Handling Process
Upgrade the software to version V100R001C01SPC100
Root Cause
1. Format the FLASH, and free space is still 8M.
2. Maybe the problem is about software version.
Suggestions
The old version would lock some FLASH space, so the free space is not the real free space. In this case, we need to upgrade the software version.
