I am using the wayland imx-image-full image with chromium added
If I use the mipi hdmi dongle things work swimmingly and can verify chromium works

 

I tried: 
U-Boot > setenv fdt_file fsl-imx8mq-evk-dcss-rm67191.dtb
U-Boot > run bootcmd

however it fails on boot and manually starting weston does not succeed:
