Hi,

 

I wonder, why the Sparky kernel is not updated for some time, stopped at version 3.x when the kernels are now version 4.1x?

Hi,

 

I wonder, why the Sparky kernel is not updated for some time, stopped at version 3.x when the kernels are now version 4.1x?
 

native dsd included and other improvements

[antonellocaroli]

I read all the pages, I think that many of the problems encountered are due to the so old version of the kernel .... in the new kernels there are improvements a bit for everything even audio ... a kernel so old is unthinkable!!!

 

sorry for the multiple posts, but I did not understand how to edit a message

[antonellocaroli]

a patch is just a patch ...
the kernels are also updated for other reasons ... see latency and more ....It is a unique project
you can not get such an old kernel ...

I still have no problems with sparki ... I still have to get there .... but if I had been better informed before ... maybe ...

When using DietPi i think SPARKY kernel is "patched", especially ALSA native DSD playback support. 

What is your detailed setup and issues ?

 

[antonellocaroli]

3.x kernel dates back to 2011 .... in 7 years you know how many things change in this area?

Efforts to upgrade the kernel to mainline are already well underway but they depend of the CPU manufacturer not us. I know they are working on it.

 

 

I've never heard that cpu manufacturers release the kernel ... it's a software component that releases and updates the manufacturer of the product (see raspberry...It has the same architecture)

Sorry but you are wrong. Only when the CPU manufacturer gets involved and releases all registries and closed source info , then only upgrading the kernel its possible. They are working on it.

 

I doubt that I do not accept the skills to update it !!! if it were a souce problem there would not even exist a 3.x kernel (remember that the kernel is open)

Meanwhile there are other commercial options if you need the latest kernel in a USB reclockcer.

 

good advice

Good luck

I agree but do you think USBridge would sound better and / or more reliable with "new" kernel ? I'm not sure.

I don't think "that many of the problems encountered are due to the so old version of the kernel" ... 

certainly we do not have the counter-test ... or the possibility to choose;)

the fact remains that patching the kernel (especially so old) to face solve something but create problems from other parts

 Please keep it civil.

I think I was civil, I just expressed what I think ...

[antonellocaroli]

@allo.com

to the kernel sources found here https://github.com/sparkysbc/sparky_linux_images, have the various patches been applied or should they be applied later?

[antonellocaroli]

arrived, made only trial operation, dips ...
I think my Sparky has problems ...
the system starts ... but I have no signal on the screen, as if there were no cables connected.

the Lan does not seem to work properly, the lights near the connector turn off for a few seconds (even 3/5) and then start flashing again.
I also have problems with the ssh connection ... even here as if it lost the signal ...

ideas?

ps: for those few seconds I was able to listen to music ... the sound seemed good ... but it loses continuously ... even with mp3 radio

 And USB defaults as soon as you change/alter the Allo Web Gui the default is changed into USB 1.2 instead needed USB 2.0.

 

 

 

 

Can someone explain better how this configuration works?

why is not 2.0 default?

it should be the kernel that detects the type of ports

[antonellocaroli]

I would like to use gentoo on the sparky card.

I compiled the kernel and the compilation was successful.
also the installation of the modules is ok.

But I did not understand how the boot partition should be populated.

I have a zImage file in /arc/arm/boot/
and several files in /arc/arm/boo/dts/

can someone help me?

[antonellocaroli]

I have interruptions even doing upsampling at 384Mhz

I have these messages in the dmesg

I use dietpi, and I often interrupt even at 384Mhz

[antonellocaroli]

I've produced some sparky Gentoo-based images.
if anyone wants to try they are here
Unfortunately the description of the commands and some scripts are in Italian ... but I think they understand each other.

the software in use are:
Squeezelite-R2 (recommended for use on the PC "server" of LMS + C-3PO plug-in)

@rahul_kc   hello, a friend of mine has a problem with the dsd with Oppo BDP-105D. Is it possible to know how to apply kernel patches for dsd support? and add the id of the dac to the dsd support?
