device=/dev/videoX to identify which camera to use.

4.2.3 Jetson multimedia-api samples

The Jetson Linux API is available on the Jetson platform for developers to use. Please refer to the official nVidia documentation for the installation of the jetson_multimedia_api package.

For VEYE and CS series cameras, the ISP function is already integrated in the camera, so you cannot use libargus to get data, but can directly use the standard V4L2 interface to get data from the /dev/videoX device file.

The following two samples can be run directly.

4.2.3.1 12_camera_v4l2_cuda

./camera_v4l2_cuda -d /dev/video0 -s 1920x1080 -f UYVY

4.2.3.2 v4l2cuda

./capture-cuda -d /dev/video0 -f UYVY -m -o out.ppm -s 1920x1080 -c 1

4.2.4 v4l2-ctl Application Examples
4.2.4.1 install v4l2-utils

sudo apt-get install v4l-utils

4.2.4.2 Configure parameters using v4l2-ctl
  • List the data formats supported by the camera

v4l2-ctl -d /dev/video0 --list-formats-ext

  • Frame rate statistics

v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=UYVY--stream-mmap --stream-count=-1 --stream-to=/dev/null

  • Save image to file

5 How to port the driver to a third party board

5.1 driver porting

For Image, we have added functionality to the official standard Image and have not made any deletions. In general, you can use our compiled Image directly. for special cases, please refer to the source code for integration.

For modules it is even easier to just use them. Compiling from source code and is very simple, so I won't go into details here.

5.2 dts porting

We only provide dtb for some boards of Nano, TX2, Xavier, Orin. For the types not provided, it is necessary to:

1. get the dts source code of that board.

2. put our camera related dts to the whole.

3. recompile to get the dtb of the corresponding board.

The operation steps are not complicated, but there are some third-party base board manufacturers do not open dts source code. This will require the cooperation of all parties to do so.

6 FAQ and bug list

6.1 VEYE cameras on Jetpack5.x

Jetpack5.x has more stringent requirements for mipi signals in xavier and orin platforms. VEYE-MIPI-xxx series cameras need firmware hdver>=7 to be perfectly supported.

6.2 Jetpack5.0.1 DP

This version has many bugs, such as not supporting nvv4l2camerasrc, not recommended to use.

6.3 nv3dsink

Jetpack 5.x no longer supports nvoverlaysink, use nv3dsink instead.

6.4 cboot of L4T32.7.2 on Xavier

For the Xavier series, there is a bug in the cboot of L4T32.7.2 that must be fixed before the upgrade can be done.

[Cboot] Cboot in 32.7.2 fails to read extlinux.conf

We compiled the correct version of cboot and put it here.

After downloading, put it in Linux_for_Tegra/bootloader directory and execute the following command on PC to burn cboot.

  • AGX Xavier

sudo ./flash.sh -r -k cpu-bootloader jetson-xavier mmcblk0p1

  • Xavier NX

sudo ./flash.sh -r -k cpu-bootloader jetson-xavier-nx-devkit mmcblk0p1
