AWR2944: There is a possibility of failure when using Mibspi to write PMIC parameters.

Part Number: AWR2944

Tool/software:

Hello, experts

I am encountering a potential issue where writing PMIC parameters using mibspi occasionally fails.

I used the method from the example in the SDK mmwave_mcuplus_sdk_04_02_00_03 (via mibspi) to configure the enabling of the PMIC. Afterward, I performed a read-back and comparison and found that there is a small probability of failure.
The failure rate is low, and the majority of operations succeed without issues.

Could you please explain why there is a risk of failure when using this method? Additionally, how can this risk be mitigated or resolved?

Below is the relevant sample code (the operation in the red box has been modified to configure the PMIC WDG address, which has been verified to work effectively).

Thank you for your assistance!
