Problem in configuration of Tiva TM4C1294NCPDT on Code Composer Studio
I realized what I've to do. I need root privilege,so I have to update the .desktop file of code composer.

$ nano 'Code Composer Studio 9.2.0.desktop'


I edited the file to be :

[Desktop Entry]
Type=Application
Version=0.9.4
Name=Code Composer Studio 9.2.0
Comment=Launches CCStudio
Icon=/home/abdo/ti/ccs920/ccs/doc/ccs.ico
Exec=sudo /home/abdo/ti/ccs920/ccs/eclipse/ccstudio
Terminal=true
Path=/home/abdo/ti/ccs920/ccs/eclipse


then, it works properly.
