AM2431: The "Region No" of TRM "4.8.1 Memory Layout/MPU" is unknown.

Part Number: AM2431


Tool/software:

The TRM refers to spruim2g.pdf.

I have four questions about the region numbers in Table 4-60 "Memory Layout/MPU" in TRM "4.8.1 Memory Layout/MPU".

- Does it have anything to do with the "Region" described in Chapters 2 and 3?
- How do you set the Region, or is it fixed and does not need to be set?
- What Does the Region setting affect/work on?
- Are there any examples of How to use it?
- If there are any samples included in the SDK, could you please tell me the file path?

Thank you in advance for your help.

    Hello ,

    Users don't need to take care of these memory region settings in the MPU settings.

    By default all MCU+SDK examples configure all memory regions like OSPI, MSRAM, TCM and for ROM, users can't access this memory location in the application.

    The ROM bootloader runs on this memory location. So, the user can't configure the MPU region.

    Please look at any example and open syscfg ,and check for MPU region settings .

    Regards,

    Anil.
