Issues on LED Blinking using multiple GPIO on F28335

Hi, i'm trying to do LED blinking using GPIO 0 to GPIO11 on C2000 experimenter kits (F28335). I have connect the mentioned GPIO to my oscilloscope.

However, I only can get the pulsed waveform from GPIO2, 4, 6, 8, and 10, but the others have no waveform.

Is that my coding have problems?

Below is my setup code:
