I built a testing kernel, not only includes the fix for USB host, but
also includes all new patches from
https://github.com/raspberrypi/linux.git rpi-5.3.y branch (about 107
patches).
I tested both arm64 and armhf kernels on Pi4 without HDMI monitor,
everything works well.
Could anybody help
So far, what I got from investigation is:
After setting vc4-fkms-v3d, the fb driver's sequence is bootloader ->
simplefb -> drm_vc4 fb
Without vc4-fkms-v3d, the sequence is bootloader -> simplefb ->
bcm2708_fb (the screen will flicker when bcm2708_fb takeover the
display)
I will continue
I mean the simplefb driver in the kernel in the #3, I didn't know there
is a simplefb driver in the uboot too.
So it looks like: uboot.simplefb ---> kernel.simplefb works fine
uboot.simplefb ---> kernel.simplefb > drm_vc4_fb works
fine (but RPI3A+ crash)
I reproduced this bug on my rpi4 board.
