You should be using the kx122_spi instead of spi2. I also don't think you should name it SPI2_XX, from what I can see in the documentation and personal experience it's enough with just SPI_X.

I would expect some of the issue here is that you are trying to get the wrong spi instance, you are after the sensor and not the whole spi instance after all.

As it is a custom driver, how did you implement it?

Which version of NCS are you using? Node label is deprecated in newer versions

[quote user="shlomots"]define SPI2_CS_PIN DT_PHA_BY_IDX(SPI2_NODE, cs_gpios, 0, pin)[/quote]

Try with

SPI_CS_PIN DT_PHA_BY_INDEX(kx122_SPI, cs_gpios,0,pin)

Thamk you for your response!
1.yes
2.I know
3.I changed the frequency but it still doesn't work.
this is how I am trying to get the information in my code:

#define SPI2_NODE DT_NODELABEL(spi2)

#define SPI2_CS_GPIO_CTRL DT_PHANDLE_BY_IDX(SPI2_NODE, cs_gpios, 0)

#define SPI2_CS_PIN DT_PHA_BY_IDX(SPI2_NODE, cs_gpios, 0, pin)

#define PINCTRL_NODE DT_NODELABEL(pinctrl)

Thanks

I can't find the device binding in Zephyr, have you added it to your project as a custom driver?

Btw from what I see the kx122-1037 is not recommended for designs and scheduled for obsolesce.

Edit; I would also suggest running spi2 on 8Mhz ref configuration

Hi Shlomo

Could you upload your overlay and prj.conf?
