TMS320C6748 Development Kit (LCDK)

Other Parts Discussed in Thread: TMS320C6748, OMAP-L138

Hello,

I am trying to startup the development kit TMS320C6748 Development Kit (LCDK).

I installed the Tera Term software.

The switches on the board (SW1) are set correctly.

I connected the board to PC by USB.

I reset the board, wait more than 10 seconds but I  don't see anything on Tera Term window.

Can anyone help me?

Sincerely,

Yacob.

    Hi Yacob,

    Option 1: Check the baudrate settings in teraterm. It should be 115200.

    Option 2: Check whether the FTDI drivers are properly installed in your PC.

    The following wiki page link has the required details about LCDK

    http://processors.wiki.ti.com/index.php/LCDK_User_Guide

     

    Thanks

    Hello Iyshwarya,

    Thank you for the link to LCDK_User_Guide and for your suggestions.

    Regarding to the two options:

    Option 1: The baud rate is 115200

    Option 2: The FTDI drivers are working properly. I checked it via the following way:

    - Win7 Devices window

    - Opening of FT232R USB UART driver

    - Hardware menu, two devices: USB Serial Converter and USB Serial Port

    - Both devices working properly.

    I appreciate if you have other ideas to send me.

    Sincerely,

    Yacob.

    Hello,
     
    I changed the DIP switch (SW1) from state "boot from NAND16" to state "boot from UART2".
     
    I powered up the board and on TeraTerm I saw: BOOTME
     
    It means:
    1) The USB serial port devices and Tera Term on the PC work properly.
    2) There is some problem on the board in "boot from NAND16" state.
     
    Should I copy/burn the NAND flash with bootloader and demo applications?
     
    Sincerely,
     
    Yacob.

    Hi Yacob Hassidim,

    You need to program the bootloader and demo applications.

    Please refer the below link:

    Hello Balaji,

    Thank you for your suggestion.

    I downloaded the finger print application and program (burn) on the board.

    The application runs properly.

    I didn't find the how to download bootloader.

    Can you please advise me where can I download the bootloader?

    Sincerely,

    Yacob.

    Hi Yacob,

    You have to install the C6000 BIOS SDK. After installation, in below path:
    C:\Program Files\Texas Instruments\c6sdk_02_00_00_00\tools\OMAP-L138_FlashAndBootUtils_2_36\OMAP-L138\GNU\ubl

    User boot loader binaries are there.

    -Thanks,
    Balaji N

    Hello Balaji,

    Thank you very much for your answers.

    I found the boot loader binaries in GNU\ubl directory.

    I understand that I should use: ubl_C6748_LCDK_NAND file (is it true?).

    Can you please explain the goal of the following boot loaders:

    - ubl_C6748_LCDK_NOR

    - ubl_c6748_LCDK_SPI_MEM

    I found the source code of facedetect demo oin the directory demos/facedetect

    Can you please advise me where are the source code of:

    - fingerprint demo

    -LCDK bootloader

    - flash demo

    Thanks again.

    Sincerely,

    Yacob.

    Hi Yacob,

    ubl_C6748_LCDK_NAND file is for NAND Flash memory.


    ubl_C6748_LCDK_NOR and ubl_c6748_LCDK_SPI_MEM boot loaders are to run in NOR Flash
    and SPI Flash memories.

    The finger print demo code is proprietary code owned by Authentec.
    We have ported it to the LCDK which integrated that sensor.
    To obtain this licensed software please contact TI third party Authentec directly.

    For UBL source, in link http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L138#Obtaining_the_software
    download this software and in path OMAP-L138_FlashAndBootUtils_2_40\OMAP-L138\CCS\UBL_ARM,
    code is available.

    -Thanks,
    Balaji N

    Hello Balaji,

    I am working on facedetect example from TI site but having issues getting beyond locating lcdk for this example.

    I have downloaded and installed "c6sdk_02_00_00_00' in the c: drive. In this directory, there are demos for facedetect, fingerprint, and flash as well as it_all_about_you. when I tried to import the facedetect example after selecting the lcdk folder, the CCS seems to not give me option to finish even though lcdk is selected. I have re-installed the downloaded "c6sdk_02_00_00_00" and tried again but that did not resolve the problem.

    Can you please let me know what to do from this point?

    Thanks in advace,

    Roland

    Hi Roland,

    Kindly post your queries in new thread as Verified Answered queries won’t get attention after the thread has been closed.

    For your question, Ensure whether you have imported your face detect demo from the correct path in CCS

    C:\Program Files\Texas Instruments\c6sdk_02_00_00_00\demos\facedetect\build\cgt_ccs\lcdk

    This path contains the project folder for importing the Face detect demo into CCS.
