    global variable not updating on F28335 in CCS5.1.0.09

    hello,

    I looked through the threads about this but could not find one that pertained to
    my problem.

    I am using CCS ver5.1.0.09. I’ve done this in CCS ver 3 without any problems.

    I am creating a global variable above main() as int volatile g_query_user_flag.
    In the header file: F28335_example.h, I have extern int volatile

    g_query_user_flag so it’s visible to other .c files.

    In main, I can change the value of g_query_user_flag without any problems. I
    cannot change the value of g_query_user_flag in other files that want to update
    it.  While in some other file that wants
    to update the  g_query_user_flag and
    cannot, I can force the update by hovering over it until the pop-up window
    shows up and just type the new value in. 
    I wonder if there is some sort of permission  issue going on.

    Do I need to change something in the Compiler setting as another member mentioned?

    Thanks

    Monika

      Monika,

      Does your code behave correctly?  For example, if you pass this variable as an argument to printf, does it print the correct value to the console?  I want to better understand if this is just an emulation issue in CCS 5.1, or if the application is actually failing.
