CCS/IWR1443BOOST: Memory refresh in CCS of IWR1443 doesn't work

Hi,

I'm recording raw data of the IWR1443 with the CCS.

I see the memory but it won't refresh even though I'm pressing the refresh button.

So I can only save the first snapshot of the memory.

will be glad for some help.

Thanks,

Boaz

    Hi Boaz,

    The xwr1443 capture demo will only fill the L3 memory once.  To change this, you will have to modify the CaptureDemo_mainTask in main.c. This task starts at line 822.  There is an if statement at line 867 that triggers a DMA memory transfer of ADC data to the L3 buffer if true.

    After you have modified the Capture_Demo to continuously store chirps in the L3 buffer, you will need to make sure the chirp configuration you are using is set to infinite frames. To do this, change the 4th argument in frameCfg to 0.  

    Regards,
