RTOS/EK-TM4C129EXL: Settings for the Ethernet/TCP/IP stack?

LouEEEE!
Expert 1955 points
Part Number: EK-TM4C129EXL


Tool/software: TI-RTOS

Perhaps the definitive noob question: Where are the parameters/settings in the Out-of-Box demo for the above-referenced board? 

Simply: Given issues we're seeing with this card using a DHCP-mediated connection, I'd like to hard-wire the IP interface for testing.

Yes, I know; I should scour the source code back to front...

    In the TI-RTOS XGCONF editor the IP address settings are under the IP - General Settings page:

    The default is that "Obtain IP address automatically" is ticked, which uses DHCP to obtain an IP address.

    If you un-tick the "Obtain IP address automatically" you can then enter a static IP address.

    Note that under CCS 7 if you double-click on a TI-RTOS .cfg configuration file, the file will be opened in the text editor by default. To open in the graphical editor right-click on the .cfg file in the CCS Project Explorer and select "Open with XGCONF" (you only have to do that the first time, the selection is remembered).

    Thanks, Chester, for your response.
    But, ( apologies, new to this entire ecosystem ) - what and where is this beast XGCONF of which you speak? ( a module I must - and am yet to - build? )
    My project - for the moment the Out-of-Box 'experience' for the EK-TM4C129EXL - has no such TI-RTOS.cfg file.
    ( Yes, have begin reading the TI-RTOS 2.16 User's Guide ... )

    My mention of the "TI-RTOS.cfg" was a bit vague; I meant the .cfg file in the project.

    The secure_iot project from the Out-of-Box 'experience' for the EK-TM4C129EXL has a secure_iot.cfg file. If you right-click on the secure_iot.cfg file in the CCS Project Explorer and select Open With -> XGCONF :

    That should ensure the secure_iot.cfg is opened by the XGCONF editor where as per my previous screen shot you can change the IP address configuration of the project to set a static IP address.

    Chester! Fantastic!

    Don't know if you guys permit obscenity on the forum, but I am tempted toward an enthusiastic expletive ! It just feels right...!

    Your simple explanation of 'Open With' has opened a floodgate of realization. I was fully onto the .cfg file - but in my simple-minded world, 'open' means: 'double-click'. As you can imagine, one never gets to XGCONF this way...

    I know, this stuff is obvious to users of CCS? Eclipse? I've used neither before in earnest. Have used loads of 'Build Systems' with 30-line config steps, but not Eclipse...

    Now, I get it: I should have known/guessed/surmised ... But this simple stuff really presents a barrier to entry.

    TI Sharpies/Higher-Ups? Take note: You have here a motivated system developer, already appreciative of the TI feature set and advantages, hoping to address a fairly large market - who has had a lot of trouble getting off the proverbial dime.

    Where are the self-paced, in-depth, well-written tutorials on this stuff. IE, a tutorial on interfacing an SPI device with the EK-TM4C129EXL?

    Chester, thanks for your feedback.

    The issue is that CCS has several editors associated with a .cfg file extension. In going from CCS 6 to 7 for some reason the default editor for the .cfg file extension was changed from "XGCONF" to "XDCscript Editor".

    In CCS under Window -> Preferences you can select XGCONF to be the default editor for a .cfg file:

    The default editor is used for a file, unless a specific editor has been previously selected for the file by right-clicking and selecting "Open With".
