TMDX570LS31USB with "a memory region that is not writable"

I am using CCS 5.4.0.00091 with TMDX570LS31USB USB stick. The following message was shown when compiling the demo program provided by TI, what does it mean?

CortexR4: GEL Output:     Memory Map Setup for Flash @ Address 0x0CortexR4: Loader: One or more sections of your program falls into a memory region that is not writable.  These regions will not actually be written to the target.  Check your linker configuration and/or memory map.

I uploaded the system link file for your reference. I am using the demo program directly from C:\ti\Hercules\Hercules Safety MCU Demos\TMS570LS3x_target_sources\

It's the first time I am using CSS with TI evaluation board and thanks for your help!

    Hi Eric,

    There is no problem with the memory mapping in the cmd file used in the demo project. I just compiled the demo project and loaded it to the flash without any problem.

    Can you please disconnect the JTAG, and unplug/re-plug the usb stick? If the problem comes again, please send me the map file which should under debug folder.

    Thanks and regards,

    Hi QJ,

    This problem occurred since the first time I am programming for this USB stick and unplug the usb stick cannot solve this problem.

    I found two .map files under the "C:\ti\Hercules\Hercules Safety MCU Demos\TMS570LS3x_target_sources\build\Debug" and I already uploaded them. Thanks for your help!

    Hi Eric,

    1. Can you please try to run from RAM? After target is connected, using the scripts to swap the flash and the ram.

    2. For using flash, the On-Chip Flash under Tools shows several erase options:

    • Entire Flash
    • Necessary Sectors Only (for Program Load)
    • Selected Sectors only <- when you select this one it enables some more options for selecting which banks to erase

    Is there any problem to erase the flash?

    Regards,

    QJ
