DCA1000EVM: No packets received from DCA1000EVM

Mohamed Safawi
Prodigy 110 points
Part Number: DCA1000EVM
Other Parts Discussed in Thread: AWR2944EVM, , AWR2944

Tool/software:

I have made a program that sends the LVDS.cfg to an AWR2944EVM radar and should return the streamed data from the dca100evm. however as i went through the troubleshooting guide in sec 8 of the DCA manual when checking for received packets on Wireshark I see that port 4096 works at sending commands however nothing is returned on port 4098. I am in the 011 SOP and the cf.json is set to lvdsmode 2 for 2 lane lvds data that the dca sw2.3 is set to.

    Hi,

    There is a tool to capture the ethernet packets. You can check "C:\ti\mmwave_studio_03_01_01_00\mmWaveStudio\ReferenceCode\DCA1000\Docs\TI_DCA1000EVM_CLI_Software_UserGuide.pdf" and "C:\ti\mmwave_studio_03_01_01_00\mmWaveStudio\ReferenceCode\DCA1000\Docs\TI_DCA1000EVM_CLI_Software_DeveloperGuide.pdf" documents.

    You can use DCA1000EVM_CLI_Control.exe present in C:\ti\mmwave_studio_03_01_01_00\mmWaveStudio\PostProc to record the data in a *.bin file.

    I am already using that. There appears to be a communication issue between the DCA1000EVM and AWR2944EVM. I can send the profile_LVDS.cfg to the radar and send CLI commands to the DCA but I dont receive anything back for the DCA. The LVDS Path Err light also turns on.

    Mohamed,

    The default destination Ethernet port address configured in the DCA1000 EVM is 192.168.33.30 and socket number is 4098. Ensure that target PC is set with this IP address to receive the raw ADC data from the DCA1000 EVM.

    Yes, these setting are already in place. However I did check the sockets in my pc and the 192.168.33.30 ip address is connected to these three sockets  50593
    50594
    2177

    should i change the cf.json to use two of these for the config and data port replacing 4096 and 4098?

    Here is a comprehensive list of everything I have done.

    1. sent profile_LVDS.cfg over xds1100 UART port and read this on the xds data port 

    2. Put radar SOP to 011

    3. flashed radar with awr2944_mmwave_TDM.appimage

    4. DCA SW 2.5 to Sw_CONFIG

    5. cf.json is set to LVDS capture, Enet stream, 1243 mode, RAW mode

    6. all ./DCA_CLIControl.exe commands are successful (FPGA, sys_status) except once start is sent in error before stop can be sent

    7. XDS, FTDI, FPGA, 60 pin ribbon cable, and Ethernet cables are plugged in

    8. IP Address confirmed to be correct.

    The issue is that I dont receive any packets form the dca.

    Hi Mohamed,

    Put radar SOP to 011

    Set the EVM in QSPI Boot mode to run the SDK demo.

    Also ensure number of frames set using frameCfg CLI command is 0 (infinite frames).
