Did you get it working?

Hi there,

If you look at the BMI270 driver in Zephyr you'll see that it does a lot of stuff during the initialization routine. Some of this will return an error if not performed successfully.

You can try using breakpoints and the debugger and see if you can find out if the driver returns an error.

Another possible culprit can be that the correct I2C pins are not assigned. If you probe on SCLK, do you see any activity when you startup the device? If you look at the initialization routine in the driver, you'll see that it tries to write to the slave. Do you see the slave return an ACK?

regards
