This guide includes instructions and tips users should follow to get their DM365 Leopard Board to work with the RR Evaluation SDK. For this guide different commands need to be executed on the host machine and the target. Commands to be run on the Ubuntu host have a yellow background. Commands to be run on the Ubuntu target have an aqua background.


The e-mail received with the evaluation SDK installation links should have:

  • The SVN repository link.
  • The toolchain download link.
  • An username and password in order to access the download link for the toolchain.

CodeSourcery Toolchain Installation

New DM365 SDK 2011Q2 uses the Codesourcery toolchain for cross compilation. You need to download and install the toolchain before you can build the SDK.

In order to download and install the CodeSourcery's toolchain for the DM365 SDK 2011Q2 please see Code Sourcery ARM toolchain 2009q1-203.

Install other required packages

Usually the SDK will ask you to install any missing package it requires that is not 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:

  • autoconf2.59
  • libgtk2.0-dev
  • bison
  • flex
  • mono-devel
  • libexpect-perl
  • libusb-dev
  • curl
  • minicom
  • libtool
  • libncurses5-dev

Checkout SDK

With this SVN repository Linux from the email, check out a development directory from the repository:

mkdir -p ~/work
cd ~/work
svn co <repositoryLink> leo365

I put all my development directories in the work directory in my home folder. You can have more than one development directory installed, just remember to have the DEVDIR shell variable set properly.

Build 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>.

Configure the features you want to have in your board using:

make config

Set the PATH to include the toolchain and aslo set the DEVDIR shell variable

$(make env) # this is the same as using grave accents to execute the output from the command - `make env`

Compile the SDK:


Install bootloader, kernel, and target file system on LeopardBoard 365

Verify bootloader is active

First a minicom (or any other terminal emulator used) session must be opened in order to stop the booting process at the bootloader prompt:


Reboot the board and stop the autoboot when

Hit any key to stop autoboot: ...

is displayed. Then close your minicom session.

Save bootloader to target hardware

The next step is to install the bootloader on the target. Typically you only install the SDK bootloader once.

make installbootloader

Update target hardware with new images

Power cycle your target hardware, and install uboot environment / kernel / FS on the target (per your SDK configuration choices):

make install

Similar to the bootloader installation, to install the devdir on the target the booting process should be stopped at the bootloader prompt.

Updating your SDK

Since the SDK is in a SVN respository RidgeRun can periodically make updates to the contents. To have an up-to-date SDK the following command must be executed on the SDK root directory

make update

If, for any reason, modifications to any files that are included in a patch were made, the make update process won't be able to finish successfully. In order to override this the following command must be executed

make update FORCE_UP=1

Note that all changes previously made to these files will be lost.

Also, a debug functionality is implemented where all the executed commands will be displayed on the standard error (usually the same as standard output). To activate it use

make update DEBUG_UP=1

Of course, a combination of both options can be used

make update FORCE_UP=1 DEBUG_UP=1

A brief help menu explaining these features can be displayed using

make help

For SDK 2011Q2 and later versions it has been added a new target called make show_updates which will shows a list of all available updates with its detailed description.

SDK Hints

SD boot recover

If you brick your board, this can be recovered from an SD card. In order to make a bootable SD card you first need to have a successfully compiled SDK.

SD card preparation

1. Insert the SD card to the host port

2. Find out the device mounting point (e.g. /dev/sdd)

3. On your devdir root directory type:

make sd_boot_recover device=/dev/sdX

where sdX is your device mounting point.

Install Boot recovery files on SD card

1. Remove SD card from host and reinsert the SD card into host. This will cause your host to mount the VFAT file system on the SD card.

2. Type

make install sd_boot_recover

Boot from SD to recover NAND image

1. Set switch 2 of DIPSW1 to ON, 1 and 3 to OFF. This is SD card boot mode.

2. Power up the board, it will automatically erase the NAND flash, and burn UBL, u-boot, kernel and file system. The SD card recovery LeopardBoard 365 serial output will provide progress information.

Verify NAND recovery

1. Set all pos of DIPSW1 to OFF for NAND boot mode.

2. Connect serial cable to PC and power cycle the board (it should boot up). Insert the SD card to the board.

Your LeopardBoard 365 now contains the UBL, uboot, kernel, and file system that was originally shipped on LeopardBoard 365 boards.

Having this done the bootloader and devdir must be installed (check Installation for instructions).

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:

make config

Inside Architecture configurations select the options you desire on Video Output and Video Default Resolution.

