using IMU sensors
The documentation implies that there is a built-in 6-axis IMU (BMI160) included in the extension board. I tried running the example sensing -> application -> step counter, but I keep getting the error failed to read from I2c. I also tried connecting an MPU6050 sensor and addressing it as 0x68, but I still get the same error. So the question is, am I missing some connections in order to use the BMI160 (if it is actually built-in) or is my Spresense board faulty?

@tamer_ae what additional board do you have? The small sensor board that plugs into the top of the Spresense main board like this one has the IMU sensor. The larger expansion board that has the UNO form factor (that the Spresense plus on top of) does not have an IMU sensor.
@dshilov-1-1 Thank you for your reply.
I only have the extension board. I thought that was a different sensing add-on as the accelerometer included in the EVK-701 is not BMI160.
I do have another IMU which I tried to use but I keep getting the failed to connect to I2c error. is there a way to check if the hardware is fine or not?
