I have just bought HiFiBerry Digi+ for my Raspberry 2 with Rasbian.
Unfortunately when HiFiBerry is installed I my raspberry doesn’t boot. It stops at the beginning so I can see only the rainbow screen.
Without the hat Raspberry boots and runs properly.
I found similar case “Rasp Pi2 OpenElec 6.0.0 DAC+ rainbow screen” and followed the advice
I was trying several different Jessie images, power supplies and sd cards. I also used HiFiBerry installer but the result was the same.
The “raspbian-preconfigured.img” from this web site which starts properly and works but after updating ( apt-get upgrade) my raspberry didn’t boot as the others images.
The test tone generator https://www.hifiberry.com/guides/sd-card-images/ also boots and works.
I’m confused and I don’t know what else I can do.
