------Compile the driver patch



Compile the kernel under 64 bit Ubuntu OS on Intel x64 PC. (Virtual machine is fine. We are using Ubuntu 16.04 64 bit OS)


Note: You don’t need to compile the driver patch if you use the driver files (Image, zImage and tegra186-quill-p3310-1000-c03-00-base.dtb) under Binaries folder directly.



1. Copy compile tool gcc-4.8.5-aarch64.tgz to /opt, and unzip it

   sudo tar zxvf gcc-4.8.5-aarch64.tgz

   

2. Copy kernel_src.tbz2 and two patch files to /usr/src

   sudo tar xpf kernel_src-tx2.tbz2

   sudo chown -R <user_name> kernel

   sudo chown -R <user_name> hardware

   patch -p0 < tri_streaming_imx274_base28.1_TX2_NV_dtbs_20171027.patch

   patch -p0 < tri_streaming_imx274_base28.1_TX2_NV_kernel_20171027.patch

Note: <user_name> is the user name of your Ubuntu OS. For example: sudo chown -R leopard kernel


3. Copy tx2.sh to /usr/src/kernel. 

   under /usr/src/kernel, do

   source tx2.sh



4. Create a work folder under /home:

   sudo mkdir /home/work

   sudo chown -R <user_name> /home/work

   

5. In "kernel/kernel-4.4" folder, run:



   make O=$TEGRA_KERNEL_OUT tegra18_defconfig

   make O=$TEGRA_KERNEL_OUT zImage

   make O=$TEGRA_KERNEL_OUT dtbs



You will get Image and zImage under /home/work/TX2/kernel/kernel_out/arch/arm64/boot and tegra186-quill-p3310-1000-c03-00-base.dtb under /home/work/TX2/kernel/kernel_out/arch/arm64/boot/dts.



------Setup the driver on TX2



1. Download the L4T R28.1 for TX2 from link below.



https://www.dropbox.com/sh/8p3kgws42csrulu/AADYMwGXYE2_qKjtPLVDawgta?dl=0



and follow below steps to flash the R28.1 image the TX2.

Set the TX2 to recovery mode

sudo tar xpf Tegra186_Linux_R28.1.0_aarch64.tbz2

cd Linux_for_Tegra/rootfs/

sudo tar xpf ../../Tegra_Linux_Sample-Root-Filesystem_R28.1.0_aarch64.tbz2

cd ..

sudo ./apply_binaries.sh


Copy and replace the tegra186-quill-p3310-1000-c03-00-base.dtb under Linux_for_Tegra/kernel/dtb



sudo ./flash.sh jetson-tx2 mmcblk0p1



Note: You can also download the Jetpack 3.1 (which includes the L4T R28.1) from Nvidia website and install it to TX2 if needed.


2. After boot up, Copy Image, zImage to TX2 /boot.

3. copy 4.4.38-tegra-leopard.tgz to TX2 /lib/modules

   sudo cp 4.4.38-tegra-leopard.tgz /lib/modules

   cd /lib/modules

   sudo tar zxvf 4.4.38-tegra-leopard.tgz

4. Copy camera_overrides.isp to TX2 /var/nvidia/nvcam/settings (if there is isp file)

   sudo chmod 664 /var/nvidia/nvcam/settings/camera_overrides.isp

   sudo chown root:root /var/nvidia/nvcam/settings/camera_overrides.isp

5. Reboot the TX2

6. Open a terminal and do "nvgstcapture-1.0”. You can will get live video output.


Note: Please make sure there is a camera on J3.



------Setup Argus software



Download the files from link below.



https://www.dropbox.com/s/0t6388fsiocuvz7/argus_R28.1.tgz?dl=0



1. sudo apt-get update

2. sudo apt-get install cmake

3. sudo apt-get install libgtk-3-dev

4. sudo apt-get install libjpeg-dev

5. sudo apt-get install libgles2-mesa-dev

6. sudo apt-get install libgstreamer1.0-dev

7. tar zxvf argus_R28.1.tgz

8. cd argus

9. mkdir build && cd build

10. cmake ..

11. make

12. sudo make install

13. Do "argus_camera --device=0”, “argus_camera --device=1” and “argus_camera --device=2”to get the video output. 



Note:

1. You can also use gstreamer commands to get video output. Below is an example.



gst-launch-1.0 nvcamerasrc fpsRange=“60.0 60.0" sensor-id=0 ! 'video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)I420, framerate=(fraction)60/1' ! nvtee ! nvvidconv flip-method=2 ! 'video/x-raw(memory:NVMM), format=(string)I420' ! nvoverlaysink -e 



2. If you have cooling system (fan), you can use below commands to turn on/off the fan.      

       1) switch to the root user.

          sudo su

       2) echo 255 > /sys/kernel/debug/tegra_fan/target_pwm   //turn on         

          echo 0 > /sys/kernel/debug/tegra_fan/target_pwm     //turn off


3. If the camera module you have include the IR switcher, you can use below commands to control the IR switcher.

       1) switch to the root user.

          sudo su

       2) echo d > /sys/kernel/debug/pca9570_a/pca9570            //J1 camera

          echo n > /sys/kernel/debug/pca9570_a/pca9570            

          echo d > /sys/kernel/debug/pca9570_c/pca9570            //J2 camera

          echo n > /sys/kernel/debug/pca9570_c/pca9570

          echo d > /sys/kernel/debug/pca9570_e/pca9570            //J3 camera

          echo n > /sys/kernel/debug/pca9570_e/pca9570

4. If there are any new drivers, we will add them into link below.
