YAMAHA YSP-4100 - YSP-5100

UPDATING FIRMWARE

When the following parts are replaced, the firmware must
be updated to the latest version by using the corresponding update method.

Updating the main microprocessor firmware - Main microprocessor (IC428, DSP P.C.B.), MAIN P.C.B.

Updating the DSP1 FLASH ROM firmware - DSP1 FLASH ROM (IC9, DSP P.C.B.), MAIN P.C.B.

Updating the Wireless Module Firmware and the AirWired microprocessor Firmware - AW-CARD P.C.B.

* The main microprocessor firmware and the DSP1
FLASH ROM firmware also can be updated by using the Firmware CD.

Confirmation of firmware version and checksum
Before and after updating the firmware, check the firmware version and checksum by using the selfdiagnostic function menu.
Start up the self-diagnostic function and select “18.ROM VER/SUM” menu.
Using the sub-menu, have the firmware version and checksum displayed, and note down them.
(See “SELF-DIAGNOSTIC FUNCTION”)
* When the firmware version is different from written one after updating, perform the updating procedure again from the beginning.

Initializing the back-up IC
Be sure to initialize the back-up IC after updating the firmware by the following procedure, otherwise the set up information (tuner preset, clock) can not be memorized properly.
Start up the self-diagnostic function and select “7. FACTORY PRESET” menu. (See “SELF-DIAGNOSTIC FUNCTION”) Select “7) PRESET RSRV” and turn off the power once and turn on the power again. Then the back-up IC is initialized.

# Preparation and precautions
# Download the firmware downloader program and the latest firmware from the specified source to the same folder of the PC.
# Prepare the above specified RS232C cross cable.
# While writing the firmware, keep the other application software on the PC closed.
It is also recommended to keep the software on the task tray closed as well.

Updating the main microprocessor firmware 

Connection
# Disconnect the power cable of this unit from the AC outlet.
# Connect the RS-232C terminal located on the rear panel of this unit to the serial port (RS232C) of the PC RS232C .

Operation procedure
1. While pressing the reset switch (SW801 of the FL P.C.B.) using a fine tipped pin, connect the power cable to the AC outlet.
The power to this unit is supplied and the microprocessor is in the writing mode.

2. Start up FlashSta.exe.
The screen appears as shown below. (Fig. 2)
3. Select the data to be transmitted and port. (Fig. 2)
# Select Program
Select Internal flash memory.
# RS232C
Select the port of RS-232C
# For selection of the port, COM1 to 4 can be used.
As COM5 or higher port cannot be used, select out of COM 1 to 4 of the setting on the PC side.

4. Click [Refer...] and select the firmware name.
Main microprocessor firmware: Y09_xxxx.mot
* The ID and MCU Type are loaded automati cally when the file is selected.  Click [OK].

5. Click [Setting], and set the baud rate.

6. Click [E.P.R.], then the “Erase” screen appears.
7. Click [OK] to start writing.

8. When writing of the firmware is completed, the screen appears as shown below. Click [OK].
9. Click [Exit] to end FlashSta.exe.

Updating the DSP1 FLASH ROM firmware
Connection
# Connect the RS-232C terminal located on the rear panel of this unit to the serial port (RS232C) of the PC with RS232C cross cable.
Operation procedure
* Before start, the power cable of this unit from the AC outlet.
1. Start up DSP_FLASHER_YSP2009.exe. The screen appears as shown below.

2. Select the data to be transmitted and port. Click [COMx], then the “COMx opened!” screen appears.
* The port selection varies depending on OS of the PC.
Windows 98/2000/Me ...................... COM1 – 4
Windows XP .................................... COM1 – 2
As port other than the above cannot be used, select the port using the setting on the PC.

3. Click [...] and select the firmware name. DSP1 FLASH ROM firmware: YSP09HIa_data1_verx_xxr.hex

4. Click [RDY] to set to the standby mode.

5. Connect the power cable of this unit to the AC outlet.
6. Start up the self-diagnostic function and select “16-3. UPDATE TI” sub-menu.
7. Press the “ENTER” key on the remote control to start writing.

8. When writing of the firmware is completed, the screen appears.
When the writing is completed succesfully, displayed checksum in “SUM from FILE” is the same as displayed checksum in “SUM from SET”.

9. Click [Exit] to end DSP_FLASHER_YSP2009.exe

Writing method using the Firmware CD
# Required Tools
#DVD or CD player
(with DIGITAL OUTPUT (OPTICAL or COAXIAL) jack)
#  Optical cable (when OPTICAL jack is used)
#  Digital audio pin cable (when COAXIAL jack is used)
# Firmware CD
#To make the firmware CD, download the latest firmware from the specified download source.

Connection
Connect this unit and DVD/CD player with DIGITAL OUTPUT (OPTICAL or COAXIAL) jack

Operation Procedures
While pressing the “VOLUME +” key of this unit, connect the power cable of this unit to the AC out let
The FIRMWARE UPDATE mode is activated and “F/W Upgrader” is displayed.

2. Press the “STANDBY/ON” key of the DVD/CD player to turn on the power.
3. Press the “EJECT” key of the DVD/CD player to open the disc tray.

* When the version of the firmware to be written is the same as the one existing in this unit, “Same Version”, “Please...” and “Power off!!” are displayed repeatedly. (Updating is not necessary.)
If the display remains unchanged for more than 10 seconds after starting the firmware CD play procedure, perform the firmware CD play procedure again from the beginning. If “FILE CORRUPTED” is displayed after “Address:XXXXXX”, make sure that the written data is not corrupted and perform Steps 1 to 7 of “Operation Procedures” again. If “Upgrade Failed” is displayed, perform “operation procedures” from the beginning.
6. Press the “EJECT” key of the DVD/CD player to open the disc tray.
