TM4C1294 Connected Launchpad Workshop lwip files seem to be messed up

Charles Fleck

Hey guys,

I was recently using the TM4C1294 Connected Launchpad workshop files to program my Tiva C Series Connected Launchpad. I was using the enet_io and enet_weather examples and they were running fine. Today I was creating my own CCS project that used the same lwip files and it was not compiling well. I decided to take a step back and try using the enet examples again, but they had suddenly stopped working. The examples that do not use lwip, such as the blinky example, still compile and work fine, but enet_io, enet_weather, and my file all don't even compile. I tried reinstalling CCS and the TM4C1294 workshops, and I still am having the same problems. They both have been getting a bunch of errors in files like raw.c, sys_arch.c, sockets.c, sys.h, sys_arch.c and a few others. It appears that some things are not being properly defined anymore which is causing these errors. Do you have any advice on how to get these running again?

Thank you very much!

Charles

    Hello Charles,

    Did you clear the workspace for CCS?

    Might it be time to better, "Advise, Highlight or far more detail" the (apparently) "over-challenging" creation of user's OWN Project?

    Reports such as poster's occur so frequently - so predictably - does that not signal, "More detail and/or laundry list method" is required?

    No poster has (yet) explained his/her "great need" for "own project" - they pay a large price for such (never described/justified) "need!"

    Curiosity kills cats - and torments unsuspecting/unguided "create my own" users...  (perhaps rightly so...)

    Yes, I tried clearing the workspace. I also tried uninstalling CSS and the TM4C1294 workshop and reinstalling them, but I'm still having the same issues.


    Thanks!

    Hello Charles,

    I haven't seen an issue like after clearing the workspace (deleting it completely) and installing TivaWare.

    I think that the problem is solved now. I reinstalled CSS and TivaWare again, which got rid of the build error but caused a new error; this time regarding an output file missing. I added the output file and everything appears to be working again. I think the error may have occurred when I upgraded the compiler CSS was using, but I haven't actually tested that out.

    Thanks!

    Would not a (more correct) test involve your launch of (another) "own project?"

    You past described "that action" as the trigger of your issues...

    Oh when I said everything was working that included my own project. The only difference that I can see right now is which compiler I am using. Although it is also possible one of the lwip files somehow got muddled with by accident.

    Hello Charles,

    The CCS compiler must not cause a build error.
