SDK 3d demos don't work

While building the SDK did you also build and install the separate Graphics SDK package? If not, follow the instructions here to build and enable the graphics sdk:

http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide

This will enable OpenGLES and allow you to run the 3d demos once again.

Thanks!  I'll give it a try tomorrow.

Hi,

I have tries several times, but am unable to build the Graphics SDK.

I get the following error:

The TI Linux SDK is installed at:

The TI Graphics SDK is installed at home/harmon/Graphics_SDK_4_08_00_01

The Graphics SDK Rules.make modifications are:

# Set home area (ex /home/user/) HOME=/home/harmon

# Set Target filesystem path ( ex /home/user/targetfs ) TARGETFS_INSTALL_DIR=$(HOME)/ti-sdk-beagleboard-05.05.00.00/targetNFS

What am I doing wrong?  The kernel builds and installs correctly.  I build U-Boot, byt don't know why this matters.  I don't see anything pointing to it.

That appears to be a typo in the code introduced in the newest version of the Graphics SDK. The enum in include/linux/workqueue.h specifies that it should be WQ_FREEZABLE rather than WQ_FREEZEABLE. Changing that should allow you to build the sdk.

that got me further, but I still see many errors:

It seems the 4.08.00.01 SDK release has not yet been verified on your platform. Please use the 4.06.00.02 release which can be found here:

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/gfxsdk/4_06_00_02/index_FDS.html

Or also in the Graphics_SDK_setuplinux_4_06_00_02.bin under the linux sdk install path.

Hi,

From your logs, it looks like you are using 3.3 kernel. For AM35x,37xx platforms the graphics SDK release has been validated against 2.6.37 kernel. You will find this information in README.pdf present in the graphics SDK release package or you can also refer to below release notes link which mentions about the kernel versions supported or used for validation-

http://processors.wiki.ti.com/index.php/RN_4_08_00_01#Kernel.28Linux_PSP.29_versions_supported_or_used_for_validation

You need to change omaplfb_linux.c (present under GFX_Linux_KM/services4/3rdparty/dc_omapfb3_linux of the graphics SDK release package) for compiling against 3.3 kernel. You need to use the linux kernel version checks (#if LINUX_VERSION_CODE < KERNEL_VERSION(3,1,0)) accordingly based on the supported APIs in the kernel you are using.

Please find the updated omaplfb_linux.c attached for reference.

You can either try this or use the 04.06.00.02 release as suggested by Dave. 04.08.00.01 is the latest release but not yet integrated into SDK whereas 04.06.00.02 is the last release that was integrated into SDK.

Thanks,

Prathap.

As suggested I installed the Graphics_SDK_setuplinux_4_06_00_02 version of the SDK.

I am able to build this version!!  Thanks!

However, I still can't run the 3d demos after making a new SDcard.

Is there an order to building the kernel and the graphics SDK?

AM37x SDK:

Make clean

make all

make install

Graphics SDK:

make clean

make all

make install

Is seems the Graphics SDK is putting its demos in /opt/gfxsdkdemos/ogles and the Matric GUI is trying to run an app from /usr/bin/SGX/demos/Raw.

Do I need to manually copy files? 

Success!

Running the omap-demo script seems to have done the trick.

I am a Linux newbe and didn't understand the bootargs configuration.

Is this a u-boot setting?  Should I use uEnv.txt?

Thanks for the help!

Hi,

Good to know that you could now successfully build & run the 3D demo.

Yes, bootargs configuration is a u-boot setting which can be done at the u-boot command prompt.  You can set the bootargs at u-boot command prompt for your platform as mentioned below -

http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide#Execution_instructions

Then you can issue the saveenv command at the u-boot command prompt to save the configuration so that next time when you reboot, this is picked up & no need to set it each time.

If you are using uEnv.txt , you can configure there itself.  The main thing required from a 3D demo(graphics) perspective is the configuration of vram related parameters in bootargs. This is required to allocate more buffer size when you use dual buffering mode. Otherwise there is no other special bootargs requirement from a graphics perspective.

Thanks,

Prathap.
