AWR2243: Unexpected error code 315

Tegan Counts

Part Number: AWR2243

We're getting an error code 315. When we compute the limits offline using formulas in the ICD, we don't believe the error code should be thrown. Setup:

  • Advanced frame
  • Advanced chirp
  • Using dither LUT
  • 3 subframes
  • 5 bursts per subframe

What works:

  • num_loops_per_burst = [3072, 1536, 1536] (three subframes)
  • total_num_chirps = [15360, 7680, 7680] (three subframes)

What doesn’t:

  • num_loops_per_burst = [2304, 1152, 1152] (three subframes)
  • total_num_chirps = [11520, 5760, 5760] (three subframes)

I've attached a file detailing the sequence of subblocks that we call as well as the most relevant parameters sent in each subblock.

 As you can see, the setup that works actually has MORE total chirps than the setup that fails. TechMemo_9TDs.docx

    Hi,

    I request you to refer mmwavelink test application where we have given reference code for ADvChirp, ADvFrame and with dither LUT option.

    .

    Hope this will give you some clue to map your issue and resolve it.

    Let me know if you need further help.

    .

    Regards,
