5.13.3 Functions
[A] Clearing update error flag (Clear Error Flag in Software Installation)
Even if the firmware downloading has been completed normally, the Recovery Mode may accidentally
start up and an F600 error occurs when the power is turned ON again. In this case, clear the Update
Error flags used in the download process with this function. (Normally, the flags are automatically
cleared in the download process.)
Also in the case the Recovery Mode accidentally starts up after the replacement of SRAM on the SYS
board, the flags are cleared with this function.
[B] Formatting data storage partition (Format Root Partition)
When a defect occurs on the UI data, etc. which are stored in the HDD, the partition with the stored UI
data, etc. is formatted with this function.
Do not use this function since it is not normally necessary. HDD data must be installed after performing
this function.
[C] Creating HDD partition (Format HDD)
When the HDD is replaced or UI data, etc. are downloaded using the USB storage, it is necessary to
format a partition in the HDD before downloading. In this case, the partition is created in the HDD with
this function.
Notes:
• When downloading with a download jig, it is not necessary to format a partition in advance.
• Perform the HDD partition formatting only when a new HDD is installed since all data in the
current HDD are erased by this operation.
• When this operation has been done, do not perform SRAM data formatting (Clear SRAM) before
the normal start-up.
[D] Formatting SRAM data (Clear SRAM)
When SRAM is replaced with a new one, abnormal values may be written in the new SRAM. SRAM
data must be formatted with this function for such case.
Notes:
• This function is required only when a new SRAM is installed.
• Do not perform this function in cases other than the installation of a new SRAM because all data
in the SRAM will be deleted with this function.
• When this operation has been done, do not perform HDD partition creation (Format HDD) before
the normal start-up.
