Using z160 GPU on a custom board

[oliviernasralla]

Hello,

anyone know (or have an idea) how to use the GPU of the imx51 on a board that does not come from freescale. My board come from another company and use his own BSP which doesn't provide the GPU driver and library.

I tried to copy all include, lib and bin files from the package "amd-gpu-bin-mx51-10.11.01" present in the freescale BSP source to my rootfs but I am not able to start any example. I get always the same error which say the application is not present, but it is...

Did someone already try something similar?

Thanks

Olivier

To be more precise, what I did is copy in /usr/lib/ of my rootfs:

• lib2dz160.so
• lib2dz430.so
• libcsi.a
• libEGL.so
• libGLESv1_CM.so
• libGLESv2.so
• libgsl.so
• libOpenVG.so
• libres.a
• libz160.so

and copy to /usr/include/ in my rootfs:

• EGL folder
  • egl.h
  • eglext.h
  • eglfslext.h
  • eglplatform.h
  • eglplatform_1.4.h
• GLES folder
  • egl.h
  • gl.h
  • glext.h
  • gl_extensions.h
  • glplatform.h
• GLES2 folder
  • gl2.h
  • gl2amdext.h
  • gl2ext.h
  • gl2platform.h
• KHR folder
  • khrplatform.h
• VG folder
  • ext.h
  • ftvg_utils.h
  • openvg.h
  • vgu.h
• z160.h

Is it enough to use the GPU or I need to load a driver on the board or something more?

thanks

Hi,

At this time i'm tryin to give an imx53 board a performance-boost by enabling hardware-acceleration for X11.

I've been trying to build and include hardware support for "Driver for Freescale IMX processors: i.MX5x Z160" into the X11 ( buildroot 2016-11) . Running ( building for) latest LINUX (long-term) kernel 4.4.43.

I've been able to compile and run the imx_X11 driver ... so far .. but it bails out ... with

(EE) imx(0): Unable to access Z160 GPU

Any clue ? 

I'm kind of stuck now... anyone out .. that can give me a hint ? 

Best Regards

Noel

Please check the i.MX51 part number on your board. There is no GPU in i.MX512 and i.MX513.

[oliviernasralla]

Thanks for answer.

I have the i.mx515, which have the GPU.

Actually I stay at the same place with my problem, have you some idea about the way I should add the GPU support on my board?
