Hi experts,

I want to disable j7-mcu-r5f0_1 running in LOCKSTEP mode. Could you give me some tips about that?

Thanks,

Hutian

  • Hello Hutian,

    TRM: https://www.ti.com/lit/ug/spruil1a/spruil1a.pdf?ts=1593489575070
    CTRLMMR_MCUSEC_CLSTR0_CFG Register tells us whether the device
    has the mcu-r5fs in lockstep mode or not.

    0x9 => LockStep enabled..
    and in LockStep mode
    0x8 -> LockStep capable, in Split-mode
    0x0 -> always Split-mode

    By default mcu-r5fs are in lock-step mode. If your device reads 0x9 for CTRLMMR_MCUSEC_CLSTR0_CFG
    then it will be in lockstep mode as ROM brings up mcu-r5fs in lockstep mode.

    If this answers your query, then please resolve the thread.

    Regards,
    Keerthy

    Hi Keerthy,

    Can i wirte the register of CTRLMMR_MCUSEC_CLSTR0_CFG with 0x8 to make mcu-r5fs running in Spilt-mode ,if i read the value is 0x9?

    Thanks,

    Hi Hutian,

    The first code to execute is RoM code that will see this as lockstep enabled sample. So the answer is
    that it is not possible. Please resolve the thread if you do not have any further questions.

    Best Regards,
    Keerthy
