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 3.10.00

  • Support linux kernel 2.6.35.13-2
  • ISEE kernel 2.6.35.13-2
  • Update codec server to codecs-omap3530_4_02_00_00.
  • Added MP3 codec (decode).

Dependences

  • ISEE Toolchain poky-eabi-glibc-i586-arm-toolchain-sdk-3.2.1.tar.bz2
  • linux kernel 2.6.35.13-2 included with this package.
  • Ubuntu 10.10
  • Automake 1.7 and Libtool ( sudo apt-get install autoconf automake libtool )
  • SDK: alsa-dev_1.0.20-r1_armv7a.ipk (Now included inside the directory: tools/package).<span style="color: rgb(0, 0, 0);" />

Download

The package be available in the IGEPv2 download area.

01-ISEE_Products --> IGEPv2 --> SW_Tools_SDK --> igep_gst --> igep-dsp-gst-framework-3_10_00.tar.bz2

Download the package and uncompress this package as normal user in your desired directory (don't use sudo command for decompress this file)

How to Build

You should edit the file Rules.make and update package path and toolchain path.

Rules.make

Your igep-gst directory path:

WORKSPACE=/home/<YOUR_USER_PATH>/Projects/myigep/workspace/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_00

Your toolchain directory path:<span style="color: rgb(51, 102, 255);"

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

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

Now the kernel it's included with this package you don't need to change anything related to the kernel.

Select your right processor:

PLATFORM=o3530 (OMAP3530)

PLATFORM=dm3730 (DM3730)

Build & Clean

Build the framework:

cd /home/<YOUR_USER_PATH>/Projects/myigep/workspace/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_00
make

Clean the framework

cd /home/<YOUR_USER_PATH>/Projects/myigep/workspace/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_00
make clean

Build & Clean Manually

cd /home/<YOUR_USER_PATH>/Projects/myigep/workspace/igep-dsp-gst-framework/igep-dsp-gst-framework-3_10_00
make dsplink
make lpm
make cmem
make sdma
make codecs
make c6accel
make c6run
make

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

Build Manually 

$ make linux_kernel dsplink cmem lpm sdma codecs dmai gst_ti opengldemos

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

  • make clean (dsplink) not work properly and it's necessary to do a make dsplink_clean for ensure all it's compiled correctly and remove the kernel modules from the dsplink directory.
  • gstreamer plugin directory "gstreamer-ti_svnr884/src/gstticodecplugin_dm3730" must be removed the first installation time (manually).
  • Typo in Makefile. "linaro_linux" must be changed to "linux_linaro". Otherwise "make linux_kernel" fails.
