AM335x Graphics SDK build

Actually, my ultimate goal is building projects based on the PowerVR SDK. Currently, I can get them to build, but they cannot open the display context on the target.

I get a different behavior if I build the project in Eclipse linking to an older version, 4_10_00_01. This version has a library directory XSGX that is missing from the 5_01_01_01 release. In this case, it cannot open an X display.

I need the 5_01_01_01 since this is the release that is included in the BeagleBone kernel build.

Please refer to the following TI wiki.

Thank you for your response.

I have been using and following the instructions on this page. When I get to the build steps, I run into the error.

Hi Ken,

Could you confirm the link below is where from download the Graphics SDK 5.01.01.01 to avoid confusion with the right sources:

http://downloads.ti.com/dsps/dsps_public_sw/gfxsdk/5_01_01_01/index_FDS.html

I suggest you to check all paths in the Rules.make file.

Are you using the Linux kernel from git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git as it is described at:

http://processors.wiki.ti.com/index.php/RN_5_01_01_01

And if it is true could you post the steps for building it?

Hello Tsvetolin

The first site is where I downloaded the graphics package.

I used the linux kernel build from 

https://github.com/RobertCNelson/ti-linux-kernel-dev

This was based on instructions from the eLinux wiki page

http://elinux.org/BeagleBoardDebian#Official_BeagleBoard.org_Images_for_shipping_with_BeagleBone_Black

I followed the steps for the SGX Drivers. I have tried to modify the build script to to build the Xorg support.

Currently, I have abandoned trying to build the SGX graphics and am using Qt for my applicaiton.

I am having more success with the Qt and am now trying to build and install ffMPEG support.

Thank you for your response. I may revisit the SGX build at a later time.

Hi Ken,

I see that you are using different kernel version then the recommended in the SDK 5.01.01.01 release notes.

And could you share which _defconfig you are using?

Hi Ken,

The release notes mentions that XORG isn't supported

"Xorg driver build (SUPPORT_XORG=1) not supported."

http://processors.wiki.ti.com/index.php/RN_5_01_01_01#What_is_not_supported

Thank you for this information. The question remains how the demos were compiled that are included in the package. If they are using another version of the Xorg, then I would be satisfied with that support.

Thanks again.

Ken

Sorry for the delay in response, I had a hard time finding the file. This is what the kernel build is using.

0675.sgx_defconfig.txt

To reiterate my response Franklin Cooper, I am not necessarily looking for the Xorg generated by this version of the graphics package, but for an Xorg support that I can use to successfully build the demo and other applications.

Thanks again

Ken

The Xorg binaries you mentioned are most likely left overs from previous releases and the errors you are seeing are likely not due to an incorrect version of Xorg being used but simply since it isn't supported at all. I would guess that the makefiles were edited in a way to insure that building Xorg support would fail.

Unfortunately I can't get assist in getting Xorg working since the package itself doesn't support it.
