dm3730-binaries (modules, kernel Execute the script: build_configure... for DM3730)sh<br>
omap3530-binaries (modules, kernel ... It will ask you for
OMAP3530) Copy target directory to your board asthe right processor platform:<br> <pre>
cd targetThis program will configure and build this softwarescp -r dm3730-binaries <remote_user>@<IGEP IP>Select your processor:
/home/<your_desired_directory>scp -r scripts <
remote_userA>
@DM3730, <
IGEP IPB>
OMAP3530 Please choose one. (default:
/home/<your_desired_directory> Also included you've the IGEP Xloader and the configuration file.DM3730)</pre>
Enter After that you're ready for copy it inside your IGEP board and go to gstreamer directory normally inside /usr/lib/gstreamer-0.10 and create two symbolic links from this directory to your files:<br>
cd /usr/lib/gstreamer-0All build binaries will reside inside the target directory under your selected platform, copy all the content inside your board.10
ln IGEP-s /home/<your_desired_directory>/csX-Loader and Linux kernel have self own howto about build and install it ...x64P
ln -s Inside target/home/<your_desired_directory>/libgstticodecpluginscript directory you can found some useful scripts.so
or copy the files directly as inside target directory location. = Memory Map =
