I bought a Raspberry Pi Zero W for the purpose of building this:
It has NOT gone well! First, I tried flashing the Balena image – boot was rarely successful and when it was, it didn’t connect to wifi.
Then I tried Raspberry Pi OS – two different versions. Both got stuck on the ‘rainbow screen of death’ after saying something about resizing a partition.
This morning, there isn’t any video output at all when booting with the Pi OS SD card, and the Balena one stays in a bootloop.
I tried 5 different USB power cables and there seem to be no differences. I’m using an apple iPad charger as the base, which is rated for 5V/2.1A.
Can anyone help at all? Apologies for the broad nature of the question but it is driving me crazy! What could I be doing wrong?
