Does this work with RPi 5?

[JacobHJensen]

Followed the documentation from https://github.com/pimoroni/hyperpixel4/tree/pi4 and https://github.com/pimoroni/hyperpixel4/issues/177 but to no avail.

I've edited the config.txt aswell, but no dice.

Same question here about the RPi 5 - I see the splash screen when I reboot, it fades out, pops up again, then disappears. There is a small blinking cursor in the corner.

dmesg reports: (grepping for error lines only)

No errors in the boot log.

I've reinstalled the OS (Linux raspberrypi 6.6.31+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.6.31-1+rpt1 (2024-05-29) aarch64 GNU/Linux) but the problem remains. I tried this installation

git clone https://github.com/pimoroni/hyperpixel4 -b pi4 but it fails even if I update the python gpio library using sudo apt install python3-rpi-lgpio

I can confirm that at least Raspberry Pi OS Bookworm (Lite) works on a Raspberry Pi 5. I can see a terminal.

[MacEdgar1]

The screen does work with the Raspberry PI 5. Using min with Klipper. Was having issues getting the touchscreen to be correct.

https://forums.pimoroni.com/t/hyperpixel4-screen-rotation-touchscreen-fix-how/14778/9

The Raspberry Pi config.txt is in /boot/firmware/...

This entry allowed me to rotate the screen so it's in landscape with the power cable on top.

dtoverlay=vc4-kms-dpi-hyperpixel4,rotate=90,touchscreen-swapped-x-y,touchscreen-inverted-y

[JacobHJensen]

Hi MacEdgar1 - thank you very much for your reply!

Your dtoverlay-line combined with raspi-config > advanced > Wayland > select X11 made the screen show an actual image this time.

However, the "rotate" part did not seem to work, but with an image I could go to Preferences > Screen Configuration > Layout > Screens > DPI-1 > Orientation > Right (to get the power-cord on top).

Thank you very much for your comment! :-)
