How can I successfully drive an SPI display based on this tutorial? I am using the latest Raspberry Pi 5B+ Bookworm image.

[jieweizero]

The Raspberry Pi 5B has been released. I followed the original tutorial to set up the Bookworm image on a Raspberry Pi version below 5B, and it successfully displayed on the SPI secondary screen. However, when I tried the exact same configuration on the Raspberry Pi 5B, it failed (Note: The SPI secondary screen has backlight and seems to initialize, but it doesn't display any content on the screen. When I enter "pi@raspberrypi:~ $ fbcp" in the terminal, it shows "* failed to open vchiq instance"). What should I do? Help!
