MMWCAS-DSP-EVM: Triggering Capture and Configure Radar Through Linux

Hello,

I am trying to interface with MMWCAS-DSP-EVM and MMWCAS-RF-EVM (with AWR2243) through a 64bit Linux machine. I just need the ability to trigger the radar to start recording data into the onboard SSD. I have read through these following posts:

P1: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/944696/awr2243boost-streaming-data-over-usb-to-linux-ubuntu/3489674#3489674

P2: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1084944/mmwcas-dsp-evm-streaming-data-on-mmwcas-dsp-evm-in-an-embedded-linux-environment

P3: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/873544/tidep-01012-config-data-capture-without-mmwave-studio

P4: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1080646/mmwcas-rf-evm-mmwcas-rf-evm-are-the-any-documents-about-communication-protocol-between-mmwave-studio-and-mmwcas-dsp-evm

Please correct me if I'm wrong, but my takeaway from these posts are that

1. It seems possible to work on Linux without mmWave studio with DCA1000EVM (P1). Could the reference code for DCA1000EVM also work for MMWCAS-DSP-EVM? I have attempted this but I am struggling to connect to DSP-EVM while I am able to ssh into the DSP-EVM.

2. There's no documentation is available for the comm protocol between mmwave studio and MMWCAS-DSP-EVM (P4). According to P3, the mmwave_studio_03_00_00_14\mmWaveStudio\ReferenceCode\EthernetLib is the backend API between mmwave studio and DSP-EVM. Is it possible to provide some reference code or design guide like those in mmwave_studio_03_00_00_14\mmWaveStudio\ReferenceCode\DCA1000.

Also, are there potentially easier ways of doing this?

Thank you!

Hi,

Unfortunately this use case is not supported. There is no additional information.

Thank you

Hi Cesar,

I understand this is not officially supported and documented. I still have some questions:

1. If this is under-the-hood how mmWaveStudio talk to the board, is it possible to disclose what are the necessary steps to talk to the board?

2. Is PROCESSOR-SDK-TDAX and PROCESSOR-SDK-VISION still supported? They seems to have linux capability but there's no documentation on their respective website other than the whitepaper.

3. If the SDK is still supported, what is the TDA2x model on the MMWCAS-RF-EVM? I can't find the exact model other than one reference of TDA2Sx on Page 38 of RF-EVM's user guide.

Thank you!

Hi,

Unfortunately the Radar Processor SDK demo is no longer supported. However you should still be able to run it on your platform. Please see Item #13 in the below FAQ

(33) [FAQ] MMWCAS-RF-EVM: Cascade Board related Queries - Sensors forum - Sensors - TI E2E support forums

You are correct, this demo uses linux. The main difference is that this demo does not use mmwave Studio for configuration.

mmWave Studio is not supported on linux

thank you

Hi Cesar,

Thank you for the reference. I ended up using a Virtual Machine to work with the radar.

Best

On related note: I ran into the "Unable to load DLL 'RadarLinkDLL.dll'" error, and connecting the MMWCAS-RF-EVM did not help installing the driver.

I followed the advice from this post on installing Visual C++ Redistributable packages (x86) 2015. I feel that this particular fix to this problem is not visible enough so I'm linking it here again.
