CCS/TMS320F28335: HVMP example won't load to the F28335

Part Number: TMS320F28335

Tool/software: Code Composer Studio

how should I troubleshoot this? I checked out the .out file and it is unreadable? I have also done a connectivity (right click/properties/verify -using ccsv6) test but I got the following error,

[Start]

Execute the command:

%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -F inform,logfile=yes -S pathlength -S integrity

The scan-path will be reset by toggling the JTAG TRST signal.
The controller is the FTDI FT2232 with USB interface.
The link from controller to target is direct (without cable).
The software is configured for FTDI FT2232 features.
The controller cannot monitor the value on the EMU[0] pin.
The controller cannot monitor the value on the EMU[1] pin.
The controller cannot control the timing on output pins.
The controller cannot control the timing on input pins.
The scan-path link-delay has been set to exactly '0' (0x0000).

An error occurred while hard opening the controller.

-----[An error has occurred and this utility has aborted]--------------------

This error is generated by TI's USCIF driver or utilities.

The value is '-150' (0xffffff6a).
The title is 'SC_ERR_FTDI_FAIL'.

The explanation is:
One of the FTDI driver functions used during
configuration returned a invalid status or an error.

[End]

this doesn't make any sense because I have reinstalled the FTDI driver...unless there is a setting I need to change in the code....but that shouldn't matter since I'm using an TI example, right?

any suggestiions, I'm sure it is not he FTDI driver. what are the EMU[0], EMU[1] pins?

  • HI Jose,

    I don't think this error has anything to do with the example you are trying to load but with the JTAG connection. Did you try loading any simple code? Also EMU0/EMU1 pin related message is just info. If this is board designed by your team then you need to probe all the JTAG pins on board to make sure these are functioning properly.

  • I don't think it is the JTAG connection because I've done the led example before and the simple code load up correctly.
    For the frequency test (under debug configurations), the pin set is GPIO0, should I change to a different pin when working with the F28335?
    I have also changed JTAG connections as well as F28335 boards.
    the F28335 board I am working with is straight from TI; I am not using any custom boards or modified the TI docking station and/or board.

    any other troubleshooting steps?
    Jose
