LSM6DS0, with zephyr shell command, receiving "z_arm_hard_fault"

[alvin7]

I'm working on an nrf52840 dk. I need to print the sensor data on the command line. I've added the sensor config to the prj.conf file as well as the sensor and sensor_shell. In the command line, when I type the command, "sensor get LSM6DS0" , I receive a "z_arm_hard_fault". What could be the issue? Anyone?

I'll attach the fault I got.

Hi,

Could I see your overlay file and your prj.conf file? Do you get a fault for other devices?

overlay

prj.conf

I tried using devices BME280, LSM6DS0 and MPU6050. BME280 has no problems running and gives me an output but the other two devices are giving me mentioned error.

CONFIG_MPU6050 is commented out in the prj.conf you posted, but I assume you mean that MPU6050 does not work if you include CONFIG_MPU6050=y ?

Does the LSM6DS0 command work if you remove the mpu6050 node from the overlay and remove CONFIG_MPU6050?

Remember that you need to run Project->Run CMake in SES after any changes to overlay or prj.conf

Yes, it does not work when I include it in the prj file. 

No, the LSM6DS0 does not. The BME280 works though. I always run cmake when I make changes to these files.

The label is always detected but then hard fault occurs while fetching data. Should the sensor device be always connected to the board for it work?

Also, in some scenarios, the device binding also doesn't work i.e it returns NULL. For the MPU6050, it just shows "Failed to find sensor MPU6050", when I try to run the sample with the sensor connected to the board. Can it be an address issue?
