Can you please provide an exact kernel version or better the dmesg after boot?

[TheAifam5]

The dmesg logs i can't provide right now. In the next week i will be able to send it. I can say that connected RPi2 screen is seen and binded to Compositor-1 with valid resolution.

Packages: linux-firmware-20161222 raspberrypi-firmware-20170127 linux-raspberrypi-4.4.45 raspberrypi-bootloader-20170131 raspberrypi-bootloader-x-20170131

If you need i can upload them.

Can you please update to rpi-4.9?

You'll need to attach the dmesg for us to do anything. And, yes, use 4.9.

FYI vc4-fkms-v3d fixed the issue out of the box.

The latest vc4-kms-v3d on 4.9 never showed up a thing on the display, only HDMI
