SYS/BIOS memory map

Other Parts Discussed in Thread: SYSBIOS

Would like to know the memory map used by SYS/BIOS specific sections. Would be interesting to know the split of SYS/BIOS sections across LI-P and L2 memory and its impacts on the performance. Thanks!

    You can change or add memory map settings (like linker command file) in CCS for SYSBIOS code.

    CCS Debug view -> Tools -> RTSC Tools -> Platform -> Edit/View or New

    Also you can customize the existing memory map.

    If it not answered your question, could you elaborate a bit on your requirement please.

    You can look at the <project>.map file in your project's Debug or Release folder to see where various sections were placed. Also, there will be a linker .cmd file somewhere that will show you how various sections are intended to be loaded.

    L1P is usually 100% cache, so SYS/BIOS would not use any of it directly.

    The use of L2 is dependent on your settings in the files as described by Titus.

    Yes, CCS helps in memory map setting for SYS/BIOS. Since I am using SYS/BIOS for the first time hence wanted to understand the existing map generally used for SYS/BIOS kernel memory sections. Would it be possible to provide the snapshot of the map file for SYS/BIOS specific sections? Thanks!

    You will want to refer to the SYS/BIOS User Guide or online documentation to understand the various sections created by and used by SYS/BIOS.

    If you will build any sample project that uses SYS/BIOS, you can look at the <project>.map file in your project's Debug or Release folder to see where various sections were placed.

    If you need more support for SYS/BIOS, please post a new thread in the TI-RTOS E2E forum. That is where the SYS/BIOS experts are working.
