I have already contacted Pimoroni Support via email. I have a new HyperPixel 4.0" w/Touchscreen, a new Raspberry Pi 4 Model B, and a new micro SD card, freshly rewritten for each os listed below.
I attempted to follow the instructions at: PSA: HyperPixel 4 (Square & Rectangular) on Raspberry Pi OS 64bit 2022-04-04 · Issue #177 · pimoroni/hyperpixel4 · GitHub and add: dtoverlay=vc4-kms-dpi-hyperpixel4 to the
/boot/config.txt file, but…
It failed when I used the latest Pi os: bookworm Dec 5 2023 64-bit.
It failed when I used the Legacy Pi os: bullseye Dec 5 2023 64-bit.
It fails when I use the Legacy Pi os: bullseye Dec 5 2023 32-bit.
Following is troubleshooting information I gleaned from: Raspberry Pi Buster Has Black Screen After installing · Issue #175 · pimoroni/hyperpixel4 · GitHub
