AWR2243BOOST: Easiest way to capture the LVDS data in bin files

Part Number: AWR2243BOOST
Other Parts Discussed in Thread: DCA1000EVM

Hi Experts,

May we ask what is the easiest way to capture the LVDS data in bin files (in fact the data sent on LVDS lanes and not the output of DCA)?
I hope you can help us. Thank you.

Kind regards,

Gerald

    Hi Gerald,

    Easiest way to capture ADC data from AWR device with the existing HW solution is to use DCA1000EVM, where all the ADC data can be stored to a binary file.

    As ADC data is streamed over LVDS lane so you need to have some host processor to capture this data. DCA1000EVM is one of the HW or else you need to have your custom Host processor to capture that data.

    On the other side if you want to capture single chirp data in terms of ADC data then you can take memory dump from CCS but it will be limited for one chirp ADC data.

    Hi Jitendra,

    Please be informed that customer think the initial request was to capture the data transmitted on the LVDS lanes, whis is in fact the data transmitted from AWRboost to the DCA1000 on LVDS lanes. Customer want it to be per lane.
    The binary file which DCA1000 is providing to the host PC is supposedly the processed data which includes all the lanes raw data. They already have this.
    Anyway, they are interested on the exact LVDS data which might have control information (sync data, etc) in additon to the outputs of the ADCs.

    Kind regards,

    Gerald

    Hi Gerald,

    In that case customer can captured the line signal using Logic analyzer and using some other analyzer tool to get these level of information. We don't have any HW tool available for this usecase.
