CCS/TMDSPREX28335: Pheripheral explorer kit not connecting to ccsv4

Part Number: TMDSPREX28335
Other Parts Discussed in Thread: TMDSCNCD28335, , TMS320F28335

Tool/software: Code Composer Studio

 I was trying to connect my TMDSPREX28335 kit to my hardware experiment. So I dumped my program on to the kit via CCSV4, after dumping the program I took the kit and connected a 5V supply and tried to connect to my hardware setup but eventually was not able to get any signal out of the kit. So I tried again to dump the program on the kit again but this time I am unable to connect it to the CCV4 and the following error is displayed also the tms320f28835 chip on tmdscncd28335 card is getting very hot on connecting to the laptop.

the value is '-151' (0xffffff69).
The title is 'SC_ERR_FTDI_OPEN'.

The explanation is:
One of the FTDI driver functions used during the connect
returned bad status or an error. The cause may be one or
more of: no XDS100 is plugged in, invalid XDS100 serial number,
blank XDS100 EEPROM, missing FTDI drivers, faulty USB cable.
Use the xds100serial command-line utility in the 'common/uscif'
folder to verify the XDS100 can be located.

  • Anurag,

    This application note: http://www.ti.com/lit/spracf0 has the steps and locations of the files to re-program the FTDI to become the XDS100 emulator.

    I would also look at the schematic, JP1 and SW1 as those determine if the power for the board is sourced from the USB connection or an external 5V supply.

  • I hope you're asking for a guide that came with TMDSPREX28335 

    also I noticed that when I switched on the kit, I kept the switch SW1 in USB position while connecting to 5V supply and after few minutes TMS320f28335 chip on the control card started to get hot. Due to this I disconnected the 5v supply and tried to connect the kit to my laptop wtmdsprex28335.pdfhich was not identified by ccsv4. Also prior to this everything was working fine.

  • I would like for you to not insert the control card into the PREX kit and just connect the USB with SW1 positioned to connect 2/3.  After you do this, if you open windows device manager, do you see the XDS100 in the device list?

    The previous lit# I had posted is not the same document that came with the PREX, but a universal JTAG debug guide.  If we do need to reprogram the FTDI, the links to how to do this are in that doc.

  • Anurag,
    Wanted to see if you had a chance to try the last debug step I posted?

    Best,

  • As per your suggestion, I took the card out and connected the board to my laptop. After that, went to the device manager but was unable to find XDS100. Also, I noticed that the led LD3 is not glowing when  connected to the laptop

  • Anurag,
    OK, it looks like the FTDI chip is not programmed correctly or not working as the XDS100v1 emulator. In the debug guide I referred to in the post above, there is a link(bottom of page 7)to the guide of how to manually re-program the FTDI back to a known state.

    Please go through these steps and let me know if you can see the emulator in the windows device manager.

    Best,
    Matthew
  • Anurag,
    Wanted to see if you had a chance to re-program the FTDI chip per above. Let me know if this has resolved things on your end. I'm going to mark TI Think Resolved for now, but please feel free to reply back if we need to continue the debug.

    Best,
    Matthew
