Starting from uboot everything seems ok.
Loading the kernel seems ok and also loading the rootfs.
However the screen does not turn.
Despite having acted on both the device tree and the cmdline kernel.
My suspicion is that drm doesn’t transfer rotation correctly to the framebuffer.
See below entire loading process:
