Hi, I searched the forum and there are several posts related to this problem, but no single method to answer the issue once and for all. It happens randomly when I change the source code of examples I am working on. The error itself is random too, with the memory address changing and sometimes not even shown.
My environment is the following:
CCS for Mac OS version 6.1.1.00028
Launchpad TM4C123G with a Tiva TM4C123GH6PM
Digilent Orbit Boosterpack
Stellaris ICDI
Mac OS X 10.10.5 Yosemite
The error happens after I change the code, often when I remove code that I do not want to keep. When I debug and step into the code I can see one pointer change from this
pbFont unsigned char * 0x000031F3 "\275\255\361\010\015\001\221" (Hex) 0x200004EC
to this
pbFont unsigned char * 0x202020B0 (Hex) 0x200004EC
This is the GEL file
menuitem "StartUp"
hotmenu StartUp()
{
/* Load the CortexM3_util.gel file */
GEL_LoadGel("$(GEL_file_dir)/CortexM3_util.gel");
GEL_MapOff();

I can't see a way to solve this problem. I will be very grateful for any guidance and enlightenment I can be provided. I am very new to Code Composer and I admit to have a limited knowledge of it.
Regards,
Angelo
