CCS/TMS320DM8127: How to write code for DM8127, need a step by step tutorial.

Part Number: TMS320DM8127
Other Parts Discussed in Thread: CCSTUDIO

Tool/software: Code Composer Studio

I want to build a vision module using DM8127, I've successfully booting up and streaming. However, I confuse about how I coding for it. Can I code directly on it like a computer or I use CCS to load code. I've read about IPNC, but it is a vague guide. I need a step by step tutorial about writing code for it, for example: how to capture image and store the image, thanks.

  • I've tried to create a CCS project, however, when I choose connection that XDS100v2 or v3 and Verify. I got this error

    [Start]

    Execute the command:

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

    [Result]


    -----[Print the board config pathname(s)]------------------------------------

    /home/sang/.ti/ti/1/0/BrdDat/testBoard.dat

    -----[Print the reset-command software log-file]-----------------------------

    This utility has selected a 100- or 510-class product.
    This utility will load the adapter 'libjioserdesusbv3.so'.

    An error occurred while soft 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 '-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.

  • Sang,

    Do yo use TMDSCSK8127 Evaluation Module?

    DM8127 camera starter kit (CSK) contents:
    • TMDSCSK8127 module
    • CSK carrier card
    • Camera module (LI-CAM-AR0331-324-1.8) with FPC cable

    DM8127 CSK comes with XDS100v2 on board emulator, located at CSK carrier card. You need to connect USB cable to Micro USB connector J11.

    Regards,
    Pavel
  • Yes, I use TMDCSK8127 Evaluation Module with full options as you list above.

    I have rewrite the sdCard, following: processors.wiki.ti.com/.../IPNC_RDK_DM38x_,_DM8127

    Is this effects any thing to the connection ?
    Thanks,
  • Sang,

    No, SD card can not impact JTAG connection. You should be able to connect your DM8127 board to JTAG with and without SD card.

    Check if you have below emulation package installed.

  • I already installed XSD Driver, but the problem wasn't solved.
  • I get out of stucking in :
    The value is '-151' (0xffffff69).
    The title is 'SC_ERR_FTDI_OPEN'.

    problem.

    But I am heading to the other:

    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).

    -----[The log-file for the JTAG TCLK output generated from the PLL]----------

    There is no hardware for programming the JTAG TCLK frequency.

    -----[Measure the source and frequency of the final JTAG TCLKR input]--------

    There is no hardware for measuring the JTAG TCLK frequency.

    -----[Perform the standard path-length test on the JTAG IR and DR]-----------

    This path-length test uses blocks of 64 32-bit words.

    The test for the JTAG IR instruction path-length failed.
    The JTAG IR instruction scan-path is stuck-at-ones.

    The test for the JTAG DR bypass path-length failed.
    The JTAG DR bypass scan-path is stuck-at-ones.

    You should ask/post this type of questions (relate to JTAG, Emulation) in CCStudio forum:
