AWR2243BOOST: Transmitter connection issue in mmwaveconfig.txt of AWR2243 with DCA1000

Carlo

Part Number: AWR2243BOOST
Other Parts Discussed in Thread: AWR2243

Hello E2E,

Please help our customer with the mmwave configuration, see the full details of the query below:

I'm working with the TI AWR2243Boost and the DCA1000 for capturing the raw data using the mmwaveconfig.txt configurations. I'm able to doing some measurements by using 1TX and 4TX. I wanted to measure with 2TX and here's my problem. I'm changing the mmwaveconfig.txt accordingly to use 2TX but cannot set the boards up to use two transmitters.

My mmwaveconfig.txt:

Chirp Configuration success for deviceMap 1

Obviously it is possible to read the two chirp configurations with TX0 = 1 and TX1 = 2 but it's not possible to set the second TX1 = 2 configuration under the "txEnable[]" statement.

I visited a huge number of forums and unfortunately cannot find any solution to my problem. I attached also a picture of my hardware. I hope you can help me to fix the issue

Hi,

Do you want to enable 2TX at the same time or 2TX in MIMO fashion?

Thank you

Cesar

Hello Cesar,

Our customer would like to enable 2TX MIMO mode to obtain with the 4RX a higher angular resolution resulting in 8 virtual antennas.

Carlo

Hello Cesar,

The customer has another update as follows: Meanwhile, I tried to understand why it doesn't work. I think that maybe my mmw_config or mmw_example is somehow wrong and prevents the 2TX MIMO configuration somehow, but I'm not sure. Maybe you can share it with the experts, that they have a look at that if this helps.

PS: I got these files from openradarinitiative which provided the Linux solution for the awr2243 with dca1000. And everything is working as expected only this 2TX MIMO mode is not working.

Carlo

Hi,

Please review this example which uses 2 Tx

C:\ti\mmwave_dfp_02_02_02_01\ti\example\mmWaveLink_SingleChip_Example

Our support team can provide support for this example.

For the examples provided on openradarinitiative please work with the openradarinitiative community for supporting the examples

thank you
