Unable to flash


Hi all,

I have problems with the flashing of the Gsxr k9 750. I have an connection with the ECU in terms of reading data monitoring screen. 

But when I want to flash I get the following message;

"Could not set Com port parameters. Programming aborted, set correct com port for the interface using data monitoring screen"

Looking at the coding of the program it is being caused by;

   FT_status = FT_Open(cp, lngHandle)
        FT_status = FT_ResetDevice(lngHandle, 3)                                'set device to default status
        FT_status = FT_status + FT_Purge(lngHandle)                             'clear rx and tx buffers
        FT_status = FT_status + FT_SetBaudRate(lngHandle, 57600)                'set speed 57600
        FT_status = FT_status + FT_SetDataCharacteristics(lngHandle, 8, 1, 0)   ' 8bits ,1 stop, parity none
        FT_status = FT_status + FT_SetTimeouts(lngHandle, 5, 5)               'rx and tx timeouts ms
        If FT_status <> 0 Then
            MsgBox("Could not set Com port parameters. Programming aborted, set correct com port for the interface using data monitoring screen")
            B_FlashECU.Enabled = True
            FT_status = FT_Close(lngHandle)
            Return

I have no idea what causes this. What can I try to get rid of this message en finally get some flashing action or even show me the failing step so I can dig further.

I use the interface from boostbysmith (v2.0)

Try it with the USB TO UART(TTL) SERIAL CABLE without the whole interface! Maybe your interface has an issue.

So finally I found the problem; I am running windows 10 in full administrator ect. After plugging in the FTDI it installes the new (latest) drivers for the FTDI, even running the FTDI install function of ECUeditor does not installs the correct needed version of FTDI. The latest driver from windows is too new and the ecueditor is to old for windows 10 to activate the correct functions?

After finding the driver of the FTDI in de map structure (under common) and installing it stand alone with administration rights it works like an charm.

Still weird that data stream of reading works and flashing fails....
