AWR1243: Boot and Run Time Calibrations

Hi Kyle, 

Thanks for the reply. My question was related to calibration not monitoring. In the ICD, there are enable/disable option for Tx Phase Calibration and RX IQMM Calibration. In the SPRACF4 document, 
these two calibration dont exist at boot time or run time.

Hi Anand, 

Thank you for the reply. I appreciate your help. 

The IQMM calibration is disabled in ES 3.0 I assume from your reply, but it is enabled in ES 2.0 based on our observations. Some chips on our board show IQ MM calibration passed and the other show failed. Is it better that we just disable the IQMM calibration then ?

Regards,

Hi all,

I have two related questions

1. With RX IQMM calibration (bit 12) disable as part of the calibEnMask for rlRfInitCalibConfig(), the async event message of RL_RF_AE_INITCALIBSTATUS_SB, still have RX IQMM calibration (bit 12) of calibStatus turned on. Does this mean the RX IQMM calibration is still running? Or does it mean the respond is incorrect?

2. Bit 11 for the calibEnMask variable inside the rlRfInitCalConf structure inside rl_sensor.h is defined as reserved (see below). However in the AWR1xxx Radar Interface Control Document Revision 0.95 – Dec 27, 2017. bit 11 is defined for Enable TX Phase calibration. Should it be set to 0 or do I have control over it?

typedef struct rlRfInitCalConf
{
/**