Finally compile your changes and install

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
Resolution 720P-60 720P-60 NTSC
davinci_enc_mngr.ch0_output DVI COMPOSITE COMPONENT /sys/class/davinci_display/ch0/output
davinci_enc_mngr.ch0_mode 720P-60 720P-60 NTSC /sys/class/davinci_display/ch0/mode
davinci_display.cont2_bufsize 6291456 6291456 3145728
vpfe_capture.cont_bufoffset 6291456 6291456 3145728
vpfe_capture.cont_bufsize 6291456 6291456 6291456

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.

LeopardBoard 365 GStreamer Pipelines contains instructions showing examples to demonstrate the hardware is working.

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.

Video initialization

When you boot your board the RidgeRun logo will be displayed, in order to display video the following commands must be executed:

fbset -disable

Output volume modification

To increase/decrease the volume for audio playback (or other audio options) type


and modify as desired.

Using ipiped and AEW library

Ipiped is a D-Bus server for controlling and configuring the camera sensor, the dm365 video processor and the aew library. It usually works together with the auto white balance and auto exposure (aew) library in order to give a better control of the quality of the image captured.

You can find a Demo version of the AEW library in our EVAL SDK for DM365 2011Q2. This version is fully functional but has some demo features:

  • The library will darken you current image periodically.
  • After a while the AEW algorithm will stop working and you will get the capture with the last values configured by it, so you will need to restart your AEW algorithm in order to test it again.

You can find more about Ipiped and the AEW library at Auto exposure and auto white balance library

AEW Commands

In order to use Ridgerun's AEW demo a series of commands needs to be entered at the Leopard's console:

640x480 Video Playback

First you need to remove RidgeRun logo image from the screen

 fbset -disable

The screen will be plain white after the "fbset -disable" command

In order to use the Ridgerun's AEW Demo, first a config script for the 5Mp video sensor mt9p031 needs to be run:

 ipipe-client run-config-script dm365_mt9p031_config

This will chain ipiped, set the bayer-pattern and others.

Next, configure auto exposure:

 ipipe-client init-aew G EC S C 150000 15 50 640 480 50

This will configure the auto exposure as:

White balance: Gray world algorithm
Auto exposure: Electronic centric
Gain type: the sensor gain
Exposure metering method: center weighted metering
Time between algorithm adjustments: 200000 uS
Minimum frame rate: 15
Frame segmentation factor: 50
Width: 640
Height: 480
Center percentage: 50%

For more information about RidgeRun's AEW options:

 ipipe-client help init-aew

Other options are available, for example white balance can use retinex algorithm, Exposure can use: partial metering, average metering or segmented metering.

Recommended pipeline for video playback:

 gst-launch -e v4l2src chain-ipipe=false always-copy=false ! dmaiaccel ! video/x-raw-yuv,format=\(fourcc\)NV12, width=640, height=480, framerate=\(fraction\)30/1 ! dmaiperf \
 ! TIDmaiVideoSink sync=false accelFrameCopy=false videoOutput=composite videoStd=D1_NTSC&

640x480 Video Recording

Same as 640x480 video playback, but use the following pipeline:

 gst-launch -e -v v4l2src always-copy=FALSE chain-ipipe=false num-buffers=300 ! \
 'video/x-raw-yuv,format=(fourcc)NV12,width=640,height=480' ! dmaiaccel ! dmaienc_mpeg2 ! \
 dmaiperf ! mpegpsmux ! filesink location= test8003.mpeg

A file named: test8003.mpeg will be created, no video will be displayed in the composite output.

1280x720 Video Recording

Similar to 640x480 video playback, but instead of using:

ipipe-client init-aew G EC S C 150000 15 50 640 480 50


 ipipe-client init-aew G EC S C 150000 15 50 1280 720 50

Use the following pipeline:

 gst-launch -e -v v4l2src always-copy=FALSE chain-ipipe=false num-buffers=300 \
 ! 'video/x-raw-yuv,format=(fourcc)NV12,width=1280,height=720 \
 ' ! dmaiaccel ! dmaienc_mpeg2 ! dmaiperf ! mpegpsmux ! filesink location= test8003.mpeg

A file named: test8003.mpeg will be created, no video will be displayed in the composite output.

Using GStreamer with the LeopardBoard DM365 EVAL SDK 2011Q2

You can combine the SDK and the LeopardBoard DM365 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 LeopardBoard 365 GStreamer Pipelines - SDK 2011Q2.
