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.
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:
