imx8m Yocto fsl-image-validation-imx vivante driver for X11

[maciejka_miercz]

Hello,

We have build Yocto for imx8m using a steps provided by the "i.MX Yocto project user guide" and after command xinit there isn't vivante drivers for the X11.

How to build vivatne drivers for X11?

Problem is that vivante drivers for i.mx8m are missing, they didn't exists in /usr/lib/xorg/modules/drivers/.

In Yocto there is recipe for xf86-video-imx-vivante but that driver is for the imx6 processor not imx8.

We bought imx8mqevk and we cannot test it in X11 enviroment. Our appliliance uses X11 to communicate with the user.

Hi,

I recommend reading the "i.MX Linux® Release Notes, Rev. L4.9.51_imx8mq-beta, 01/2018":

Page 5 / Features on i.MX 8MQuad:

No X11 backend supported in i.MX 8MQuad.
