Hi,

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

[77666.669616] rockchip-i2s ff890000.i2s: Fail to set mclk -22
[77666.669642] rockchip-i2s ff890000.i2s: ASoC: error at snd_soc_dai_set_sysclk on ff890000.i2s: -22

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:

Nice...

Edited December 9, 20205 yr by TRS-80
put moderate length output inside spoiler

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
