Solving system faults
Solving system faults
When the system detects faults (such as system instruction faults, invalid addresses, data overflow, null
pointers, and division by zero operations) during the operation of the MPU, you can solve the problem
in one of the following methods:
reboot: Rebooting the failed MPU so that the MPU restores to normal operational status.
•
•
maintain: Maintaining the current status of the failed MPU so that the system does not take any
restoration measures. Some software faults are hard to reproduce, and the printed information will
be lost after the firewall reboots. In this case, you can maintain the current status of the firewall,
facilitating fault location.
