Hi,

Do you know what may cause dmesg showing full wall of this error:

This error occurs every time I run java, but also in some other programs.

 

board: pine64 rockpro64

os: armbian ubuntu focal based image, but i deleted graphical environement and some other programs like libreoffice

It also looks like I'm getting SIGSEGV during apt update now:

So I just found out that my NanoPI M4V2 is doing this too ...

 

Armbian monitor debug for the interested: http://ix.io/2P0s

[   21.144731] rockchip-i2s ff8a0000.i2s: ASoC: error at snd_soc_dai_set_s

 

Maybe something up with the RK3399 device tree?

So, until I get more information on what's going on, I disabled both I2S devices on my M4V2 to shut them up.

 

There are some DTB differences between rockpi64 and M4V2, but they're pretty close. Perhaps this will work for you too, to at least stop the log spam. Save the below as "rk3399-disable-i2s.dts".

  

/dts-v1/;
/plugin/;

/ {
	compatible = "rk3399";

	fragment@0 {
		target = <&i2s1>;
		__overlay__ {
			status = "disabled";
		};
	};

	fragment@1 {
		target = <&i2s2>;
		__overlay__ {
			status = "disabled";
		};
	};
};

 

Then add as a user overlay on your system ...

  

tparys@m4v2:~$ sudo armbian-add-overlay rk3399-disable-i2s.dts 
Compiling the overlay
Copying the compiled overlay file to /boot/overlay-user/
Reboot is required to apply the changes
