CCS/MMWCAS-RF-EVM: AWR1243P cascade system imaging radar

MMWCAS-RF-EVM: MMWCAS-DSP-EVM, AWR1243

Part Number: MMWCAS-RF-EVM

Hello,

We are working on cascaded version of mmwave radar. I have the same issue as the following thread: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/962429/ccs-mmwcas-rf-evm-awr1243p-cascade-system-imaging-radar . The reply doesn't help.

Initially I flashed the sdimage from TDA2x firmware as mentioned in mmwave_studio_cascade_user_guide.pdf. I was able to connect to the mmwave studio (in the sense, I was able to set up TDAxx capture card). Then I formatted the SD card and put the MLO file and Appimage as mentioned in VisionSDK_UserGuide_TDA2xx.pdf. Then I wasn't able to connect to mmwave studio. 

The ethernet LED glows. ipconfig recognizes the board. But data doesn't seem to be transferred just as the error says.

Error using icinterface/fopen (line 83)
Unsuccessful open: Connection timed out: connect

Error in radar_cascade_demo>openConnection (line 990)
fopen(tcpCmdSock);

Error in radar_cascade_demo (line 393)
openConnection(tgt_ip_addr, host_ip_addr,tcp_port_num, udp_port_num);

Please respond at your earliest convenience. 

Regards,

Aparna

    I realise that when I use teraterm (connecting to it serially using usb), I see under current system settings that my ip is 10.42.1.180 and that's why I had that issue mentioned above. How to change that ip address?

    Hi Aparna,

    If you are referring to the IP address of the cascade radar board, the IP address is assigned by DHCP server by default.

    If you want to change that, you should configure your DHCP server to assign the IP address you want.

    I understand all that. Now I'm in the stage of running the appimage and MLO file for the radar use case. In this stage I don't know how to change the IP address. Should I change the static ip of my pc when I actually compiled and built the appimage?

    Regards

    If you want to use static IP on the cascade device, you have to change the configuration before you build the image.

    To enable static IP, you have to set "enableStaticIpEth0" to 1 and set the static IP address in the below file.
