Hi,
i've build the xwayland distro for imx6qpsabresd board, based on yocto thud and
uboot 2019-04 and kernel 4.19.35.
I have a hdmi panel plugged.
On uboot i'm able to get 1920*1080*60 resolution.
on the bootargs i have:
console=ttymxc0,115200 video=mxcfb0:dev=hdmi,1920*1080M@60,bpp=32 root=/dev/mmcblk2p2 rootwait rw
but when kernel starts, the panel switch to 640*480. I'm not able to get 1920*1080 as default.
after, when changing in /sys/class/graphics/fb0/mode, the resolution change but the display is not correct.
the same distro/kernel/uboot/display on a imx6qpwandboard works well
Any idea is welcome !
Thanks in advance

Hi,
my mistake,
the problem was the command line,
we must not use * but x for the resolution
1920x1080
with this it works perfectly
