PC7501 User's Manual
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.
4.4 Downloading Firmware (P.36)
(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.
4.5 Self-check (P.37)
5.4 Target Status Error in the Self-check
The emulator PC7501 checks the status of the emulation probe M3xxxxTx-EPB or R0ExxxxxxEPB00, 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:
4.5 Self-check (P.37)
(1) Connection to the emulation probe M3xxxxTx-EPB or R0ExxxxxxEPB00
(2) Matching of emulation probe M3xxxxTx-EPB or R0ExxxxxxEPB00 and firmware
(3) Status of target MCU
If a target status error is encountered, check the following:
□
Is the emulation probe firmly plugged into the emulator PC7501's connector?
T
□
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 debugger
M3T-PDxxF, follow the message to download the firmware that is matched to the emulation
probe.
