Hardware:
- Raspberry PI 3A+
- Pimoroni HyperPixel Square Touch (purchased in 2020)
OS:
- Raspberry PI OS (64-bit) Bookworm.
Issue:
- Screen shows colored bars and flashes very rapidly.
Steps:
- I refreshed the SIM with the latest OS using Imager.
- Then I followed the instructions to update /boot/firmware/config.txt with
dtoverlay=vc4-kms-dpi-hyperpixel4. - I ran
sudo raspi-config nonint do_i2c 1)and confirmed using rasp-config that both i2c and spi are both disabled.
Is there anything else that I should be doing? Could it be a compatibility issue? Or maybe the screen has gone bad? Any thoughts are appreciated.
