Generally, in the operation process of the vehicle-mounted device, a situation of abnormal write-in configuration parameters occurs, such as power failure or strong interference on the vehicle, and the area where the configuration parameters are written is an update area of the nonvolatile memory. Therefore, whether the abnormal writing condition exists can be judged by reading the updating area of the nonvolatile storage and checking the read configuration parameters.
The verification method can verify the mark information of the head position and the verification information at the tail of the area. And the check mode at the tail adopts a CRC check mode.
And the third reading module is used for reading the configuration parameters of the backup area of the nonvolatile memory and verifying the configuration parameters of the backup area. When the verification of the configuration parameters of the update area fails, which indicates that the written configuration parameters of the update area are abnormal, the configuration parameters of the update area need to be restored through the backup area. And checking the parameters of the backup area, and if the checking is successful, performing subsequent operation. The verification method can verify the mark information of the head position and the verification information at the tail of the area. And the check mode at the tail adopts a CRC check mode.
And the first writing module is used for updating and writing the configuration parameters of the backup area into the updating area if the configuration parameter verification of the updating area fails and the data verification of the backup area succeeds, so that the configuration parameters of the updating area are recovered to be normal.
