PVRShell: Unable to create surface

Satyaprakash Mishra

Hello Friends

Am getting below error on my Beaglebone-DVID when am trying to run 3D application from from Graphics_SDK_4_08_00_01.

root@am335x-evm:~/pen/ogles# ./OGLESEvilSkull
Can't open keypad input device (/dev/input/event0)
Can't open remote control input device (/dev/ttyS1)

IPVRShell: EGL 1.4 initialized
Failed to create egl window surface with a 0 ews window handle.
This is probably caused by running a NWS application with ews_wsegl module in use.
Failed to create egl window surface with a 0 ews window handle.
This is probably caused by running a NWS application with ews_wsegl module in use.
Exit message has been set to: "PVRShell: Unable to create surface
".
InitAPI failed!
PVRShell: Unable to create surface

All generic application is working fine. for EX : sgx_init_test / sgx_render_flip_test / ......etc

Any help will be greatly appreciated.

Thanks!

What is the Linux kernel you are running? Please note that Beaglebone, capes and Angstrom Linux are not supported on this forum, but by the community at www.beagleboard.org.

Hi Biser

Though am using Beaglebone , but it uses AM335x(TI). And am running 3.2 Arago on it available at ti-sdk-am335x-evm. And am able to build and load Graphics_SDK_4_08_00_01 on it .

And as i mentioned generic applications are running fine. but why 3D is failing to run.

can you please give me some suggestion here .

Thanks!

Hi Prabindh

Thanks for ur reply.

Basically am using Imagination RC2_1.9 user mode ddk with TI Graphics_SDK_4_08_00_01, and am succeeded in running 2D unittests after debugging. But failing in case of 3D. But i discovered libpvrPVR2D_FRONTWSEGL.so was not there in imagination ddk which is responsible for direct framebuffer writing. So replaced that with libpvrPVR2D_BLITWSEGL.so under /etc/powervr.ini and am able to run 3D but with less fps..about 56fps. Am feeling probably imagination user mode RC2_1.9 ddk is having the maximum capacity of 56fps. And 56fps even not a very bad frame count.

Is that am on right track ?

Thanks!
