4 years ago Hey :)
This is normal; there's no video output - the kernel runs 'headless' unless it's compiled in debug mode. If you connect a MIDI device and play some notes, you should see the LED blink when a message is received.
I should probably clarify this in the docs.

I'm getting a rainbow screen on boot with the newest release. Using a Raspberry pi 3 Model B. I believe I've ruled out the hardware because:
this is occurring on two different Sandisk SD cards (formatted with the official SD Card Utility)
I'm able to boot/run Raspberry Pi OS (Minimal image based on Debian Buster) with no issue. I also ran the 'full-upgrade' while this was booted
I can query the i2s DAC once in Pi OS (returns 4d)
The only thing I haven't done yet is hook up my Roland UM-One via USB - would this prevent the kernel from booting?
Any help would be appreciated, this looks like a great project!
