Attempting to use a Hyperpixel 4.0" on Raspbian Stretch Lite in a portrait configuration but touch is always orthogonal to the display. Normal instructions here https://github.com/pimoroni/hyperpixel4 work just fine for the base install. Using the normal dtbo or the src/make dtbo and modifying the config file doesn’t appear to correct the issue.
I’ve so far tried the following: going into /boot/config.txt and changing dtoverlay=hyperpixel4 to dtoverlay=hyperpixel4:rotate doesn’t correct touch to portrait. Changing display_rotate=3 to display_rotate=0 does, however, correctly set the image to portrait. Flipping the height and width makes it render across the full screen. With this done, everything is working except for touch.
Has anyone done this before? Are there generalized steps for modifying a dtoverlay to do this?
Any support would be very much appreciated, thank you.
