Board: Raspberry Pi 3+ model 1.2
DAC: Beocreate 1.0.2
I flashed an SD card with the latest HifiBerry OS and connected everything: Rainbow screen
Booting Pi without DAC: Rainbow
Tried the Disable EEPROM Trick (https://www.hifiberry.com/docs/archive/rainbow-screen-disable-eeprom-usage/): Rainbow
Flashed the same SD card with an earlier version of HifiBerry OS: Rainbow
Tried another SD card: Rainbow
The only way I can get the Pi to boot is to use a regular Raspberry Debian
