[F/W Upgrade Method]
When upgrading of the F/W becomes necessary for bug corrrection
and others, perform upgrading as described below.
1. Copy the following files into the destination that is immediately
below the Memory Stick Duo drive.
(The following files will be distributed as necessitated when
bug fix becomes necessary.)
• ldrasm.mot (Upgrade driver)
• CHIPEXEC.MOT (F/W of the product)
• update.pls (Upgrade MS identification file)
2. Insert the Memory Stick Duo that is prepared in step 1 into
the Memory Stick slot of the product. Then turn on the power.
(Use either a new battery or the AC adapter.)
3. While the screen showing the access menu is being displayed,
leave the machine as it is. The OPE-LED (red) lights on and it
turns off after about one minute.
Then remove the battery or disconnect the AC adapter. Remove
the Memory Stick Duo. This completes the F/W upgrade. Use
the test mode to check the version number of the F/W.
4. Once the upgrading is executed, the update.pls file will be
automatically deleted.
If you want to repeat the F/W upgrading, copy the update.pls
file again in the Memory Stick Duo.
Supplementary information:
If you want to a great many number of products, copy the
testmode.ind file additionally that enables repetition of the
upgrading.
• ldrasm.mot (Upgrade driver)
• CHIPEXEC.MOT (F/W of the product)
• update.pls (Upgrade MS identification file)
• testmode.ind (Special file to be used in assembly factory)
Note: Never turn off the power while upgrading is in progress. If the power
is turned off or if the Memory Stick Duo is removed while the
upgrading is in progress, the upgrading will end with failure. (It can
result in defective operations such as power cannot be turned on, or
operation becomes strange.)
In such a case, the product must be disassembled and the upgrading
is required. Please contact us for more details in such a case.
The following files can be created by creating an arbitrary text file
and by changing the file name.
• update.pls (Upgrade MS identification file)
• testmode.ind (Special file to be used in assembly factory)
