TMS570LS0432: How to Enable GIO interrupt in Halcogen and use it in ide .

Tool/software:

Hi

I am working on the GIO interrupt where i have selected port GIOA and enabled interrupt on high priority . I have set the direction as the input of the gio bit 7 ,but i am unable to get the result i want .

Here is my code :

gioInit();

printf("Start\n");

vimInit();

gioSetDirection(gioPORTA,0<<7);

gioEnableNotification(gioPORTA,7);

_enable_IRQ();
