Build and Installation

• SDK Build Procedure:

1) Edit Rules.make file and set appropriate paths

2) Build SDK Using -

    $ make OMAPES=X.x (see make help for more info)

4) Install the SDK into File system using:

    $ sudo make OMAPES=X.x install 

(This copies the *.so and *.ko to file system pointed to by TARGETFS_INSTALL_DIR variable).

Note: In Case of AM389x/387x platforms Syslink and VPSS modules need to be built for Video/Display subsystem.
