Cronus - It's about time.

[grael]

Do you have the exact reference of your audio gd hdmi/i2s module?
There are two of them, one i2s=>hdmi (which should work) and one receiver hdmi=>i2s (which won't work in your application)

And don't forget to connect GND

 

[GhostMM]

Yes i use the output version, i also connect the ground wire. I also check the voltage, my cronus get 5 v and my hdmi i2s have it's 3v3.

Also in my case, what should i use fort the clock ? My jumper is on 1:2.

I hope this is not a problem of compatibility with my dac

 

[grael]

Resistors installed on the cronus for the 3 channels you use?

Is your dac an audio gd too?

 

[GhostMM]

I install all the resistor. My i solder everything exept one led that is miss on my kit.

My dac is a musicaltech rd 40, it's hdmi i2s out is suppose to be compatible with psaudio spec, i asked directly them directly.

 

[grael]

I fear there can be a few differences between full psaudio specs and what audiogd use...
(Power or not, signal flags, etc.)
Hard to tell without full pin assignment scheme from musicaltech.

 

[GhostMM]

I think the problem come from the software side.

I will make a photo of my installation. I got strange things, i cannot access to mpd web interface with ip_adress:8080, it say "connection refuse" and i don't arrive to connect mpd with my mpd client (cantata), but i get a ssh root access to botic distribution, i tried to restart mpd but nothing change.

 

[grael]

If it's software related, I can't help, sorry...
You may ask Miero on those topics:

I post a photo of my installation, do you see somthing wrong ?

 

[grael]

I don't see any obvious mistakes here, but I don't know much about BBB-Hermes.
You need help from better informed persons, sorry.
Good luck with it!

HELP part 2

Hello!
i need some help with the amanero/hermes/cronus/rhea.
i got mine one a few weeks ago. today the last missing crystall came. i put all components together, flashed the amanero in slave mode - set the configuration bits... and nothing... daphile and windows found the device, but no sound. i checked all multiplier jumper, resistors, cables, conf. bites - nothing.

i got 2 amanero boards - no board was running in the setup. then i try to use the hermes without cronus. in normal mode an in slave mode... no sound. any ideas?

regards
limbik 5

can i check the hermes an Cronus seperatly without an osci?

When i only use the hermes for a function test.... do i need an 3.3V power supply for the clean side? normally it should be possibe to connect the isolated output from the hermes to my dac...

can i do the same with the cronus? directly th the amanero an than into the dac? if it is possible i can find out whats not workling...

i was not sure about the i2s output from the cronus. can you pls give me the right pins for sdata, bckl, gnd and LRSKl? after reading over 400 postings... i still was not sure.
THX a lot!

Hello, I posted my question already in the Hermes Amanero Thread which was possibly wrong. Once again:

In the Hermes/Amanero-thread Russ posted that it would be able to connect an Amanero and a BBB to the Cronus and switch between them.

How would the connection to a BIIISE be then?

BIII - Cronus - OTTO II and then Hermes BBB and Hermes Amanero attached to the OTTO?

BR, jan

 

[miero]

Hermes boards were not designed for such use complex use case.

However theoretically it is possible:
- use OTTO to route 1, 3, 5, 15 pins of Cronus to two Hermeses
- do not connect 7, 9, 11, 13 pins
- route other pins to both Hermes-BBB and Hermes-Amanero

But no warranty. This could damage something and also it might not work too.

Maybe Russ could clarify this.

 

[jannek]

Hello,

I think BIII - OTTO - 2x Cronus would also be no option? But even if that would work, the setup gets too complicated and expensive.
What about the possibility of the BBB acting as a USB Sound card you once mentioned?

 

[lbamda]

Whether somebody made the working decision for simultaneous work of (Amanero USB) and (spdif to I2S) through Cronus at synchro-mode BIIISE?

As far as will work (Amanero) + (spdif to I2S) ->OTTO-II->Hermes->Cronus->BIIISE ?
And it is better for what board spdif->I2S to use?

 

[jannek]

Hi there. Just assembling my Cronus at the moment. I would like to know what R1-R7 are for. I have seen pictures of all resistors just parallel, but on Miero's site, they are installed different... what is right?

 

[grael]

It all depends on the dac after the cronus.
Are you using multichannel on a BBB?
Or only stereo with amanero?

And what is your dac?

 

[jannek]

I begin to understand. The DAC will be a B3SE (when becoming available again), source is a BBB, Stereo only.

 

[grael]

Then you just need to solder r7, r6 and r5, parallel, and you're done

 

[jannek]

Thank you very much.

 

[jannek]

How is the connection to the B3SE done? Is there some sort of stacking header or is it necessary to use uFL connectors?
For sure no screw terminals?!
