MMWCAS-RF-EVM: Questions regarding using mmwave studio for MMWCAS-RF-EVM and MMWCAS-DSP-EVM boards

Part Number: MMWCAS-RF-EVM
Other Parts Discussed in Thread: MMWAVE-DFP, AWR1243

Hi, 

I read "mmWave Studio Cascade" user guide, but I need to understand the followings:

1. After running the radar system including the RF and DSP board, how the binary data are stored in TDA2xx? Are they like DCA1000 dumps storing binaries with the header and a payload containing the data length and the ADC data, respectively? 


2. Is it possible to use MMWAVE-DFP (the latest version) to configure the cascaded board using TDA2xx? Even though I know that this might need to configure some parameters for the individual chips, thus it needs to use the MMWAVE-DFP for each chip separately.


3. Before, we used to download MSS on to the chips for a single EVM board, but why do not we need MSS FW for the cascaded chips since there is no step to download them on the chips?

Best regards,

Mostafa

    Hi Mostafa,

    1)

    The data are raw binary files with data from each AWR1243 stored into a separate bin file. Some Matlab scripts are included that show how you can interpret the data.

    There are also timestamps stored in a separate file that allow you to look at the arrival time of each frame in the bin files.

    2)

    We do not currently support programmatically configuring the cascaded board using an example program in mmWave DFP. Currently, the only supported way is to use mmWave Studio and it's LUA API to configure the boards.

    It is also possible to configure the cascade board directly from the TDA2xx using the Processor SDK (http://www.ti.com/tool/PROCESSOR-SDK-TDAX). But please note that this may not be updated to use the latest firmware and code.

    3)

    Starting with AWR1243 ES3, the separate BSS and MSS firmware images were combined into a single metaimage that is downloaded to the devices. There is no separate MSS binary any more. This is not only for the cascaded chips, but for all AWR1243 ES3 devices.

    Best Regards,

    Anand

    Hi Anand, 

    About question 1, is the Matlab script to read the binary files in the mmawve studio package?

    Hi Mostafa,

    We include a Matlab package that reads and post processes the data directly. There isn't currently a simple version of this that only shows how to read the data, but you can start with the package that is included.

    Best Regards,
