Error Code Description |
Handling Suggestion |
|---|---|---|
7168 |
The PCB or BOM version is abnormal. |
Replace the board. |
7196 |
The flash is faulty. |
Replace the board. |
7199 |
APP active and standby areas damaged: In the off-chip flash, the active and standby areas of the APP are damaged, and the MCU cannot be started after being powered off. In this case, the system prompts the user to upgrade the MCU to update the active and standby areas of the off-chip flash. If the upgrade fails (the flash is abnormal), the system prompts the user to return the MCU to the factory to burn the off-chip flash. |
