TMS320F28377D: Problem with generating .hex file

Green Deng

Part Number: TMS320F28377D
Other Parts Discussed in Thread: C2000WARE

Dear team:

The customer generates a hex file in Motorola S M3 format through "C2000 Hex Utility", but there is initialized const data in Page1 of the customer's project, so CCS generates two hex files for the program segment and the data segment.

1, Clients want to know, is this a must? Or is it possible to generate a hex file merging the program segment and the data segment by doing some configuration in CCS?

2, The customer also wants to know how to align and fill the bytes of the generated hex file? Can CCS be completed automatically, or must it be compiled and completed through a third-party tool?

Best regards,

Green

    You can do it by making changes not to the hex utility inputs, but in the linker command file.  Please see this forum post for details.

    It is probably better to do that by aligning and filling the output sections in the linker command file.

    Please let me know if these suggestions resolve the problem.

    Thanks and regards,

    Hi George:

    It is better to explain more about how to align and fill in the output sections in the linker command file.

    Best regards

    Please get some general background on linker command files by reading the article Linker Command File Primer.

    The key points from the forum post I referred to earlier are ...

    • Remove "PAGE 1" in the MEMORY directive
    • Change all other instances of "PAGE = 1" to "PAGE = 0"

    Regarding the linker command file you have now, where does it come from?  Does it come from C2000Ware?  Please let me know.  I'll refer this thread to the relevant team, so they can help you change the linker command file.

    Thanks and regards,
