    Thread Summary
    
                The user asked how to generate a memory map file for the ARM core on the SC-584 EZ KIT. The solution involves adding the linker option '-Wl,-M=ARMcode.map' to the project settings. The user also inquired about the difference in uC/OS memory footprint between DEBUG and RELEASE modes, noting a significant reduction in RELEASE mode. The engineer confirmed that this is expected due to optimizations and that uC/OS footprint on ARM core is larger compared to SHARC core due to different architecture and implementation.

    Hi all,
    
 
    I have to analyze the memory utilization of my application for ARM core on SC-584 EZ KIT.
    
 
    We know that we can generate the memory map file for SHARC cores by enabling the linker options "Generate symbol map (-map)" in SHARC core project. We are not finding any such options for the ARM cores. Can someone suggest about generating the memory map file for ARM core?
    
 
    Thanks

        Hi Harshit,
        
 
        I have small doubts regarding the uC/OS memory footprint of ARM core on SC 584 EZ kit. Its mentioned in the CCES help note that memory footprint for basic project is around 68596. When I am analyzing footprint using the tool you have mentioned, there I am getting almost same value when I am building the project in DEBUG mode. 
        
 
        Where as in RELEASE mode I am getting the almost half. Just want to confirm why there is so much difference.
        
 

        When we see the footprint of uC/OS on ARM and SHARC core, the values are almost double for ARM core. My question here is, why the uC/OS takes that much of footprint on ARM core?
        
 

        
 
        Awaiting for your response.
        
 
        Thanks
