TMS320C6742: Get started with TMS320C6742

Part Number: TMS320C6742
Other Parts Discussed in Thread: OMAP-L138

I've downloaded and installed both Code Composer Studio and the Processor SDK.

Under CSS > Window > Preferences > Code Composer Studio > Products, CSS detected the products and installed them for me.

I couldn't find anything on the Resource Explorer of CCS that uses the said device.

How do I actually start coding for TMS320C6742EZWT2 in C++?

Is there a development kit around TMS320C6742EZWT2?

What am I missing?

Thanks in advance.

  • Hi,

    Please refer to OMAP-L13x/C674x Resources and FAQ to get started with C674x development.

  • Dear Jianzhong,

    I ran the following pdkProjectCreate.bat command.

    This is the output:

    Please advice.

    Also, how does building the sample projects for OMAP-L138 work for C6742 DSP?

    If I get the OMAP-L138, could I connect this development board's JTAG to a target/custom board with C6742 for programming and debugging?

  • Hello,

    The error was most likely caused by CCS version mismatch. Please refer to this FAQ regarding how to create PDK example projects. It uses AM437x as an example but the steps apply for other device as well. As an alternative, you can simply  use the ProjectSpecs in omapl138_c6748_ccs_projectspecs.zip, as provided in  OMAP-L13x/C674x Resources and FAQ.

    Also, how does building the sample projects for OMAP-L138 work for C6742 DSP?

    When you run the script with argument "dsp", you'll generate sample projects for C674x DSP, which have "c674x" in the project names. Or you can find ProjectSpec in the above zip file for C674x, for example, omapl138_c6748_ccs_projectspecs\ccs_examples\windows\OMAPL138\GPIO_LedBlink_lcdkOMAPL138_c674xTestProject.projectspec.

    If I get the OMAP-L138, could I connect this development board's JTAG to a target/custom board with C6742 for programming and debugging

    Yes, as long as you also get the compatible external emulator, you should be able to connect to C674x DSP through CCS and start your development.

    Regards,

    Jianzhong

  • Dear Jianzhong,

    I can import and open the projects from the omapl138_c6748_css_projectspecs.zip. 

    I'll go ahead and close this support ticket while waiting for my XDS200 and OMAP-L138 to arrive.

    Will post another support ticket when I dive deeper.

    Best regards,

    Daniel
