Hello Champs,

Customer defined an array for sessionCfg.header, but after modifying the array in LVDSStream_HwTriggerFrameDone，the lvds signal doesn't output the new value. How to change the value in sessionCfg.header?

Below is some code. 


Thanks

    Hello Shine,

    The customer can go through the CBUFF code here C:\ti\mmwave_mcuplus_sdk_04_04_01_02\mcu_plus_sdk_awr294x_09_00_00_15\source\drivers\cbuff\v0\cbuff_transfer.c:

    This api is what sets up the header,  during the beginning and configures the EDMA for it as well
    Please advice the user to go through the same and try to modify.

    You cannot modify it like that as that has no impact on the hardware trigger session.
    The hardware trigger session is not dependent on the software, once the hardware trigger starts you cannot modify these headers as and when you want, that is why you have the software triggered session where you have the control.
