This chapter describes ways to fix problems you may encounter when you work with the reference image for the NXP iMX8QM-MEK. You should also see the release notes for this reference image to check for known issues or limitations.

In general, you can look for errors in the system logs (slogs). For example, you can run the following command to check for errors with the Sensor service:
