Instructions to install and setup FDT Flash programming software

Having built or sourced an hardware interface, the next challenge is how program the ecu flash having done some changes to the firmware.

The software to do that is downloadable from the ecu processor manufacturer called renesas from the following address:

To download it you may need to register, but that is not a big deal... its freeware as they say.

Installation is easy like with any other windows software. Anyhow if you are using an USB based RS-TTL converter you may wanto connect that to your computer before starting to run FDT.

Basically your windows pc should recognize your new usb device when you just plug it in and install it ready to be used. Sometimes you may get a message that the device driver is not approved fow windows - but you should just ignore that.


The end result should be that you see the following message on your laptop:


In my case the USB driver installed to COM port 3, so you should spend some time and check what is the new port on your computer. Having found that out you should just proceed to install the fdt by double clicking the file you just downloaded from Renesas.

Installing FDT is easy, just click the windows OK, next or Finish when they appear and accept the default settings.


After the installation is complete, you start the FDT from Start menu of your computer like any other windows program. When it is started for the first time, the program asks for configuration information.

The first step is to choose FDT to generate a new project workspace by selecting the topmost radio button.

After that you name your project, I used name sh7052 which is also the name of the processor in the next screen which you can see below and pressed OK.


Then the FDT setup during first start asks you to select which is the processor. And by typing in 7052 you get a list from where you can choose the sh7052 like in the picture below.


Then you are asked to select the com port you use. If you are using the USB device you must have your USB converter connected at this stage, otherwise its not seen on the list.


For the rest you just answer Next or OK until the program is started and does not anymore ask anything.


The setup is complete when you see the main screen like below.

And thats it !
