RTA-FOUSB-MON User’s Manual Rev 2.2
C.5 Re-programming the ICD
This section discusses how to re-program the ICD if for some reason the user ROM firmware
was erased or damaged. A good indication that the ICD needs to be re-programmed is when
there is no yellow LED flashing, yet the red power LED is on.
The ICD has a boot mode that can be used to program the user ROM area. When the ICD
was shipped, the user ROM firmware was pre-programmed with firmware that can
communicate with the FoUSB Programmer and KD30 Debugger. However, in the event that
this firmware got erased or damaged, you can use this boot mode to re-program the ROM
firmware.

First unplug the USB Monitor board from both its target and from the USB cable.
Remove the black plastic case.
Shunt JP1 with a 2.54mm (.100 mil) jumper or using a bent paper clip, short the 2 hole
jumper labeled MCU Mode. This will configure the ICD to run in boot mode when it is
powered up.
Plug the USB cable back in. The ICD will now be in boot mode and will communicate as
a USB device to the PC. The ICD uses a different USB Driver than the USB Monitor
application, so we will need to load another USB Driver. The driver is located in
C:\MTOOL\FOUSB\USB Driver\.
Once the driver is loaded, open Flash-Over-USB again. Note that the MCU device name
displayed in green on the front screen will automatically change to M37641F8 without
having to select that device.
Also, a Load MMI button will appear on the right. Click on the Load MMI button and
select your target MCU device and let FoUSB re-program the ICD.
Remove the paper clip, unplug the USB Cable and enclose the board back into its case.
Now re-attach the ribbon cable to your target board and re-connect the ICD to your PC
with the USB cable.
If you plug the ICD into the PC, the FoUSB Programmer should show the target MCU
device name you selected earlier. If for some reason, it still does not come up, your ICD
may have been damaged. Please contact your Renesas representative to get a
replacement.
