Installing X-server or wayland on t1042

Installing X-server or wayland on t1042

Hello,


What is the procedure to install X-server or Wayland on T1042D4RDB-64B. I
see IMX BSP's are having these. Can we use similar recipes for
T1042D4RDB-64B. I am trying to have a video output from External GPU (
Connected via PCIe ).



And also what is the procedure to active video output from U-boot for
external GPU's ?



Thanks.

Yusuf,

   If you google 'i.MX_Yocto_Project_User's_Guide', it documents how to 
build Yocto for wayland on i.MX, with something like:

     DISTRO=fsl-imx-wayland MACHINE=wandboard source 
fsl-setup-release.sh -b build-wayland

     bitbake fsl-image-machine-test

You would need to port recipes to the build for your target. But, beware 
of drivers that are i.MX specific since they use features like the IPU 
and digital display interfaces on the i.MX6/8. If your external GPU is 
perhaps, Nvidia, you will need their recipes, if available.

The kernel boot command line options for video output are also very i.MX 
specific.

Regards, Clay

Thanks for the answer. I'll try it.

My external GPU is amd product and there is a driver in kernel 4.19
gpu/drm/amdgpu. I hope it probes X-server or Wayland itself.

Hmm it seems this is going to be another challenge if I setup X on my board
successfully.


There is another question I want to ask. Can I also setup something like
Gnome or lightdm. I saw some Gnome recipes in yocto source ?
