RTOS/TMS320F28379D: Regarding SYS BIOS Hwi(Hardware Interrupt)

Tool/software: TI-RTOS

Dear Sir,

I am working on SYS/BIOS with F28379D. I took the Minimal project Example for SYS/BIOS. I have done Task, Swi, and semaphore successfully.

Now I want to try to insert a Hwi, the main CPU timer interrupt has done successfully but I am not able to make Hwi for other peripherals like PWM, ADC. 

I tried to make a Hwi, taking the simple example in driverlib named adc_ex2_soc_epwm. It is not invoking the interrupt function that I created in app.cfg interface. 

I also shared the app.cfg code and the main program code. 

Please guide me where I am going wrong.
