    Please name the versions you are using of BIOS and Code Composer Studio. Also, please name the device you are using. We will likely point you to training opportunities to learn how to use BIOS / TI-RTOS and Code Composer Studio.

    This software tools question belongs in the TI-RTOS Forum for software tools questions instead of this Keystone Multicore forum for hardware and device-specific questions. Also, you should not be using the old DSP/BIOS with a new Keystone device. A Moderator will move this thread this time.

    Thanks for the additional details.

    The linker command file will be automatically generated, with some default placement of memory sections, into the pre-defined memory segments.  You can change the placements either using the graphical configuration tool, or by text modifications to the .tcf file, and then rebuilding the project. 

    The different memory configuration parameters are described in the MEM module description in the API guide (for example, section 2.17 in http://www.ti.com/lit/ug/spru403s/spru403s.pdf).  I think the information you are looking for is there...
