    Hi,

    I would like to know if you are proceeding with a NOR Flash, what is your sequence of operations to be performed.

    Are you going to use the NOR flash to boot?

    Or are you just going to use the NOR Flash at the application level post booting is performed? or both.

    Apart from this, I would like to tell you that based on the software buildsheet for AM62A, it is mentioned that we currently support OSPI NOR Flash for bootloader operations but not for memory interfaces, so the support is limited when it comes to NOR Flash.

    NOTE: Currently we do have support for NAND flash on WKUP R5 and MCU R5 on AM62A MCU PLUS SDK front.

    Regards,

    After the Wakeup R5F boots up, the MCU R5F uses NOR Flash to do NvM at the application level to store information such as Dtc.
    And in the MCU R5F, Norflash will be used to implement its AB upgrade. That is, the program of MCU R5F is stored in Norflash.

    Please clarify the terms NvM, DTC and AB upgrade used in the above context.

    Currently I am seeing that your use case is to use the NOR Flash from MCU R5F at application level.

    This is not supported as per the software buildhseet.

    But the drivers to use NOR Flash does exist, so you can go ahead and give it a try.

    A step by step process would most probably be, making sure to enable NOR Flash in the MCU R5 Application's SysConfig which you are going to use.
