Looking for a working HTML demo - all attempts at TivaWare demos not working

Other Parts Discussed in Thread: EK-TM4C1294XL

(interim update) - I just now realized that there is specific setup and notes for makefsfile in 'SW-EK-TM4C1294XL-UG-2.1.3.156.pdf'. Most specifically I see that there are command line options there which I did not use (e.g. -h)! I will thus hold this question until I have finished going through this and trying it out too! :)

Problem

Is there any HTML server demos available within TivaWare, from TI or elsewhere? I have spent hours this morning attempting modification of the enet_fsdata.h in the TivaWare enet_lwip demo code, with the makefsfile utility and nothing is working.

Question

I could debug my current code to attempt towards success but instead I pause, take a deep breath and ask - has TI done this before, and provided a demo for you to use? :)

Goal

The ultimate goal is to get my hands into HTML serving of an index.html, hopefully streaming some type of content (e.g. data) ultimately.

    Hello Justin,

    Have you taken a look at the enet_io example under the EKTM4C129XL board examples? This is an example of the TM4C hosting a web server. It uses 2 different methods to provide the web pages (C:\ti\TivaWare_C_Series-2.1.3.156\examples\boards\ek-tm4c1294xl\enet_io).  Section 2.17 of the userguide SW-EK-TM4C129EXL-UG-2.1.3.156.pdf has a more detailed explanation of what it does.

    Also, I've attached a PDF of a section of a training where the enet_io was used as an exercise for the class. The slides walk through the project setup, import and some customization potential in a step by step manner. Note that these are old slides so some references are old (for example they mention CCS5.5 as the IDE).

    Well thank you Chuck, again for helping me solve my problems and come to conclusion!! :)!

    See the attached final_example_makefsfile.zip for clear and detailed illustration of how I solved this by working example. See the two other ZIPs for pre and post solution!

    Thank you Chuck!!

    Procedure (also found in final_example_makefsfile.zip/procedure.txt)

    1. Update the contents of /html to hold your webpage
       
    2. Make sure no copy of enet_fsdata.h is present in this directory

    3. Run demo.bat. A new enet_fsdata.h is generated from the contents of /html into this directory

    4. Take the generated enet_fs_data.h and paste it into the project, overwriting the pre-existing file

    5. Clean your CCS Project

    6. Build your CCS Project

    7. Open PuTTy, connect to Tiva

    8. Launch CCS Debug session on your project. Wait until "Open a browser and enter the IP address." appears in PuTTy

    9. Open a web browser and navigate to the IP Address delivered in PuTTy (e.g. 192.168.1.55/ for my test)

    10. Validate you see the page, that the sub pages work, that the image works and that the video works

    Complete! :)
