5.3 Firmware Download Error
If the power is shut off during the self-check or firmware download for an unexpected reason, it
may happen that the system does not start up normally. In such a case, follow the procedure below
to download firmware one more time.
(1) Set the interface selection switch on the rear panel to "LPT". Then, connect the LPT parallel
interface cable to the emulator PC7501 and host machine.
(2) Within 2 seconds of activating power to the emulator PC7501, press the RESET switch on the
front panel to change its mode to maintenance mode.
(3) Start up the emulator debugger M3T-PDxxF.
(4) When a firmware download instruction appears on the emulator debugger M3T-PDxxF's
startup screen, follow the message to download firmware one more time.
During downloading, the ERROR system status LED flashes. This means firmware is being
downloaded, so it is not a fault of the system.
(5) The download requires approximately 90 seconds. When the download is completed, the
system automatically restarts and returns to the normal mode.
(6) Execute the self-check after turning off the power. The startup procedure in step (1) above is
provided for entering the special mode for maintenance purposes. Do not use this procedure unless
you are executing the self-check or downloading firmware.
5.4 Target Status Error in the Self-check
The emulator PC7501 checks the status of the emulation probe, firmware, and target MCU before
it starts the self-check. A target status error results if a fault is detected with respect to the
following three items:
(1) Connection to the emulation probe
(2) Matching of emulation probe and firmware
(3) Status of target MCU
If a target status error is encountered, check the following:

4.5 Self-check (P.35)
Is the emulation probe firmly plugged into the emulator PC7501's connector?
4.3 Connecting Emulation Probe M3xxxxTx-EPB (P.33)
Is the firmware matched to the emulation probe?
Execute the latest emulator debugger M3T-PDxxF. If the emulator debugger M3T-PDxxF
starts up normally (waiting for command input), firmware is not the cause of error. If a
firmware download instruction appears on the screen when you call up the emulator debug-
ger M3T-PDxxF, follow the message to download the firmware that is matched to the
emulation probe.
