Qt applications are not proprely working (huge delay) on i.MX6UL

[Poornesh7]

We are using i.MX6UL SoC for our project . We have successfully integrated LCD to our custom carrier board and we have successfully built yocto images (Yocto : Zeus ,DISTRO=fsl-imx-wayland )for the target SoC .

But when I try to run Qt application it is very slow and I could not able to do any functionalities .

So requesting to kindly suggest me whether I need to add any Qt related packages or need to build again for any other DISTRO .

Thanks in advance

You should use fsl-imx-fb to build, i.MX6UL only supports Frame Buffer graphics.

Thanks for your valuable response !

It's gald to inform you that our Qt application is working as expected without any delay after building with "fsl-imx-fb" as mentioned.

But I have other query , we have developed our Qt application with some animations (gifs) . But here these animations are not running .

Please kindly suggest me whether I need to add any extra packages for animations (gifs) to run .
