    XMC4500: DSRAM_1_system overflowed

    Hello at all,

    I have a big problem. I have added some variables to my software and then I get some problems (see attachment).

    Hi,

    You could modify the linker file to locate the .bss section or part of it into the DSRAM_2_comm region.

    The linker script linker_script.ld is located in your main project folder.

    If you are new to linker scripts: You need to adjust both the linker script and your code to place some parts of the RAM to a new location. For example, to place the following integer array to the DSRAM2_comm, add attribute:

    Code:
    __attribute__((section(".ram2content"))) unsigned int addData[1024];
    In linker script, add the following line in the DSRAM2_comm region after alignment line:

    Code:
    *(.ram2content)
    I currently have no access to a XMC4500 project, hope it works ...
