I have downloaded CCS5.1.0.090000_linux.tar.gz and extracted the files but when I try to run ccs_setup_5.1.0.090000.bin using the steps in http://processors.wiki.ti.com/index.php/GSG:CCSv5_installation I get "command not found." I have done the chmod 777 but both ccs_setup_5.1.0.090000.bin on ubuntu 11.10 with and without sudo causes "command not found." What step am I missing?
