Amanero Isolator/Reclocker GB

[dwjames]

James - would you make a recommendation? Been thinking about buying one for a while. TIA - Pat

The one I've just borrowed is a Veho Discovery and I'd recommend it. I have a cheaper Chinese one off ebay which cost half as much, but the software was crap and it broke on me after not much use...

I've had a frustrating time this evening chasing a couple of faults which were mainly u.fl soldering errors and the fact I'd bypassed the clock buffer, but these ndk chips definitely need it in place..... but I have a 45mhz clock mounted on my s03 in the x1 position and it's asynchronously reclocking well now.

I'm having trouble getting the BBB to do what I want though... It seems that regardless of what I do in the config file, it's playing double speed, so even though I have it set for clock option 0 it's still seeing an mck and just using that....

Could someone who has synchronous clocking working with 45/49 oscillators post up the contents of their uEnv.txt file and note which position they have which oscillator please?

Thanks,
James

Hi James, It sound like the clock divider on the S03 is not doing it's thing. Do you have the /2 resistor (would have to look up the nr.) in place?

This is how I've got it setup at the moment:

X1: 45.1584Mhz, X2: 49.152Mhz

initrd_file=initrd.img

##Enable systemd

##Disable usage of external Botic clocks

It's fair to say that it definitely isn't

An externally hosted image should be here but it was not working when we last tested it.

I'm not fitting a divider, but setting the frequency in the Botic uEnv.txt file so the division is done in the software.
I have this working with 44khz now and I'll add the second clock shortly.
The info I was missing is that the snd_soc_botic.clk_44k1 value in the file must be placed on the same line as the clock selection value.

I'll post up some info on what I've done when I have it sorted.

OMG..., it's gone!

 

[dwjames]

OMG..., it's gone!

Well, not fitted in the first place, but yes, it appears it's not needed at all if you're using the Botic driver for bbb as you just set the frequency in there and let the software handle it all.
I got it all working earlier today, but had guests here so only heard enough to confirm it works and nothing more.

Looking forward to hearing the results of a good few hours of work

The software side of things is easy enough once you've figured a few things out. I'll post a how 2 when I get a spare moment, but probably not for a day or so.

Hi James, I completed all the HW parts, I tested the S03 how much I can test without signals (various PS at the pins of the flip flop, XO and isolators)
I download and flashed the img miero file in the microsSD and I am actually ready to power up... I will wait your post before to understand how can go ahead and don't proceed blindly

Thanks for your help!

If you've got that far there's only really 1 simple step left I believe.
You can put the sd card back into your computer and look on the root of it for the file uEnv.txt
If you use windows or Mac you need a decent text editor, something like pspad (free)
Then just edit the line which says

optargs=coherent_pool=1M snd_soc_botic.ext_masterclk=0

And change the masterclk setting to be 3
Then save and you're ready to go I believe. It looks like your s03 is set up for 2x divider, so you don't need to change the frequency in the Botic driver.

Good luck!

Thanks James for your help.

I downloaded the pspad and modified the line as you said.

What about the remote control through ipad or android? My actual configuration with the Edel_NMR is really simple. The server is the NAS and the application BubbleUnPn recognize automatically both the server and the Edel as rendered. Will be the same for the BBB?

Sorry for the silly questions but I remember when I setup the rPi with Volumio was not easy at all for many reasons including my ignorance with Linux

Anyway tonight is too late for me to give a trial and tomorrow starting a new working week. I am also sure that some trouble shooting will need so better take it easy

Thanks again,
Enrico

With the current release of Miero's BBB software, no.
The core media server of Miero's Botic-v3 is Music Player Daemon. This requires MPD-compatible client controller applications - for Android something like MPDroid, for iOS something like MPoD/MPaD.

However, Miero said that in future releases he will include "GMediaRender" which you can use to turn the BBB into a UPnP renderer. Then you will be able to use a common controller application for all of your devices.

There's actually a third option, which is to add a plugin to MPD (upmpdcli) which turns MPD into a UPnP renderer application, itself. This seems an inefficient use of software to me, but apparently there are benefits. You can read about it here -
An UPnP Audio Media Renderer based on MPD
See the "What's the point?" section.
Miero mentioned that he is considering adding this plugin to future releases.

Thanks linuxfan for the detailed reply. I will give a look to the link trying to understand how can make the BBB work

Enrico, I currently have upmpdcli installed on my miero equipped BBB and it works very well at turning the BBB into a UPnP renderer; I also use BubbleUPnP as my controller app.

I have also used GMediaRenderer before and it also worked well but, at the time, was a little more fiddly to install. I'll happily switch to GMedia if it's included with miero's package in the future.

EDEL Combo

@Enrico,
I received your adapter board for Edel. Very nice design! Thank you for helping out
Once the S03 board is added the Combo will be ready for tests

An externally hosted image should be here but it was not working when we last tested it.

If this is the case do we then need RuneAudio or Volumio for BBB?

Ray, this is a good news, thanks!!
But I have another silly question... where you have the upmpdcli installed? I mean, I flashed the microSD with the miero img file and I modified as per your post above. How can I include the upmpdcli?

I am sorry to bother you guys with all this basic questions and I really appreciate your patience

You are welcome Acko... great you have it in the hands

The PSU in the picture is the one?

I am really curious to hear from you about the Edel and most insteresting the Edel with the S03...

I don't think so.

Enrico, here's the upmpdcli page;

An UPnP Audio Media Renderer based on MPD

All I did was download and install the RPi/Debian release on top of miero's software as per the instructions.

Here's the relevant page with the instructions.;

Upmpdcli downloads

It seemed very easy. I'm not a Linux expert by any means.

Thanks Ray... very helpful notes

I will go through the links as soon I back home and I will let you know.
