1.5.3 Troubleshooting Device Drivers Error
Driver functions will return a status code when they are called to perform
a certain task for the application. When a function returns a code that is
not zero, it means the function has failed to perform its designated func-
tion. To troubleshoot the Device Drivers error, you can pass the error
code to
DRV_GetErrorMessage function to return the error message. Or
you can refer to the Device Drivers Error Codes Appendix in the
Device Drivers Manual for a detailed listing of the Error Code, Error ID
and the Error Message.
