CodeSourcery Toolchain Installation
The RidgeRun evaluation SDK uses the Codesourcery toolchain for cross compilation. You need to download and install the Code Sourcery ARM toolchain before you can build the SDK.
DVSDK 4 Installation
In addition to the toolchain, it is necessary to install the TI's Digital Video Software Development Kit (DVSDK) package before installing the SDK. The evaluation SDK uses the DVSDK 4.02.00.06. The download and installation instructions are detailed below:
1. The dvsdk_dm365-evm_4_02_00_06_setuplinux binary file can be downloaded from TI's site.
Binary file name of DVSDK for DM368 Processor is : dvsdk_dm368-evm_4_02_00_06_setuplinux.
Binary file name of DVSDK for DM365 Processor is : dvsdk_dm365-evm_4_02_00_06_setuplinux.
2. Install it by executing the binary file with the following commands:
sudo chmod a+wrx dvsdk_dm368-evm_4_02_00_06_setuplinux
3. You will be asked for the Toolchain's path, you need to specify the path to the binaries' directory of the toolchain as is shown in the following image:
4. Install the DVSDK with the default configuration.
OR for CONSOLE mode you can try below command
./ezsdk_dm814x-evm_5_05_02_00_setuplinux --forcehost --mode console
During the EZSDK installation process you will be asked for the toolchain's path, assuming that you installed it on /opt, the path that you need to provide is /opt/codesourcery/arm-2009q1/bin.
Install other required packages
Usually the SDK will ask you to install any missing package it requires that is not already installed on your host machine. You can install them using the following command:
sudo apt-get install package_name
The following is the list of the required packages by the SDK:
It is possible you need to install some additional packages when some features require them, the SDK will ask you for this packages in the form of a error message as is shown below:
Checking for host packages required by the SDK build system: buildsystem (build-essential) is installed make (make) is installed ncurses (libncurses5-dev) is installed texinfo (texinfo) is installed >> minicom (minicom) is NOT installed perl (perl) is installed quilt (quilt) is installed dc (dc) is installed subversion (subversion) is installed curl (curl) is installed git (git-core) is installed autoconf (autoconf) is installed crypt-ssleay (libcrypt-ssleay-perl) is installed quilt (quilt) is installed libusb (libusb-dev) is installed perl-expect (libexpect-perl) is installed mono (mono-devel) is installed There are missing packages, please install them: apt-get install minicom make: *** [.oscheck] Error 1
Also required: GIT and subversion:
sudo apt-get install git sudo apt-get install subversion
Installing the SDK
If you purchased a Professional SDK please ignore the section 1.5.1 and jump to 1.5.2.
Install the EVAL SDK version
Once you have downloaded the tar file of the evaluation SDK you can untar it by running the following command:
tar -xvzf eval-sdk-dm36x-leopardtievm.tar.gz
You may find it convenient to untar the evaluation SDK more than once. For example, you might want one version to be unmodified and another version to be your working development directory. RidgeRun suggests you untar the SDK development directories in your $HOME/work/ directory. When you have more than one development directory installed, just remember to have the DEVDIR shell variable set properly. To set the DEVDIR shell variable use the `make env` command specified at RidgeRun_Irazu_SDK_User_Guide#Build_SDK
Install the Professional SDK version
When all the purchase process is done, RidgeRun will provide you a GitHub repository access. For that, the GitHub user ID and other information might be requested. Once you provide that information, you must clone the given repository URL, using the next command:
git clone email@example.com:RidgeRun/<customer>.git
This would have the proper <customer> space modified. With this, you will have the SDK installed on the directory you were when executed the clone command.
RidgeRun suggests you install the SDK development directories in your $HOME/work/ directory. When you have more than one development directory installed, just remember to have the DEVDIR shell variable set properly. To set the DEVDIR shell variable use the `make env` command specified at RidgeRun_Irazu_SDK_User_Guide#Build_SDK
Configuring, Build and Testing with the SDK
RidgeRun SDK can be easily configured using a menuconfig-like tool.
Configure the features you want to have in your board using:
First you goto the directory where you installed the sdk and further we call it as $devidr
You'll find that there are a lot of options you can choose according to your needs.
Creating a Bootable SD Card Image - With loopback file
Step 1: SDK Configuration for creating a SD Card Image:
1. On your SDK 'make config' menu, search for Installer Configuration and set:
Firmware deployment mode (Deploy all the firmware to an SD card) ---> (0x82000000) RAM address to load components [*] Flash SD card image into loopback file instead of real SD (256) Size of loopback device for SD card (in MB) Root Filesystem type for SD card (Extended 3 File system (ext3)) ---> (148) Minimal size of rootfs (MB) *** Install on SD card options *** (40) Size of U-Boot VFAT partition (in MB) *** NAND Flash memory map (Partitions sizes are given in blocks number) *** (32) Uboot partition size (25) Minimum kernel partition size (1600) Mininum file system partition size *** MTD Integration options *** [*] Configure Kernel MTD partitions with U-boot information (davinci_nand.0) MTD device name () MTD extra partitions
2. Go to 'File System Configuration' and choose:
->File System image target -> Secure Digital (SDCard) Card
Step 2: Building the SDK
Several packages are needed in order to compile the SDK. The SDK build process will let you know what packages are needed. While compiling you will be prompted to install them using sudo apt-get <packages>.
You can get a description of all the available commands for the SDK by running the following command into your SDK's installation directory:
It will show a list as the shown bellow:
RidgeRun Integrated Linux Software Developer's Kit Make targets: build - build kernel, target fs, bootloader kernel - build kernel fs - build target filesystem cmdline - build cmdline for target kernel (fs target does the same as well) bootloader - build bootloader config - allow SDK to be configured config_batch - attempt to configure without user interaction clean - delete all derived files env - Displays commands to run to setup shell environment coreconfig - Select toolchain, bootloader, and kernel (updates bsp/mach/Make.conf) doc - Generate the SDK API documentation into the documentation folder prelink - prelink the root filesystem install - Install all out of date images to target installbootloader - Install bootloader to target installmtd - Install uBoot MTD partition table installkernel - Install kernel to target installfs - Install file system to target installcmdline - Install uBoot kernel command line installbootcmd - Install uBoot boot command Make parameters: VERBOSE - set to 1 to output executing commands LOGFILE - set to built output filename U-boot Installer Parameters ($DEVDIR/installer/u-boot-installer) PORT - Host serial port to use for install HOST_IP - Host IP address to use for TFTP install FORMAT - Set to 1 to force SD card to be formatted FORCEINSTALL - Set to yes to force performing the requested install target ERASECHIP - Set to yes if you want to scrub the FLASH chip during bootloader installation Examples: make # same as 'make build' make VERBOSE=1 make installbootloader PORT=/dev/ttyUSB1
Set the PATH to include the toolchain and also set the DEVDIR shell variable
$(make env) # this is the same as using grave accents to execute the output from the command - `make env`
3. Compile the SDK:
4. Create the new image
Step 3: Copy the newly built image to the SD Card
5. Insert the sdcard to the host machine and find out its device partition for ex it will be /dev/sdb or /dev/sdc using 'df' command.
6. Unmount the SD Card
umount /dev/sdX -> replace 'sdX' with the device partition you found using 'df' command. for example it will be 'sdb' or 'sdc'
7. Goto $devdir/images folder
sudo dd bs=64M if=sdcard.img of=/dev/sdX -> replace 'sdX' with the device partition you found using 'df' command. for example it will be 'sdb' or 'sdc'
Step 4: Set up the boot dip switch in the leopard board and boot the board
9. Insert the sdcard with the image on to the leo board and
Set switch 2 of DIPSW1 to ON, 1 and 3 to OFF. This is SD card boot mode.
10. Power up the board, it will automatically erase the NAND flash, and burn UBL, u-boot, kernel and file system.
Below Steps are for Flashing the SD Card image directly in to SD card without loopback file
This method allows the SDK to write directly into the SD card. WARNING a wrong configuration may cause the SDK to write into a wrong device which may cause problems, formating wrong devices or loss of data, be sure to find out the device mounting point of the SD card.
1. Insert the sdcard to the host machine and find out its device partition for ex it will be /dev/sdb or /dev/sdc using 'df' command.
2. Unmount the SD Card
umount /dev/sdX -> replace 'sdX' with the device partition you found using 'df' command. for example it will be 'sdb' or 'sdc'
3. Please enable below configuration under 'Installer Configurations' from 'make config' of the SDK.
[ ] Flash SD card image into loopback file instead of real SD (/dev/sdX) SD device on Linux host (NEW)
a) Replace /dev/sdX with the device partition you found using 'df' command
b) Other configurations under 'Installer Configurations' will remains the same as mentioned in the previous section ( Step1 in 'Creating Bootable SD Card Image with filesystem using the SDK')
You will get below message on the run terminal when you run 'make install'. Please enter 'yes' to continue
At the above image the sd card was mounted at /dev/sdb in this case the SDK will be configured to write sdb, on your computer the SD could be mounted at other mount point.
Note : Boot Switch should be set for 'SDCard Boot' as per Step 4 in the previous section ( Step4 in the 'Creating Bootable SD Card Image with filesystem using the SDK - With loopback file')
WARNING the SDK will format the device at the specified mount point, configuring the SDK to format a wrong device may cause data loss, boot partition format or other serious issues.

Using GStreamer with the LeopardBoard DM36x EVAL SDK
You can combine the SDK and the LeopardBoard DM36x with the GStreamer's API in order to get powerful multimedia applications in an easy and faster way. Some examples of use of GStreamer to implement basic multimedia pipelines can be found at below links :
Activation of video capture modules
While configuring the SDK go to
Kernel configuration->Device drivers->Multimedia support->Video capture adapters
and activate the devices you desire.
For more details see Hardware setup - LeopardBoard DM365
Before running a capture pipeline you must be sure you have chained the video previewer, that could be done in two ways:
Currently the v4l2src element has a build in property called chain-ipipe which by default is set to true.
If you are not using v4l2src or you have disabled its chain-ipipe property you can chain it by using the ipiped application.
Setting up video components
The output and mode used for video playback/capture can be set during the SDK configuration process. The first step is to enter the configuration script:
Inside Architecture configurations select the options you desire on Video Output and Video Default Resolution.
Finally compile your changes and install
make make install
When you use the SDK to set your video output and resolution, the SDK build process creates $DEVDIR/images/cmdline with different kernel command line parameter settings. The table below shows the various video output settings for three of the common settings
|Video Output||DVI||Component||Composite||sysfs file|
When you boot your board the RidgeRun logo will be displayed, in order to display video the following commands must be executed:
Output volume modification
To increase/decrease the volume for audio playback (or other audio options) type
and modify as desired.
