Hello Spenser,

There are 2 separate Graphics SDK packages for hard and soft float support.
If you use " http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/gfxsdk/latest//exports/Graphics_SDK_setuplinux_4_09_00_01_hardfp_minimal_demos.bin"
, you get hard float support.

>>   You must use a soft-float toolchain (ie Code Sourcery) as the binaries
   provided by the Graphics SDK are soft-float. (hard float is on the TODO
   list)


Which demos do not run ? Any logs ? I can come on IRC if help is needed,

>>   Some demos run, others do not.

regards,
Prabu

Subject: [Buildroot] [RFC v2 1/1] ti-gfx: add new package

This is WIP of adding the TI Graphics SDK to Buildroot

Current Status:
   Kernel Drivers load without errror.
   pvrsrvctl starts with no errors.
   Some demos run, others do not.
   gstreamer videotestsrc ! eglglessink does not work.

TODO:
   Install startup files for sgx core. 
   Create .pc files to simplify additional packaging.
   Hard Float Binaries
   Testing, lots of testing.

Additional Info:
   I've been using the 3.9.6-x3 tag of the kernel at 
   https://github.com/RobertCNelson/stable-kernel
by use of the
   LINUX_OVERRIDE_SRCDIR option.

   You must use a soft-float toolchain (ie Code Sourcery) as the binaries
   provided by the Graphics SDK are soft-float. (hard float is on the TODO
   list)

   To load the driver manually use the following:
      modprobe omaplfb
      modprobe bufferclass-ti
      pvrsrvctl --start --no-module
