Part Number: AWR1642

Tool/software: TI C/C++ Compiler

when I set the advframecfg like that :

Each  advFrame should have 512 chirps in two profile , but when it runs , only profile0 was executed and got 256 chirps. What cause it?

    Hello Anist,
    In the above configuration I see that in both the sub frames the profileIndex used is same (0) , so for both the subframes the same profile would be used. If you are defining two different profiles then those indexes need to used in the subframe configurations.

    Hi Vivek
    If I set subFrameCfg[0].forceProfileIdx = 0 subFrameCfg[1].forceProfileIdx = 1 , each profile has 256 chirps , so every advFrame should have 512 chirps . But now , I can only get 256 chirps in every advFrame whatever both the sub frames the profileIndex used is same or not.

    Hi Anist,
    For this configuration could you please confirm chirp and frame-start interrupt counts (here frame interrupt count is equaivalent to sub-frame interrupt count). It should match with the numbers which is configured (frame_start = 2, chirp=2*256).
