Simple DSD SRC for BeagleBone

[diyAchim]

There are simplified SBCs based on BeagleBone - AntMINER L3 and D3
They can be purchased for as little as 5-10$.
I recommend using these boards. There is nothing extra on these boards that can affect the sound.

Thank you for the advice - I did not find any offer for these boards. Could you please point one out?

I am not familiar with the legal aspects of mining in Russia. But I see that now this equipment is being actively sold.

pure firmware can be used also for direct dsd in place of the "old" firmware that went for hqplayerd ?

Thank you, Pavel!

Yes, you can use this firmware.

If Pavel has no objections, I am considering running a small quantity group buy for assembled boards.

I don’t mind. But before you run the group buy, listen for yourself.
Lately I've gotten tired of listening and searching for the perfect sound.
DSD'it was heard in Russia by only a few people. But they all responded positively.

Thanks Pavel. I have enough experience of your projects to trust your assessment; logistically it would be much simpler to get a batch of boards assembled so I'll dive straight in if there is any interest from others.

I don't think perfect sound exists!

Yes, you can use this firmware.

any modification required ?
can i leave my current uEnv configuration ?

It is highly likely that nothing needs to be changed.
All settings are in the "optargs =" line of the uEnv.txt file.

as expected,
just tried... works perfectly with direct DSD output.
i have change optargs to copy my previous settings and that's it.

nice interface prettier by a long shot

BeagleBone is a powerful platform. Everything is limited only by your ideas and fantasies.
I had no plans to make hardware indication. Everything can be displayed via the firmware web interface. I was recently helped with the webdesign of the "Pure" firmware. In the future, I will expand it.

What software package gives all these applications? Looks very nice.

Building Linux from scratch.
The Buildroot is the basis.

Thanks! Is there even a Tidal app?

I am constantly haunted by errors with the numbering of the Amanero connector.
For DSC 2.6.2 you have to make the following cable:

The "Pure" firmware is a collection of network endpoints for various audio protocols.
If you know a client-server application for Tidal, I'll try to add it to the firmware.

If you are using Windows on your main computer, then Tidal can be listened to through "Scream audio".
If MacOS - AirPlay.
Or via Android and BubbleUPnP.

Hi PPY,
I understand these boards are made to operate with a BeagleBone board, but can it be used as a stand-alone DSD converter module?

 

[ppy]

No, this design will not work without a BBB.

... can it be used as a stand-alone DSD converter module?

Not as is. Seems like an Arduino and a USB board (or other I2S source) should be able to make it work.

 

[ppy]

I can do Amanero+DSD'it. You won't even need an Arduino.
I don’t promise about the timing, but it will not take long.

 

[Markw4]

Oops! Looks like you are using 45/49MHz clocks. Those should work fine as external clock sources for I2SoverUSB, but not directly as external clocks for Amanero. Amanero could be made to work too, but its a bit more complicated to do it with those since the clocks would have to be run though a divider.
