Tool/software:
Hello,
Referring to the thread(Title: Question in regard to save LUT for Rx gain calibration in Self-Calibration, URL), we are implementing Self-Calibration.
Our understanding is as follows:
- At the factory, the RX gain LUT is read using the rlRxGainTempLutGet() function immediately after the MMWave_open() process is completed and saved to non-volatile memory.
When implementing the above, we observed the following:
- Upon checking the result of rlRxGainTempLutGet() immediately after executing MMWave_open(),
we found that the values in the rlRxGainTempLutData_t.rxGainTempLut array were all zeros, as shown below:
“0x0000000000000000000000000000000000000000” - Later, after executing MMWave_start() (i.e., after running the run time cal), we checked the result of rlRxGainTempLutGet() and found the rxGainTempLut as follows:
“0x2223232323030303030404040505050506060600”
The settings are as shown in Table 1 for MMWave_open().
Q1. As per the response in the thread, the LUT should save the results of RF_init() to non-volatile memory. So, should we save the LUT with all rxGainTempLut values set to zero?
If Q1 is incorrect, please advise on the following:
Q2.1 Is it a misconfiguration that causes rxGainTempLut to be all zeros? If so, please let us know which setting values are incorrect.
Q2.2 Should the LUT reading timing be after the runtime cal? In that case, is it acceptable to read the boot time cal results after the runtime cal?
Best Regards,
Yasuaki
