web server questions on DK-TM4C129X

Hi, in the weather demo shipped in DK-TM4C129X, does it run a XML parser? If yes, how to access to the function? If not, do you know how the XML parser can be implemented in TM4C129X? SSL is mentioned to be supported in TI-RTOS. How about other RTOS, such as FreeRTOS, without RTOS?

 

Thanks,

John

    Hi John,

    The weather demo has a simple Json parser. It doesn't parse XML. You should be able to implement the XML parser, but we don't have any example code for it.

    As for SSL,  we don't have SSL support in any of the demo code currently.

    Thanks Angela. What's TI's plan in supporting SSL on the Tiva C?

    Best,

    John

    I know we are interested in having SSL support on Tiva devices. However, due to some license issue, we haven't found a existing SSL stack that we could use which allows us to include it in our release. I am not a lawyer, so I don't pretend that I understand the license restriction. If we have any updates on the SSL support in the near future, I will let you know.

    Hi Angela ,John

    I'm also trying to run weather demo shipped in DK-TM4C129X and it's not running.

    Did you flashed any image or changed any Jumper settings for the application to run?

    We did the board setup as mentioned in Tiva DK-TM4C129X Getting Started Guide and connected ethernet cable.

    PreProgrammed quick start application is not running and there is no indication for Ethernet connection after connecting Lan cable.

    Display is also Blank(no contents show in display)

    I followed below instruction from Getting started guide and installed all necessary drivers in Windows 7 system

    Install Power Select jumper J11 (top left corner) to the In-Circuit Debug Interface (ICDI) for

    debug power select mode. Connect one of the included USB Micro-B plug to USB-A plug

    cables from a Windows-enabled PC to the ICDI Debug USB Port (top right corner) on the Tiva

    TM4C129X development kit. This USB port provides JTAG debug and Virtual COM Port

    connectivity via the ICDI.

     

    Can you help us to run the sample application

    Thanks,

    Mani

    Hi Mani,

    When you pluggin in the usb cable to the DK, does your windows machine recognize the device? In the device manager, there should be a device called "Stellaris In-Circuit Debug Interface", in that device, there should be "Stellaris ICDI DFU device" and "Stellaris ICDI JTAG/SWD Interface" listed under.  

    If it is recognized by Windows. You can use LM Flash Programmer to download any sample apps to the flash, such as blinky, this way you can verify that you can program the board, and verify that board is functional.

    Next you can program the weather demo to the dk,  there should be some debug message on UART output which might give some clue what is not working correctly.

    There is no jumper setting change required to run both apps(blinky and weather app). Whatever the default setting is good.
