FIRMWARE UPDATE

5.4.3 FILE ARRANGEMENT

How the Program Works

The firmware-update program of Model J-P3 searches the folder romdata for
necessary firmware. When you save the firmware in a SD card, make the folder
romdata. You must not make the folder romdata in another folder; but you can
make more than one folder in the folder romdata. The firmware-update program
searches all folders if they are in romdata.
Each firmware program contains the file information. Before downloading the
firmware from an SD card, the firmware-update program reads the file information.
The firmware is downloaded only when the file information is correct.
NOTE: The file information can identify the firmware, but this information does not
guarantee that the data is not corrupted.

Example

When you save the firmware, we recommend
that you arrange folders and files as follows:
• In the folder romdata, make another folder
and use this folder exclusively for one model.
Use the machine code as the name of this
folder.
• When you save the firmware of a different
model, make a new folder in the folder
romdata. Give it a name as mentioned
above. (The diagram shows an example.
The folder romdata has three sub-folders:
B130, B149, and G106. Each folder is for
one model.)
• 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.)
