12.4 Installing a Patch on the MPU
12.4.1 Establishing the Configuration Task
Applicable Environment
When required to make up the defects of the MPU, you can install a patch on the MPU.
Through installing a patch, you can upgrade the system without upgrading the system
software.
When a patch is uploaded, the system checks that the patch version is the same as the system
version. If the two versions are not the same, the system prompts that the patch uploading
fails.
Before installing a patch on the MPU, you need to check the running of patch on the master
and slave MPU s. Otherwise, the patch becomes invalid after the master/slave switchover.
Pre-configuration Tasks
Before installing a patch on the MPU, upload the patch to the root directory of the Flash
Memory of the master and slave MPUs.
