Upgrading BootRom of Slave MPU Fails Because Realtime Backup of Master and Slave MPUs is not Implemented

Publication Date:  2012-07-27 Views:  55 Downloads:  0
Issue Description
Version: NE5000E-VRP5.30-220039.11
Phenomenon: During the upgrade of NE5000E,  after the slave MPU is upgraded, the switchover is performed. When the board is registered, upgrade former master MPU with upgrade slavempu startup; however, upgrading BootRom fails. The upgrade succeeds with upgrade slavempu jtag startup bootrom.

Handling Process
Use upgrade slavempu jtag startup bootrom to finish the upgrade of BootRom.
Root Cause
During online upgrade, NE5000E has to check the backup status of master and slave boards. If realtime backup of master and slave MPUs is not implemented, the upgrade is incomplete. Refer to the print informationduring upgrade failure: Waiting for the state of realtime or routine backup! There is no need to check whether realtime backup of master and slave MPUs is implemented with JTAG. The upgrade of BootRom can be complete.
Suggestions
      The solution is as follows:
1. Upgrade with jtag. (The time is long. The CPU usage of MPU is increased and the service is influenced. It is not recommended.)
2. After the realtime backup of master and slave MPU boards is complete, upgrade BootRom normally. It is recommended.
