RTOS/AM5728: PRU interrupt on DSP

Part Number: AM5728
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI-RTOS

I want to setup a zero latency interrupt on a DSP core in the AM5728 processor to handle an interrupt signal coming from a PRU.

I included <ti/sysbios/hal/Hwi.h>

When the source code is compiled, I get:

"PRU.c", line 51: warning: function "Hwi_plug" declared implicitly
"PRU.c", line 61: warning: function "HWI_enableIER" declared implicitly

Are these even supported on this core?
