I’m resting my Pi with the Hyperpixel 4.0 on it’s side so that the PSU and HDMI ports face upwards. The original installation instructions end up with the display upside down, so to fix this I changed display_rotate=3 in /boot/config.txt to display_rotate=1. Unfortunately the touchscreen sensor has…

This is something I forgot to add into the HyperPixel4 dtoverlay- the only way to rotate the touchscreen I’m aware of is to do it at the driver level. I’ve fixed the software to do this: Replace your /boot/overlays/hyperpixel4.dtbo with https://github.com/pimoroni/hyperpixel4/blob/master/dist/hype…

Try lcd_rotate instead, and let me know if that works.

Thanks! I’ll try that this evening. :)

Unfortunately the touchscreen isn’t working at all now. I initially obtained the .dtbo file with wget and replaced it with the one in boot as suggested, along with the config changes, but upon a reboot the screen no longer worked. I then decided to rebuild the SD card with a clean 2018-06-27-raspbia…

Drat! I tested it locally first and the software change wouldn’t affect the touchscreen hardware. Worth checking the output of “dmesg” to see if it has any entries for “goodix” and any clues as to what might be going wrong. Keep me posted!

Rebuilt using a fresh image but this time tried git clone and touchscreen still didn’t work, so I changed back to the previous commit using git checkout -b new_branch d612075460eb8072e9ea8f526c8b11fc9a836da1, rebooted and now touchscreen works again. Went back to latest commit and touchscreen doesn…

What happens if you; grab the latest source from GitHub, go into the “src” directory and type “Make” to build your own dtbo file Copy that hyperpixel4.dtbo into /boot/overlays Reboot There’s nothing in the new overlay source that should cause the touchscreen to not work, but I wonder if I’ve some…

It looks like your suggestion works as someone else has had chance to do this already - Hyperpixel 4.0 - touch not working

Aha! Brilliant. Yeah it looks like I missed some crucial quirk of the compile process. I’ve reverted to the older .dtbo in GitHub now and updated the instructions for people who want to rotate. I believe building the dtbo should be part of the install process. This will hopefully all be academic wh…

My screen has rotated but the touch axis are still inverted. I’ve done the 2 steps you mention, updating the display_rotate=1 and dtoverlay=hyperpixel4:rotate and rebooted, but the touch axis are still inverted. I’ve also downloaded the latest .dtbo file from Github and installed that over the old…

The latest dtbo on GitHub has been reverted to the version that doesn’t break, so you’ll need to compile the dtbo from the dts source in the src folder and use that. See the steps above, it should be pretty straight forward. I need to update the installer to do the compilation step automagically!
