Introduction

This page will guide you in using the Sensoray Model 1012 with NVIDIA tegra k1 development boards.

A modified kernel is required.

The modified kernel can be flashed onto the TK1 from the development PC, installed by the TK1 or the modifications can be made by the TK1 and recompiled.

The driver needs to be compiled with jetson=y.

Flashing a modified kernel image

This method uses pre-compiled images of Sensoray driver 1.1.9 and Linux for Tegra R21.4, improvements in later versions will not be present.

Get the modified zImage extlinux.conf and tw6869.ko files for Jetson Tegra K1 from Sensoray and put them in Downloads folder Follow Jetson quick-start guide from NVIDIA

quick-start step 1. Download Linux for Tegra package and sample root file system 

  $   wget http://developer.download.Jetson.com/embedded/L4T/r23_Release_v1.0/Tegra210_Linux_R23.1.1_armhf.tbz2
  $   wget http://developer.download.Jetson.com/embedded/L4T/r23_Release_v1.0/Tegra_Linux_Sample-Root-Filesystem_R23.1.1_armhf.tbz2

quick-start step 2. Untar and assemble the rootfs 

  $   sudo tar xpf ${RELEASE_NAME}
  $   cd Linux_for_Tegra/rootfs/
  $   sudo tar xpf ../../Tegra_Linux_Sample-Root-Filesystem_R21.4.0_armhf.tbz2
  $   cd ../

Modify the kernel to be flashed 

  $ sudo cp ~/Downloads/zImage ~Linux_for_Tegra/zImage
  $ sudo cp ~/Downloads/extlinux.conf ~Linux_for_Tegra/bootloader/ardbeg/jetson-tk1_extlinux.conf.emmc

Get the driver for Sensoray 1012. 

  $ sudo cp ~/Downloads/tw6869.ko ~/Linux_for_Tegra/rootfs/lib/modules/3.10.40-gdacac96/extra/tw6869.ko

Flash the TK1 (step 3. in Jetson's quick-start guide)

Put your target system into "reset recovery mode" by holding down the RECOVERY button and press RESET button once on the target main board.

Ensure your Linux host system is connected to the target device through the USB cable for flashing. 

  $ cd ~/Linux_for_Tegra/	
  $ sudo ./applybinaries.sh
  $ sudo ./flash.sh jetson-tk1 mmcblk0p1  #This will take less than 10 minutes.

from the TK1 load the Sensoray driver. 

  $ sudo depmod /lib/modules/3.10.40-gdacac96/extra/tw6869.ko
  $ sudo insmod /lib/modules/3.10.40-gdacac96/extra/tw6869.ko

Restart with Sensoray 1012 attached 

  $ sudo reboot

MPlayer is used by the demo 

  $ sudo apt-add-repository universe	
  $ sudo apt-get update
  $ sudo apt-get install libasound2-dev zlib1g-dev libxv-dev
  $ sudo apt-get install mplayer mencoder

Run the demo 

  $ wget http://www.sensoray.com/downloads/sdk_812_linux_1.1.9.zip
  $ unzip sdk_812_linux_1.1.9.zip
  password:<not included in this doc>
  $ ~/sdk_812_1.1.9_linux/demo-sample/PyGTK/demoSX12.py

Installing a modified kernel from TK1

This method uses a pre-compiled image of Linux for Tegra R21.4, improvements in later versions will not be present.

Get the modified zImage and extlinux.conf files for nVIDIA Tegra K1 and put them in Downloads folder

Install kernel modifications 

  $ sudo cp ~/Downloads/zImage ~/boot/zImage
  $ sudo cp ~/Downloads/extlinux.conf ~/boot/extlinux/extlinux.conf

Get Mplayer for the demo

Add universe repository 

  $ sudo gedit /etc/apt/sources.list

Uncomment the universe repository lines 

deb http://ports.ubuntu.com/ubuntu-ports / trusty universe
deb-src http://ports.ubuntu.com/ubuntu-ports / trusty universe
deb http://ports.ubuntu.com/ubuntu-ports / trusty-updates universe
deb-src http://ports.ubuntu.com/ubuntu-ports / trusty-updates universe

Save and exit

Install dependencies 

  $ sudo apt-get update
  $ sudo apt-get install libasound2-dev zlib1g-dev libxv-dev

Install MPlayer 

  $ cd ~/	
  $ wget http://mplayerhq.hu/MPlayer/releases/MPlayer-1.2.tar.xz
  $ tar xf ~/Mplayer-1.2.tar.xz
  $ cd ~/Mplayer-1.2
  $ ./configure
  $ make -j4
  $ sudo make install

Get the driver for Sensoray 1012. The listed link is for 1.1.11 there may be a newer version.

Version 1.1.11 from Sensoray 

  $ cd ~/
  $ wget http://sensoray.com/downloads/sdk_812_linux_1.1.11.zip
  $ unzip sdk_812_linux_1.1.11.zip
  password: <not included in this doc>
  $ cd /usr/src/linux-headers-3.10.40-gdacac96
  $ sudo make modules_prepare


Load the driver 

  $ cd ~/sdk_812_1.1.11_linux/driver/vbuf2	
  $ make jetson=y
  $ sudo make install
  $ sudo make load
