“When I first got the HyperPixel 2.1 Round it would power up but not display anything. With the help of Pimoroni support I got it working by installing the older SD card image bullseye 2022-09-06 and after that it works perfectly. The display is great and works well even with the regular gui, though of course it being round you can only see the middle of the screen area! The device and Pimoroni are highly recommended.”
“Lovely display, looks beautiful, and great support from Pimoroni. (Got it working using the archived Raspbian 2022-09-06-raspios-bullseye for anyone having difficulty)”
“If you are comfortable with kernel logs, udev rules, and a little swearing, the HyperPixel rewards the effort. If you wanted plug-and-play, this will make you furious.
Pros: Stunning display; touch can be reliable; compact and high-quality hardware.
Cons: Setup feels like ritual sacrifice; drivers and overlays collide; examples sometimes break and expect you to be a sysadmin.
Verdict: Great hardware. Software experience earns a stern talking-to”
“The display looks really good. However, there needs to be updated guidence/instructions to get this to work. The built in hyperpixel kernel drivers do not work in the latest Linux Kernel for the Pi. I had to use an older Bookworm image with a kernel version of 6.6 to get the drivers to work (Nov 2024). I also have an issue where if I perform a soft reboot the display will not work again until I unload the DPI drivers and then reload them. I created a shell script to do this for reboots, but I do not like this band-aid solution.
I would also suggest that updates be made to support the Pi 5 GPIO structure so that touch can be enabled.”
“The Pimoroni HyperPixel is absolutely beautiful! I got it working on Raspbian Bookworm using the archived image raspios_arm64-2024-11-19 from here:
https://downloads.raspberrypi.com/raspios_arm64/images/
To make it work, I added the line dtoverlay=vc4-kms-dpi-hyperpixel2r to /boot/firmware/config.txt and ran the command:
sudo raspi-config nonint do_i2c 1
Important: Do not run sudo apt upgrade, or it may stop working.”
