IWR1843: Error in Self-Calibration with Fixed Rx Gain LUT

Part Number: IWR1843

Tool/software:

Hello,

When attempting to set an arbitrary Rx Gain LUT, an error occurs.
This is a continuation of the previous thread (https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1455999/iwr1843-error-at-self-calibration/).
I apologize for the delay in confirming and responding.


Fig. 1 shows the outline flow of the millimeter-wave control we tried in the previous thread.
Following the comments provided, I checked the data in the FLASH ROM.
After verifying the original data, the status of CAL Data, and the values of the LUT, I believe there are no issues with the data.
However, when setting MMWave_addProfile() with no LUT update, an error occurs in MMWave_config().
Therefore, referring to the thread (https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/733336/awr1642-mmwavelink-how-to-re-configure-profile-chirp-and-frame-setting),
when controlled as shown in Fig. 2, no error occurs, and it seems to use the intended LUT.

Is the control method in Fig. 2 correct?

    


Best Regards,
Yasuaki
