iMX8, iMX8PLUS-BB, Yocto, imx-image-multimedia

I am running the g2d_overlay_test, which is included in the image, direct write to /dev/fb0 and see results on screen connected via HDMI, however when I try the g2d_tests nothing happens and errors are returned invalid destination planes.

Does anyone have experience of running the g2d_overlay_test, what is should I expect to see and what am I doing wrong running the test ?

Thanks

Adding further debug, the frame buffer and screen information are populated, however the g2_blitEx appears to fail as the smem_start being 0 

g2d_blitEx: Invalid dst planes[0] address=0x0

Any ideas what I am missing to run this test ?

g2d_overlay_test using /dev/fb* is not compatible with i.MX8 Series.

Thank you for the reply,

Could you just confirm that these tests are not valid on the iMX8, as it was NXP support who advised to try the following. (For information what I am trying to achieve is overlaying dynamic graphics , such as gauges in on top of video in Realtime)

iMX8MPlus have following hardware accelerators available that might be relevant for your requirement:

  • GPU2D:
    • 2D graphics accelerator provides advanced composition capabilities.
    • Please refer to i.MX 8M Plus Applications Processor Reference Manual to understand its capability in more details.
    • Hardware can be used through G2D APIs (Please refer to Ch-2 in https://www.nxp.com/docs/en/user-guide/IMX_GRAPHICS_USERS_GUIDE.pdf dedicated for G2D APIs)
    • Sample tests for GPU2D:
      • Following tests are available to test GPU2D capabilities or performance (Yocto module: imx-g2d-samples):
        • g2d_multiblit_test
        • g2d_overlay_test
        • g2d_test

Framebuffer is not supported in i.MX8, so some code api is out of date.If you want to test g2d overlay function.

You should see this new branch:https://github.com/NXPmicro/g2d-samples/blob/imx_2.0/overlay_test/g2d_overlay.c

I have switched to the imx_2.0 branch, but get the same results when running g2d_overlay_test, I have also tried g2d_overlay_tile_test with similar result

I am running on the 8MPLUSLPD4-EVK using Yocto to build the multimedia image. the g2d-samples I build using the SDK from Yocto.
