OpenGL ES support on i.MX8m mini EVK

Hello all,

 

I'm trying to use the NXP Evaluation Kit for i.MX8 M Mini.

i.MX 8M Mini Evaluation Kit | NXP 

 

But I've got an issue using graphic acceleration.

Indeed, when I try the Qt5_CinematicExperience, the FPS displayed are pretty low (about 18fps).

 

Is there anything to enable to have better performance?

 

I've build the sdcard image with the following steps (based on i.MX_Yocto_Project_User's_Guide.pdf) :

 

repo init -u https://source.codeaurora.org/external/imx/imx-manifest  -b imx-linux-sumo -m imx-4.14.98-2.0.0_ga.xml

repo sync

MACHINE=imx8mmlpddr4evk DISTRO=fsl-imx-wayland source fsl-setup-release.sh  -b bld-imx8mmlpddr4evk-way

bitbake fsl-image-qt5-validation-imx

Next on the board :

root@imx8mmlpddr4evk:~# Qt5_CinematicExperience -platform wayland-egl

I'm using an HDMI screen to display the application.

 

 

On another aspect, is there any way to use direct framebuffer like we can do on i.MX6 board?

Having the Wayland desktop displayed does not seem adequate for industrial purpose.
