Hi,

Are you using the Zephyr or nrfx SPI drivers? Can you share your full project?

Best regards,
Marte

what heppens is i am tying to communicate with my sensor. i am trying to read the WHO_AM_I register but I don't get a reasonable result (it returns 0)
after debugging I saw that the driver expects the pins numbers to be inside this structure:

it is inside the bus that is inside the spec
bus->config->def_config
as you see, I had to cast it to the structure I saw it is casted to deeper inside the callstack.
you can see that the sck_pin, mosi_pin and miso_pin are all 0.
this is the overlay:

Hi,

Can you share how you are using your spi_dt_spec and explain what you mean by it not getting the right pins?
Please also share your devicetree file where you define kx122_spi.

Best regards,
Marte
