Trouble setting up my new Hyperpixel 2.1 round

Support

I have been trying to get my Hyperpixel round screen to display anything but with no luck. I am using a brand new Pi Zero 2W with 32bit Bookworm. What is the best way to get a current step by step installation walkthrough? I tried getting ChatGPT to guide me but I think it led me off a tall cliff :D

Some sites say it is only compatible with older versions of the OS…ChatGPT tried to get me to install the libraries for the Hyperpixel 4 because the GitHub links for the 2.1 GPIO setup were broken…. It has been rough, and I’d appreciate any help I can get.

Ideally just the basic setup to get anything to display on the screen would be a great start…

It might be worth trying flashing a slightly older version of Bookworm - recent kernel versions seem to have introduced some incompatibilities with older Pis.

I had success with this one:

https://downloads.raspberrypi.org/raspios_arm64/images/raspios_arm64-2024-11-19/2024-11-19-raspios-bookworm-arm64.img.xz

and otherwise following the instructions on the shop page - adding dtoverlay=vc4-kms-dpi-hyperpixel2r to /boot/firmware/config.txt and disabling I2C.

That worked! it was the OS version that wasn’t letting the screen light up.
