Hyperpixel 4 rectangular, touch not working

[zero-IQ]

Installed a fresh install of rasbian 10 buster lite, then connected the hypepixel 4 rectangular touch and then installed the drivers online. Screen works but touch does not recognized, no touch response at all.

My Pi is model 3B Revision: a02082
Raspbian GNU/Linux 10 (buster). 5.10.103-v7+
Fresh OS setup

dmesg | grep Goodix give the following output:

On the latest version of Raspberry Pi OS it should suffice just to add dtoverlay=vc4-kms-dpi-hyperpixel4 to /boot/config.txt albeit we still need to figure out rotation.

[Gadgetoid]

To be more specific you should use the 64bit version of Raspberry Pi OS released on

Also the following script on 64bit Raspberry Pi OS released on 2022-04-04 (or later).

This can currently be found in Raspberry Pi Imager under "Raspberry Pi OS (Other)"

The following script should allow you to rotate the display, preserving correct touch input mapping:

I have the rectangular hyperixel4 touch, not the square.

[Gadgetoid]

Sorry meant to respond to the other issue. Working on Rectangular rotate script right now.

You should still be able to get the board running by adding dtoverlay=vc4-kms-dpi-hyperpixel4 to /boot/config.txt

[zero-IQ]

is this working with pi3B ?
and does it needs the full rasbian 64bit with desktop or i can use the lite 64bit version?

[Gadgetoid]

Sorry I also missed that you were using a Pi 3B. I don't actually know! It's been a long time since I touched a 3B. It should work, but it varies quite significantly from the 4 in how it's all handled.

What process did you use to get the drivers installed? And how are you testing touch input?

[zero-IQ]

I tried with the latest rasbian and installed the drivers online with the curl, that process failed, I had no image on the hyperpixel. Then tried the manual installation that failed too, no image. Then tried with legacy rasbian 10 "buster" and online installation of drivers, that gave me picture and no touch at first. I tested touch with klipperscreen, an application to control 3d printer.
Today tried another time with rasbian 10 full and online installation of drivers and I have picture but the touch does not rotate and the area of touch does not cover the whole screen area. Very mind bending.

[zero-IQ]

can this be the solution?

[Gadgetoid]

It might help, but things are supposed to be simpler and not more complicated 😬

The main problem with touch is that it's not explicitly scaled to the same size as the display. The touch panel might output values along X and Y from 0-65535 and the software - be that Xorg or a user application - must scale it to match. Normally there are some driver values to at least get somewhere with this.

The alternate driver is at least worth a try.

I'll see if I can find a Pi 3B and get anywhere with it.

[Gadgetoid]

Okay I just put my Pi 4 SD card into my Pi 3B and it works.

You should try the latest OS and the instructions here - #177

Everything else is outdated, broken and overcomplicated. Things like 3D printer control apps are going to get dragged kicking and screaming into this one true way.
