What is?

IGEP gst framework it's based on TI DVSDK. It's modified version for provide all DSP essential packages and the gstreamer DSP plugin for use it in IGEP platforms.

Changes From 2.00.10

  • Resolve Control + C incorrect DSPLink implementation
  • Upgrade GST plugin to SVN Revision 884 from 808.
  • Added a OMAPFB sink in gst plugin.
  • Added c6run_0_94_04_04 package
  • Added c6accel_1_01_00_01 package
  • Added SDK alsa-dev_1.0.20-r1_armv7a.ipk package for compile DMAI (tools/package)
  • Support for IGEPv2 Revision C with DM37xx and OMAP35xx
  • lpm added git support and add support for kernel 2.6.35
  • Support linux kernel 2.6.35.y and Linaro 2.6.35.y (default binary build included - 2.6.35-1010-linaro-omap)
  • Added target/exec_gst as gst launch example.
  • Removed dots from the package directory name.


Enviroment Changes

  • Code Generation tools it's now included inside the directory tools and the enviroment it's configured for use it.


Dependences

  • ISEE Toolchain poky-eabi-glibc-i586-arm-toolchain-sdk-3.2.1.tar.bz2
  • linux kernel 2.6.35.y and Linaro 2.6.35.y (default binary build included - 2.6.35-1010-linaro-omap)
  • Ubuntu 10.04 LTS.
  • Automake 1.7 and Libtool.
  • SDK: alsa-dev_1.0.20-r1_armv7a.ipk (Now included inside the directory: tools/package)


Prepare the Enviroment

It's a requisite configure your kernel properly for build this package: 

a) ISEE Kernel (git.igep.es)

source /usr/local/poky/eabi-glibc/environment-setup-arm-none-linux-gnueabi
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- igep0020_defconfig

b) Linaro Kernel (http://git.linaro.org/gitweb?p=kernel/linux-linaro-2.6.35.git;a=summary)

source /usr/local/poky/eabi-glibc/environment-setup-arm-none-linux-gnueabi
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- omap3_defconfig



c) Linaro Ubuntu Kernel (http://git.linaro.org/gitweb?p=ubuntu/linux-linaro.git;a=summary)

Create a new file with this content:



echo "Setting environment for armel cross-compile"
export ARCH=arm
export CROSS_COMPILE=arm-none-linux-gnueabi-
export PATH=/usr/local/poky/eabi-glibc/bin:$PATH
export DEB_BUILD_ARCH=armel
export DEB_HOST_ARCH=armel



Save it as file with the name enviroment 
source enviroment 
Enter in the linaro ubuntu directory and for build you should do:



>> cd ${linaro}
>> fakeroot/rules clean
>> fakeroot/rules binary-linaro-omap

Download

The package be available in the IGEPv2 download area.

How to Build

You should edit the file Rules.make for edit the package path, linux kernel and toolchain location.

Rules.make

Your igep-gst directory path:

WORKSPACE=/home/mcaro/Projects/myigep/workspace

Your kernel directory path:

OMAP3503_SDK_INSTALL_DIR=$(WORKSPACE)/kernel/linaro

LINUXKERNEL_INSTALL_DIR=$(OMAP3503_SDK_INSTALL_DIR)/linux-linaro-2.6.35

Your toolchain directory path:

CSTOOL_DIR=/usr/local/poky/eabi-glibc

CSTOOL_PREFIX=$(CSTOOL_DIR)/bin/arm-none-linux-gnueabi-

You have two options: build all or every package individually.

a) All packages

make

b) One package

make <package_name> 

make dmai

make gst

make dsplink 

...

For clean the build you should execute:

make clean

or

make <package_name>_clean

such: 

make dmai_clean

make dsplink_clean

make gst_clean

Install

Copy the "target" directory inside your IGEP board ( rcp * jdoe@192.168.2.1: )

Inside IGEPv2 board you should copy the gst plugin inside the plugins directory, normally inside /usr/lib/gstreamer-0.10

We included some files for configure, load and unload the kernel modules as loadmodules.sh and unloadmodules.sh

You should call the loadmodules.sh script before you can execute gstreamer.


Uboot Setup

You should configure the max kernel memory to 430MBytes for do it you should pass the variable mem=430M to the kernel. 

This is a suggested configuration:
bootargs-base=mem=430M console=ttyS2,115200n8 console=tty0 omapfb.mode=dvi:1280x720MR-16@60 vram=32M omapfb.vram=0:8M,1:16M,2:8M


Issues detected in this version

  • The path file cannot contain any "." dot due a xdctools BUG.
  • make clean (dsplink) not work properly and it's necessary to do a make dsplink_clean for ensure all it's compiled correctly.
