CCS/TMS320F28069: issue with configuring FT2232D on 28069 controlSTICK

Part Number: TMS320F28069

Tool/software: Code Composer Studio

I have been working on the EVB to develop my c code.

Now I designed a new PCB with similar schematic (but no EEPROM for FT2232) and trying to download the firmware into PCB. Before that, I firstly configured FT2232D, channel A as JTAG for code download, channelB as COM port for data transfer when program is running.

I use Labview to realize the function below

FT_Open(0, &ftHandle)  // 0 for channel A I guess
FT_SetBitmode (ftHandle, 0xff, 0x2)   // set IOs to output; set MPSSE mode
FT_Close(ftHandle)

I got the correct return value. Now I am trying to download firmware in CCS, but failed with Error connecting to the target

I think I have successfully set the FT2232 with channel A as JTAG port and channelB as COM port. I am using the same CCS project code for this PCB as for controlSTICK EVB. I did the CCS downloading right after finishing setup FT2232 without power off or any other operation. 

I am not sure if there is any step missing? Is the config process correct for FT2232, are values set in the above functions correct? Do I need to do any changes to the CCS project? Please help

Thanks,

Ning

    Hi Ning,

    Have you made any progress since your post?

    ===

    Why did you remove the FT2232's EEPROM?  The EEPROM gets read at FT2232 bootup to determine the VID/PID (and therefore impacts which driver Windows may use for interfacing).  This information would then get lost once powered-down, if not do other things (I'm not an expert on this FT2232 chip when used in this way).

    When you try to connect via CCS, what FTDI/XDS100 entries do you see in Device Manager?


    Thank you,
    Brett

    I am not using FT2232 for programming now. Instead I bought a XDS100V3 debug box. I only use FT2232 for data transfer as a USB-to-UART converter. It works perfectly.
