IWR1642BOOST: some questions about IWR1642‘s BSS

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642

IWR1642 configured the BSS waveform parameters and called the function of MmwaveLink_sensorStart,and BSS starts working normally and sends waveform. Now I do the software reset of IWR1642 without power loss, and BSS is still working.

MSS or DSS reperforms the initialization operation due to reset, executes the function of MmeaveLink_initLink, and the return value of this function is normal. But when the function of MmwaveLink_getRfBootupStatus is executed later, MSS falls into a dead loop and cannot read the BSS state. Is it because BSS is working at this time?

Calling a function of rlDevicePowerOff and rlDevicePowerOn after attempting to do so has the effect of restarting BSS, but is not effective. So I had to disconnect and repower the development board every time to continue debugging. What function can restart BSS after reset.

Thanks a lot！

    Hi Y Gu,

    I need some clarification on a few items.

    Can you clarify what you are doing when you do software reset of WIR1642 without power loss? Also how do you confirm BSS is still working?

    Do you know where in MmwaveLink_getRfBootupStatus the code is hanging?

    Lastly, would you clarify what you mean when you say the effect of rlDevicePowerOn is not effective?

    Please clarify these points and we can continue the discussion.

    Regards,

    AG
