nrf5340 and BMI270 issue

Hello, I'm having the same issue as in this thread but the proposed solutions doesn't work for me. This is the output from the terminal:

*** Booting Zephyr OS build v2.7.99-ncs1-1 ***
Could not get BMI270 device

I tried using SPI earlier but that didn't work either.

I am on mac and using vscode to build and flash.

  • Hi,

     

    Which pins are you using for I2C (or SPI) ? How does your overlay file look like?

     

    Kind regards,

    Håkon

  • Hello. I used the bmi 270 example provided by zephyr https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/sensor/bmi270

    With overlay file modified as such to use pins 25 and 26 for scl/sda:

    I attached them to these pins on the breakout board:

    Zephyr.dts looks like the following:

  • Hi,

     

    The overlay looks ok. Have you scoped SCL and SDA pins to see if there's any activity?

    Both pins shall be active low, ie. idling at VDD.

     

    Kind regards,

    Håkon
