AWR2944: Internal reference calibration recovery issue

Cherry Zhou

Part Number: AWR2944

Hi Team,

When restoring the radar antenna phase for internal calibration, the customer writes the corresponding 32 values through CLI's antennaCalibParams command and reads the customer's previously stored calibration phase antenna settlement values from flash and then populates the configuration by assigning values. And passed through dpm_iotal to DPM. What can be determined now is that the values passed to the dpc side are exactly the same, and what is strange is that the effects of the two are quite different, but the compensation values are the same for both methods: 

Could you help check this case? Thanks.

Best Regards

Cherry

    Hi Cherry,

    Can you provide more details on this?

    "reads the customer's previously stored calibration phase antenna settlement values from flash"

    What was the value stored on the flash that was retrieved? How was the calibration done for that? How does it differ from the Rx phase compensation config?

    Regards,
