[edit] 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.
[edit] 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
$ cd ~/Linux_for_Tegra/ $ sudo ./applybinaries.sh
$ sudo cp ~/Downloads/zImage ~/Linux_for_Tegra/rootfs/boot/zImage $ sudo cp ~/Downloads/extlinux.conf ~/Linux_for_Tegra/rootfs/boot/extlinux/extlinux.conf
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 ./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
[edit] 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

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

$ cd ~/ $ ~/sdk_812_1.1.11_linux/demo-sample/PyGTK/demoSX12.py
[edit] Compiling the kernel modifications
Get the source of the kernel being used. The link is to R21.4 there may be newer versions
$ wget http://developer.download.nvidia.com/embedded/L4T/r21_Release_v4.0/source/kernel_src.tbz2 $ tar xf kernel.src.tbz2 $ zcat /proc/config.gz > ~/kernel/.config
