AWR2243BOOST: Strange behaviour by a small testPatGenTime

Part Number: AWR2243BOOST
Other Parts Discussed in Thread: AWR2243

We use a modofied OOB for AM273x and AWR2243. To identify that we interpret incoming data correctly we use rlDeviceSetTestPatternConfig .

Using testPatGenTime = 100, like in the examples, the data come as expected with the given offsets and increments. But if we set testPatGenTime to 28, data come in the wrong order, sometimes filled with zeros etc.

We interpret this value as the sampling frequency. So if we wanna mimic the 7.2 MHz sample rate we set 200/7.2 -> 28 cycles.   What is the meaning of this value and why do we get wrong values if it's set to 28?

Is it also correct, that the pattern will be sent once (if numTetsPtrnPkts is not 0), and not repeated like the frames usually do?

  • Hi Aleus,

    Apologies for a late response.

    Please find my below questions - 

    1) Can you elaborate what is the correct order and wrong order of data you are facing? Can attach any screenshot of the correct and wrong data?

    2) Have you checked with any other values of testPatGenTime? 

    3) Can you help me understand why exactly are you using value 28, is this a specific usecase? If yes, can you share some more details on the usecase?

    Regards,
