AM3358: Graphics SDK of am3358

Hello LIANG,

Can you make debug build and retry? Also remove all the modules from /lib/modules/ before installing the new ones.

BUILD=debug

and it stop update since 2015 ,why?

I also copy the  tisdk-rootfs-image-am335x-evm.tar.gz in  my /home/root folder of my nfs filesystem ,

which is released in 201306 of am335x-evm-sdk-bin-06.00.00.00,then I unpack it ,

it is as following ,I insert the two module it seem fine.

but when I run the tool in my nfs ~/usr/bin/

it output nothing ,then end.

Hello Wangl,

We do not support gfxsdk anymore and please refer to our latest PSDK. I found an old thread with a similar issue and please refer to the following thread.

Hello Krunal:

Is there any doc ,how to build custom qt5 with opengl support  uing the new TI sdk,such as TI SDK V03_03_00_04?

when I build the Qt5.5.1 meet the problem

Hello,

We use the Yocto Project to integrate Qt into our PSDK and here are a couple of links to get you familiar with Yocto:
1. http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Overview_Building_the_SDK.html
2. https://training.ti.com/customizing-yocto-for-production-packagegroups

Here is an image that describes all the recipes we have modified for Qt:

I found that  on https://doc.qt.io/archives/qt-5.6/embedded-linux.html

 some devices require vendor-specific adaptation code for EGL and OpenGL ES 2.0 support.

This is not relevant for non-accelerated platforms, for example the ones using the LinuxFB plugin, which is meant for software-based rendering only. 

so  export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0 should be wrong.

so I change export environment as following

but when I run the opengl_demo  from the following

www.trentreed.net/.../

But it report that 

root@DR02:~# ./0_OpenGLWindow

EGL Error : Could not create the egl surface: error = 0x3005

what is wrong?

Dear Krunal:

The man in OGLES2ChameleonMan run very fast.on my machine

It is only Qt problem,not related to Graphics_SDK .

Best regards

wangl

Hello,

As mentioned in the following document, TI SDK integrates many open source software but we do not own, maintain and support all the packages. Please post Qt specific questions on Qt forms.

QT Framework

• https://www.qt.io
• https://doc.qt.io
• https://forum.qt.io

Also, please try running the Qt out of box examples included in the folder "/usr/share/qt5/examples" of the TI filesystem.

Regards,
Krunal

Dear Krunal:

Hello Wangl,

I am wondering if you could please download the latest PSDK from the following link. In the TI file-system, we have pre-built Qt examples under the following directory: "/usr/share/qt5/examples". I am able to run the examples without any problems.

Regards,
Krunal
