AWR1243: Not able to connect with the TDA board

MMWCAS-DSP-EVM: Not able to connect with the TDA board from some moment...

hi, I have problem with connection with TDA board.  


The radar was working fine, but from some moment it started not working.


I checked every step in document 'mmwave_studio_cascade_user_guide' section 13 and exactly the same results are shown as in the previous post(13.a~ 13.e),'AWR1243: Not able to connect with the TDA board'.


WinSCP is not able to use, so I tried it with Teraterm and followed some instructions in section 10.4 to activate 'apps.out'. These are the steps I tried. As in the section 10.4, I tried following commands.

Once booted, enter the login username as “root”
- Navigate to /opt/vision_sdk folder using the below command
cd /opt/vision_sdk
-  In order to verify whether apps.out is running automatically or not, issue the command
ps | grep apps

 
These are the results. 
 
After that I tried the next command 

-Once it is confirmed that apps.out application is not running, provide the command in the 
console
./apps.out

However, something is wrong with the program and above outputs were printed out repeatedly. (Never stopped...) 

Is there any other command or instructions for this problem?

I also tried the instructions in section 6 to check if initial setting is not working. These are the results of following commands. 

Something wrong happened with the part I circled in blue lines. I attach result of them if it could help to solve the problem I am suffering.

Also, this picture shows the LED status of the RF board. I think we are having problem with LAN connection so please check if the LED status is fine.

I tried these steps with other labtops but It didn't work too. 


I would be very grateful if you could reply as soon as possible. 


Thank you.

    Hello User, 

    I understand your concern and would be happy to help. 

    So as a first step, you're basically not able to connect to the TDA board using mmWave Studio? Is that correct? 

    Can you let me know the status of each of the following point in the below image : 

    On the Apps.out, I can see that is already running in your case, when you issued the "ps | grep apps" command, so you weren't supposed to run that manually, but since you did issue ".apps/out" command manually, it might have messed up with some execution. 

    In case you want to run it manually now, you would need to edit the required scripts accordingly. Please follow Section 10.4 of the user guide closely for that. 

    Regards,

    Ishita

    Thank you for your answer. 

    "So as a first step, you're basically not able to connect to the TDA board using mmWave Studio? Is that correct? "

    yes, These are the output log from the mmwave studio 3.0.0.14 when we tried to connect capture card. (Actually it worked well just before few weeks.)

    [13:54:47] Not able to connect with the TDA board. Please check whether the Capture Card is connected to the network!

    We already tried all of the steps in below figure. The results of below guidelines are almost the same with the posing in this link: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/917791/awr1243-not-able-to-connect-with-the-tda-board

     

    13. Troubleshooting: Not able to connect TDA2XX from mmWaveStudio over the network
    a. Check the Ethernet cable connection, LED status on TDA2xx Ethernet port connection. Confirmed 
    b. Ensure the PC IP address to be the same as mentioned in the Section 7.3.1. confirmed
     Try to ping TDA2XX IP address from PC to verify if the network connection is proper.

    I tried it using Teraterm app. confirmed (It worked well but command never stopped...)

    c. Check the terminal screen if it had any error message while booting up.

    These are the errors I am getting by rebooting the board. while booting, such messages were shown up.

     If yes, then try to reboot. , I did but getting the same errors

     Flash the SD card again if the error persists., I did but getting the same error
    d. At the terminal screen, check if apps.out process is running with the command
    ‘ps | grep ‘apps.out’’
    apps.out is the application running on TDA2XX which establishes network connection with mmWaveStudio.
     Ideally this application should run automatically on boot up. If not, then run it manually. Refer Section 10.4 on how to run it manually.

    I tried to run manually in section 10.4 , but I couldn't connect to the board via WinSCP. 

    Also I tried it in Teraterm and the results are following (same with figure in previous question.)

    e. Restart the TDA2XX board if none of above solution works. I did, it didn't work

    Thank you.

    Hello Kyoung, 

    Thankyou for the detailed response. 

    You can try a couple of steps here : 

    1. Try changing the SD card.

    2. I don't see the command "ps | grep apps.out" in your recent screenshots. Did you try to run that manually again?

    In case you're not able to connect to WinSCP, you can do so on TeraTerm as well, as suggested by me in the previous thread. 

    Just make sure you do not see that when you send the command "ps | grep apps.out". After this, you can issue the command for the execution manually. 

    3. Also make sure that the MMWCAS-RF-EVM is tightly connected to MMWCAS-DSP-EVM. sometimes the connection gets loose and it can cause this. 

    Let us know your insights. 

    Regards,

    Ishita
