https://devzone.nordicsemi.com/f/nordic-q-a/87053/nrf5340-and-bmi270-issueHello, I&#39;m having the same issue as in this thread but the proposed solutions doesn&#39;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 thaten-USTelligent Community 13Fri, 22 Apr 2022 08:47:22 GMThttps://devzone.nordicsemi.com/thread/364401?ContentTypeID=1Fri, 22 Apr 2022 08:47:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:67b00db1-c8e7-436e-89de-0e8515f44d8adewasser<p>Hello, I have not. I did when I tried SPI and most of the time there was no activity, sometimes some but it seemed nonsensical.
