Hyperpixel 4.0 Screen not working - service fails

Hi All,

First post, just received my Hyperpixel screen.

I am trying to attach this to a RPi4, however after sudo apt-get upgrading and updating from a fresh install, I run the install.sh script for the Hyperpixel, reboot and I don’t get anything.

This is the output from install.sh:

pi@raspberrypi:~/hyperpixel4 $ sudo ./install.sh Job for hyperpixel4-init.service failed because the control process exited with error code. See "systemctl status hyperpixel4-init.service" and "journalctl -xe" for details. Installed: /usr/bin/hyperpixel4-init Installed: /etc/systemd/system/hyperpixel4-init.service Installed: /boot/overlays/hyperpixel4.dtbo Skipped: dtoverlay=hyperpixel4 already exists in /boot/config.txt Skipped: overscan_left=0 already exists in /boot/config.txt Skipped: overscan_right=0 already exists in /boot/config.txt Skipped: overscan_top=0 already exists in /boot/config.txt Skipped: overscan_bottom=0 already exists in /boot/config.txt Skipped: framebuffer_width=800 already exists in /boot/config.txt Skipped: framebuffer_height=480 already exists in /boot/config.txt Skipped: enable_dpi_lcd=1 already exists in /boot/config.txt Skipped: display_default_lcd=1 already exists in /boot/config.txt Skipped: dpi_group=2 already exists in /boot/config.txt Skipped: dpi_mode=87 already exists in /boot/config.txt Skipped: dpi_output_format=0x7f216 already exists in /boot/config.txt Skipped: display_rotate=3 already exists in /boot/config.txt Skipped: hdmi_timings=480 0 10 16 59 800 0 15 113 15 0 0 0 60 0 32000000 6 already exists in /boot/config.txt

Any ideas? Seems like the service isn’t starting. Reminder, this is a fresh install, upgraded, running Raspbian Buster Lite with no desktop as of yet. Will be using Openbox if I can get this working! I just want to display a picture or something at the moment, start simple.

Please help!

EDIT:
I have instead run the setup script here: https://github.com/pimoroni/hyperpixel/tree/pi4

Still nothing displaying on the screen, but I also have no desktop so…

EDIT #2:
Just tried sudo fbi -T 1 -a loadscreen2.png. Blank screen. Any ideas? I am SSHing in. Reason why I am using Lite is because I want the OS to be as lightweight as possible - I know that I could get this to worth with normal Raspbian.
