Hi,


I am trying to allocate memory in L1 mem_block1_bw.  The LDF utility allocates memory from mem_block0_bw  when I create a heap on L1.  My memory map shows that there is available L1 memory in block1.  How do I access it?

    Specifically looking for method to dynamically allocate memory in 
    

    seg_l1_block1.
    

    I can declare a section using the following:
    

    #pragma section("seg_l1_block1")
    

    But this does not allow for dynamically allocating memory structures.
    

    Is there a method to define a heap for seg_I1_block1 and use heap_malloc(heap number, ....);?

    Hi Steve,
    

    As per your requirement, we have modified the app.ldf file for allocating the heap to l1-mem_block1_bw. Please find the attached "app.ldf" file for your reference.
    

    And refer to the screenshot for the heap allocation updated in-memory map file.
    

    Also please note that any hand-edits you make within the LDF file in a Source Window should be made within the generated $VDSG sections, to preserve them if/when the LDF is automatically regenerated by the tools.
    


    Below is an example:
    

    /*$VDSG<insert-......> */
    /* Text inserted between these $VDSG comments will be preserved */
    /*$VDSG<insert-.....>
    

    

    Regards,
    Nishanthi. V
