solved HiFiBerry on Rock64 howto needed

Recommended Posts

(edited)

Hello Armbian community

 

My HiFiBerry DAC HAT works well on my Raspberry Pi 3B with RasPiOS.  However, I would like to put it on my Rock64 to use the higher Ethernet and USB speed it offers.

 

As far as I can tell, HiFiBerry DAC is in the mainline Linux kernel - it is mentioned in the source code, but I do not understand programming, so I cannot see if it is used.  Is the HiFiBerry DAC supported in Armbian's kernel?  If so, how can I activate and use it?  I put the HAT on the Rock64 and installed Armbian_20.05.2_Rock64_buster_current_5.4.43.img.xz , and it booted without problems, but I could not get sound out of the HiFiBerry DAC, and Alsamixer showed no controls for the sound hardware.

 

I also tried making a Virtualbox to compile the Armbian kernel, and I could get the build environment to work, but I did not find any clues to include support for the HiFiBerry DAC - yes, I am truly clueless when it comes to programming, but I can follow a step by step recipe.

 

Please give me a recipe for getting the HiFiBerry DAC to work on Rock64 with Armbian.

 

Best regards

Freddy

Armbian is a community driven open source project. Do you like to contribute your code?

Hey, this will not work..

 

Have you seen the data sheet of the Rock64?

 

There is no I2S on the Pi-2 Bus (pinheader) where you connected the HiFiBerry DAC from your RPi.

You can use jumper wire to connect it with P5 but you need a overlay to activate I2S.

Thank you MacBreaker, that clears up everything.

 

Yes, I have _looked_at_ the data sheet, but I am even more clueless about electronics than I am about programming, and I would not dare to come near a soldering iron.  :(

 

I will just keep things unchanged and see if I can use the Rock64 for something else.

 

Best regards

Freddy
