Hi, 

 

I am looking for a solution to have the JustBoom and HifiBerry Audio Hat with dtoverlays working like in the TinkerOS 2.0.8 Image from ASUS.

Does someone known and has a procedure how to compile those and integrate in the Image or Compile a new kernel with its integration or a way to get those two hat's working?

 

Many Thanks for your help

I can take a look at this, my RPi keeps destroying its SD card and ruining my Volumio setup, so my hifiberry DAC Pro needs a new home.  I keep trying to channel the "millions sold" they use as a defense of their design choices, but it just doesn't seem to matter...

Hi Tony, 

 

Thanks a lot for your help

 

Here are the files we should integrate into the actual 4.19.x kernel and 5.0.x for the Tinkerboard, I have tested them and they are working!

 

https://github.com/TinkerBoard/debian_kernel/tree/develop/sound/soc/rockchip

 

and the coresponding dts files

 

https://github.com/TinkerBoard/debian_kernel/tree/develop/arch/arm/boot/dts/overlays

 

I think those are almost all very useful to integrate all of them to give advantages in hat Compatibility. 

 

Have a nice Day

Sorry for the silence.  Starting with the Asus overlay https://github.com/TinkerBoard/debian_kernel/blob/develop/arch/arm/boot/dts/overlays/justboom-dac-overlay.dts

 

The Overrides exploded the patching process 100% of the time, I didn't get that debugged yet.  perhaps @martinayotte has something interesting on that.  The power supplies I commented out because they're named/structured differently in the 4.14 + kernels and it seems to fallback to a dummy anyway.

 

The interesting issue I haven't quite gotten is why the sound node isn't obeying a "disabled" patch, the normal soundcards are still loading as though nothing has been changed (Yes, I am watching the boot terminal to make sure the overlay applied).

 

I was finishing the launch of a crowdsourcing for a project of mine, and some unexpected family health issues have been in the way, I think there might be a higher intervention against my working.

 

Below is the WIP overlay, no override and I also added a "sound-ext-card { }" section to the device tree to target these hats at.  My DAC is a Just Boom DAC Zero, but it should be extremely similar (might be pcm5122 instead of 5121)

/dts-v1/;
/plugin/;

/ {
	compatible = "rockchip,rk3288";

	fragment@0 {
		target-path = "/sound";
		__overlay__ {
			status = "disabled";
		};
	};

	fragment@1 {
		target = <&i2c1>;
		__overlay__ {

			dac: pcm5121@4d {
				compatible = "ti,pcm5121";
				reg = <0x4d>;
/*
				AVDD-supply = <&vcc_io>;
				DVDD-supply = <&vvcc_io>;
				CPVDD-supply = <&vcc_io>;
*/
				status = "okay";
			};
		};
	};

	fragment@2 {
		target-path = "/sound-ext-card";
		__overlay__ {
			compatible = "justboom,justboom-dac";
			i2s-controller = <&i2s>;
			status = "okay";
		};
	};

	fragment@3 {
		target = <&hdmi>;
		__overlay__ {
			hdmi-i2s-audio-disable;
		};
	};

};

 

Hi all, 

 

I still stuck on compiling and loading dts files to get the Sound Hats like HifiBerry working

 

This following had @martinayotte sent me some time ago:

 

mkdir: cannot create directory '/sys/kernel/config/device-tree': Operation not permitted because on my system the path stops at

This mean that Tinkerboard S patches don't have equivalent of the following patches :

 

Answer:

 

https://github.com/armbian/build/blob/master/patch/kernel/sunxi-dev/general-add-configfs-overlay.patch

https://github.com/armbian/build/blob/master/patch/kernel/sunxi-dev/general-add-overlay-compilation-support.patch

 

Maybe simple copies of those into proper patch folder can make it work, maybe additional tweaks are required ...

 

 

Does anyone can give me a solution for the latest dev kernel?

I would also pay for a solution in the dev / default installation image! Contact me first to discus the Price and the delivery date / solution

 

Many thanks to all con

Did you gave it a try ?

I don't have any Thinkerboard, but it should be pretty straight forward ...

I have a Tinker but no internet, so I'm having a hard time.  :-/

Hello,

Yes I have tried it but on my RockPi 4 which was not working. and on my Thinker Board S

I am really at the beginning of development. But will try again this weekend

 

Thanks

Hi all, 

 

I have tried to do the Following:

 

apt-get -y -qq install git git clone --depth 1 https://github.com/armbian/build cd build

Then put the following two Files

 

https://github.com/armbian/build/blob/master/patch/kernel/sunxi-dev/general-add-configfs-overlay.patch

https://github.com/armbian/build/blob/master/patch/kernel/sunxi-dev/general-add-overlay-compilation-support.patch

 

In the folder

 

kernel patch folder but after compiling normal or next with the following command

 

./compile.sh

 

I con not see any Files in the /boot/dtb nor in /boot/dtb/overlays

 

I have found now Kernel Source Files from HifiBerry Direct

 

https://github.com/hifiberry

 

I hope someone can take care of this because i'm not a programmer but just a normal User.

 

Hope someone can help me
