I Can use the Exec Graph tools, but when I run a program, the Exec Graph is not shown, As below

my program is the example in CCSv4.2 software .If I want to see the Graph, what configuration I need to change, or I didn't do some necessary steps ?
In addition, the console window displayed the following information.This information has been repeated display
TMS320C64X+: Warning: CPU:Interrupt No. 4 dropped, an earlier interrupt is pending to be taken
TMS320C64X+: Warning: CPU:Interrupt No. 4 dropped, an earlier interrupt is pending to be taken

TMS320C64X+: Warning: CPU:Interrupt No. 4 dropped, an earlier interrupt is pending to be taken
TMS320C64X+: Warning: CPU:Interrupt No. 4 dropped, an earlier interrupt is pending to be taken
