@tooz By the way, here is my dmesg with some errors.

Yes, I did reboot empty mean all printed addresses are "_"

Device is si5351chip I've just changed #intf:i2c6=off to intf:i2c6=on from the default, i do have 6-th here: ls /dev/i2c* but i get empty line from sudo i2cdetect -y 6

hi everyone I think I'm doing smth wrong with my tinker board 2 I've turned on all i2c overlays and connected i2c device to pins 3,5, double checked wires i2cdetect can't detect any device, prints empty bus, but device is connected What am I missing ?

ADC is pcm1804, but it doesn't matter, as basically all I need is master clock signal, taken from i2s. I can test master clock adding with a DAC pcm5102. That's what I'm doing. I'm using hifiberry-dac-overlay with changes above, and in addition to usual i2s I want to get master clock on one of the pins. As I think, it can be done with adding i2s-8ch-mclk to an overlay. The question is how ? pcm 5102 connected and it sounds OK, I'm probing additional pin with oscillograph, hoping to get master clock

@tooz, Any ideas, please ?

For a simple test, I'm adding usage of i2s_8ch_mclk to a hifiberry dac overlay. I want to see not just i2s signal, but also master clock on pin 37 (phys num). There no master clock, just i2s for now. What am I doing wrong? Any ideas, please, help! Overlay (Linux linaro-alip 4.4.194) : #include <dt-bindings/pinctrl/rockchip.h> #include <dt-bindings/gpio/gpio.h> #include <dt-bindings/clock/rk3399-cru.h> /dts-v1/; /plugin/; / { compatible = "rockchip,rk3399"; fragment@0 { target-path = "/spdif-sound"; __overlay__ { status = "disabled"; }; }; fragment@1 { target-path = "/hdmi-dp-sound"; __overlay__ { status = "disabled"; }; }; fragment@2 { target = <&i2s0>; __overlay__ { assigned-clocks = <&cru SCLK_I2SOUT_SRC>; assigned-clock-parents = <&cru SCLK_I2S0_8CH>; pinctrl-0 = <&i2s_8ch_mclk>, <&i2s0_8ch_bus>; status = "okay"; }; }; fragment@3 { target-path = "/"; __overlay__ { pcm5102a-codec { #sound-dai-cells = <0>; compatible = "ti,pcm5102a"; status = "okay"; }; }; }; fragment@4 { target = <&pinctrl>; __overlay__ { i2s0 { i2s_8ch_mclk: i2s-8ch-mclk { // GPIO4_A0 - RK3399 I2S_CLK rockchip,pins = <4 21 1 &pcfg_pull_none>; }; }; }; }; fragment@5 { target-path = "/sound-ext-card"; __overlay__ { compatible = "hifiberry,hifiberry-dac"; i2s-controller = <&i2s0>; status = "okay"; }; }; };

OK, I found: i2s_8ch_mclk: i2s-8ch-mclk { rockchip,pins = <4 0 RK_FUNC_1 &pcfg_pull_none>; }; Seems like I need this one to use in overlay to output mclk. How should I add it to a .dts file ?

Basically, I need to output clock signal to one of free gpio pins. It should be synced with other clocks of i2s. How can I do it ?

I got I2S working with a PCM5102 codec (DAC), but in the next board I would like to use a board which requires MCLK (256*fs). How to output MCLK as well additionally to BCLK/LRCLK?

and it's not adc, or I don't understand. I need a tested adc, please tell about if you have.

Thanks, but it's not hat 😞 It's usb device. Maybe other ?
