I have addeddtoverlay=vc4-kms-dpi-hyperpixel4in the /boot/config.txt file as shown below and rebooted the Rpi 5 but the display is blank.

Same here with a Square.

By the way, it works with Ubuntu 23.10 so I can confirm the display is fully functional. But, of course, I would like to use it with the RPi OS Bookworm (64bit).

It works on a Raspberry Pi 5 by following instructions from this comment: #177 (comment)
