Can't write data to OMAP-L138 Development Kit

Other Parts Discussed in Thread: OMAP-L138, CODECOMPOSER

I've tried several times to load a simple program to the OMAP-L138 Development Kit with CodeComposer Studio, using an XDS100v2 USB JTAG Emulator. I have included here the error message that CCS gives.


C674X_0: Trouble Writing Memory Block at 0x20 on Page 0 of Length 0x1c00: (Error -1190 @ 0x20) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.520.0)

I'm using the linker.cmd file provided by LogicPD for my board. It's also attached for reference.

I really don't know what the correct numbers are in the linker file. Can someone confirm them, or suggest other possibilities as to what might be going wrong?

    Hello,

    Your linker command file looks fine. It is putting everything into shared ram. But the error you got was a write error at:

    Rudolph Raab said:
    C674X_0: Trouble Writing Memory Block at 0x20 on Page 0 of Length 0x1c00: (Error -1190 @ 0x20)

    Which is in non-accessible memory. Could you provide the generated memory map file? It should be in the same location at the *.out file, with a *.map extension.

    Thanks

    I've attached the memory map file. Thank you for your attention.

    The contents in your linker command file does not line up with the content in your map file.

    command file:

    -----

    MEMORY
    {
       dsp_l2_ram:      ORIGIN = 0x11800000  LENGTH = 0x00040000
       shared_ram:      ORIGIN = 0x80000000  LENGTH = 0x00020000
       external_ram:    ORIGIN = 0xC0000000  LENGTH = 0x08000000
       arm_local_ram:   ORIGIN = 0xFFFF0000  LENGTH = 0x00002000
    }

    SECTIONS
    {
       .text       > shared_ram
       .const      > shared_ram
       .bss        > shared_ram
       .far        > shared_ram
       .switch     > shared_ram
       .stack      > shared_ram
       .data       > shared_ram
       .cinit      > shared_ram
       .sysmem     > shared_ram
       .cio        > shared_ram
    }

    ----

    As you can see above, your code (.text) is supposed to be placed in shared_ram starting at 0x80000000. But your map file says:

    -----

    .text      0    00000020    00001c00     
          

    -----------

    Your program is built for your code to be placed at 0x20.

    Somehow the linker command file was not used to build your project. Can you double check your project settings?

    Thanks

    Thank you for your prompt reply. I will re-check the project properties when I get back into work tomorrow morning, around 8:00 AM (US Eastern Time). I'm glad the linker command file is correct; I'll find out why CCS isn't using it.

    That solved it. When I initially created the project, I had selected the linker command file. However the project somehow forgot about that setting.

    Thank you for your assistance.
