CC3200-LAUNCHXL: Websocket_simple example not working

Part Number: CC3200-LAUNCHXL
Other Parts Discussed in Thread: CC3200, UNIFLASH, CC3200SDK

Hi,

I am using CC3200 LAUNCHXL board.I am using

SDK - 1.5.0

CCS - 10.4.0

Service pack - CC3x00ServicePack-1.0.1.15-2.14.0.0

Uniflash - uniflash_cc3xxx_setup_3.2.0.00123

I am trying httpserver example. If I flash the board with the existing httpserver.bin file inside C:\ti\CC3200SDK_1.5.0\cc3200-sdk\example\httpserver\ccs\Release along with the other html files, It it working.

But if I import the same httpserver project into CCS just rebuild it and flash that httpserver.bin file it is not working.

Why is it not working if I import the example given ?

Please Help !

Thanks

  • Hi,

    When you flash the pre-built application, I assume you are loading the entire UniFlash session (including user files like html pages) and flashing that to the device?
    When you swap for your build of the application, can you confirm that you are using the same session and just replacing the application binary?

    What happens when you run the re-built version? Can you show a screenshot of what appears on the serial terminal?

    Thanks,

    Ben M

  • Hi,

    Yes. I am just changing the path of the bin file. Rest all remains the same. When I run the re-built version I am getting the same prints as the pre-built version. Just that when I try opening the webpage it is not able to open.

  • What do you see when you try to open the webpage? Do you even get to see the internal ROM pages?

    Thanks,
    Ben M

  • I am getting this

     

    or 

    when I try to open the webpage.

    I am attaching the tera term console print also,

    Regards,

    Vibhu.

  • Do you even get to see the internal ROM pages?

    How do I check that ?

  • Can you share a capture of the serial terminal window when it does work too?
    It looks like know servicepack version is being reported (mostly 0's). Was it showing up before?

    Best,

    Ben M

  • I am sharing the screenshot of the webpage along with the tera term prints using the pre-built bin file, Hope this helps.

    I am not flashing the service pack, I am just formatting the flash and flashing the webpage along with the pre-built bin file.

    Regards,

    Vibhu.

  • Hi Vibhu,

    Could you try removing this part from HTTPServerTask the source code before building?

    //Stop Internal HTTP Server
    lRetVal = sl_NetAppStop(SL_NET_APP_HTTP_SERVER_ID);
    if(lRetVal < 0)
    {
        ERR_PRINT(lRetVal);
        LOOP_FOREVER();
    }

    I'm not sure why the demo tries to force a stop then start of the HTTP server before entering the main while loop.

    You should definitely also load the servicepack to the device.

    Best Regards,

    Ben M

  • Hi Benjamin,

    If I try to flash the service pack, then the pre-built bin files and html pages It is giving some error. If I didn't flash the service pack file only then it is working properly with the pre-built files.

    This is the error I am getting when I use service pack and pre-built files,

     

    I will remove the part which you told, check it and will let you know in sometime.

    Thanks,

    Vibhu.

  • Could you try removing this part from HTTPServerTask the source code before building?

    Hi Benjamin,

    I tried commenting the block which you told. It it giving some error in Starting the HTTPServer,

    I am attaching the screenshot,

    Regards,

    Vibhu S.

  • Hi Vibhu,

    I tested this on my end and it works both with the pre-built binary and with rebuilding the example application from the SDK. It also works when load the latest servicepack to the device.

    One of the issues I see with your setup is that you say you are working with CCS 10.4. The CC3200 SDK v1.5 was developed to work with CCS 8.3 and the following TI ARM compiler. See snip here from the "Dependencies" section in the release notes:

    Please revert your change to the code snippet mentioned above and try with CCS v8.3. Older versions of CCS can be found here: 

    https://software-dl.ti.com/ccs/esd/documents/ccs_downloads.html

    Best Regards,

    Hi Benjamin,

    The link which you have shared is not opening. 

    It is just blank how many times I refresh.

    I tried with the CCS8

    But still it is not working with the re-built version and also it is giving the same error when I flash the service pack. I even tried the code changes which you suggested but still it is not working. 

  • Hmm. Interesting. It is working well for me.

    Did you change anything else in the code or in the UniFlash settings before building/flashing? Could you share a picture of your LaunchPad setup?

    The error you are seeing with the servicepack flashed seems to be a timeout in the driver when stopping the device. I would not expect that on the CC3200 where the integration of the driver to the hardware is well tested. Perhaps there is something else going on with the device settings that we are missing. You could try to capture the Network Processor logs from the device and share them for us to see what's going on. See chapter 19 in the NWP User Guide: www.ti.com/lit/swru368 

    It also looks like you have an older UniFlash for CC3x00 version (aka "UniFlash_Previous"). The latest should be v3.4. Please try using that version: https://www.ti.com/tool/UNIFLASH

    Best Regards,

    Ben M

  • Hi Benjamin,

    I did not change any settings in the uniflash. I even re-installed it and checked. And I forgot to mention that I have the latest version of Uniflash 

    Uniflash Version : 3.4.1.00012.

    The picture of the launchpad:

    I am attaching the logs which you have suggested me to take, I have logged both with service pack and without service pack. I am guessing the hardware is proper because someone else was using this board before. Since the pre-built example was working so I am guessing the hardware is ok.

    I was not able to attach the original file so I have renamed it as .txt

  • Hi Vibhu,

    Thank you for sharing the additional information and picture. I see that you are working with a Rev 3.2 launchpad and it looks like the CC3200 device populated on the board is a "Z" device (i.e. pre-production). I'm not certain, but my theory is that could be causing some issue in your test that I'm not seeing. I'm working with a Rev 4.1 board that has a "CC3200R1" on it. I'll see if I can find a pre-production board and run the same test.

    Also, the logs you shared appear to be very short. I can only see the beginning of the device start-up. Can you make sure the logging pin is muxed at the beginning of the application and ensure you were logging throughout the entire test run?

    Thank you,

    Ben M

  • Hi Vibhu,

    I confirmed that these boards with pre-production devices are not guaranteed to be compatible with the latest servicepack/SDK. The last SDK version that supported these was version 1.1.0 I believe.

    You will need to get a new LaunchPad to work with the latest software releases.

    Best Regards,

    Ben M

  • Thank you Benjamin. Sorry for the late response. I will try to get a new LaunchPad.
