5. System Maintenance Reference
When you save the firmware, we recommend that you arrange folders and files as follows:
• In the folder romdata, make only one folder and use this folder for one model. Use the machine
code as the name of this folder.
• When you save some files other than firmware, make a new folder outside romdata. Save the files
in this folder. Do not save any file outside the folders. (The diagram shows an example. Three
folders, log, nvramdata, and prt, are outside romdata. These folders can store debug logs,
NVRAM data, and captured files respectively.)
