This page will guide you in using the Sensoray Model 2253 with the Toradex iMX6 development boards.
You will need a Linux host to cross-compile the driver and demo applications. You will need version 1.2.14 or later of the 2253 Linux SDK. After extracting the SDK, create another directory beside it called "toradex". In the "toradex" directory, create a file called "build.sh" containing the following script:
#!/bin/sh
set -x
DRIVER=`pwd`/../sdk_x53_linux_1.2.14/driver
if [ ! -d linux-toradex ]; then
git clone -b toradex_imx_3.10.17_1.0.0_ga-next --single-branch git://git.toradex.com/linux-toradex.git
fi
if [ ! -d gcc-linaro ]; then
FILE=gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf.tar.xz
if [ ! -f $FILE ]; then
wget http://releases.linaro.org/14.11/components/toolchain/binaries/arm-linux-gnueabihf/$FILE
fi
tar xf $FILE
ln -s gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf gcc-linaro
fi
export PATH=${PATH}:`pwd`/gcc-linaro/bin
export CROSS_COMPILE=arm-linux-gnueabihf-
export ARCH=arm
cd linux-toradex
if [ x$1 = xclean ]; then
git clean -d -f -x -q
fi
gunzip -c ../config.gz > .config
make oldconfig
make prepare
make scripts
#cp ../Module.symvers.colibri-imx6 Module.symvers
cp ../Module.symvers.apalis-imx6 Module.symvers
KDIR=`pwd`
make -C $KDIR SUBDIRS=$DRIVER clean
make -C $KDIR SUBDIRS=$DRIVER modules
You'll also need to copy a file from the board "/proc/config.gz" to the "toradex" directory. You'll also need "Module.symvers.apalis-imx6" or "Module.symvers.colibri-imx6" from Toradex support.
Now run the build script from a terminal in the "toradex" directory.
sh build.sh
Now build the demo programs from a terminal in the "sdk_x53_linux_1.2.14" directory.
cd ../sdk_x53_linux_1.2.14 make demo_armhf
If the overlay example is required, build it using the cross compiler in the "sdk_x64_linux_1.2.14" directory. (The ImageMagick libraries will not be used due to cross-compiling, resulting in styled fonts not being available.)
cd ../sdk_x53_linux_1.2.14/overlay ../../toradex/gcc-linaro/bin/arm-linux-gnueabihf-gcc -I ../driver overlay.c -o overlay
Now copy the whole "sdk_x53_linux_1.2.14" directory to the Toradex board, and run the following commands in the terminal (as root)
cd sdk_x53_linux_1.2.14/driver cp s2253.fw /lib/firmware/ mkdir -p /lib/modules/`uname -r`/extra cp s2253.ko /lib/modules/`uname -r`/extra/ depmod -a modprobe s2253
The driver is now loaded on the board, and should load automatically whenever the 2253 device is plugged in. You can check "dmesg|tail" to verify the driver is loaded and 3 V4L2 "/dev/video" nodes are created.
To run the "demo.py" demonstration program, you will need to install these python packages first:
opkg install \
python \
python-pygtk \
python-ctypes \
python-threading \
python-subprocess \
python-mmap
There is no "mplayer2" package, so the "preview" button in the demo will not work. Instead, preview can be done using gstreamer using this command:
gst-launch-0.10 v4l2src device=/dev/video0 ! 'video/x-raw-yuv,width=720,height=480,framerate=30000/1001' ! ffmpegcolorspace ! ximagesink
To record from the terminal, use "./capture" (use -h to see options) or read "README.txt" for examples.
