CCS: HPI Debugging

Tool/software: Code Composer Studio

I am interfacing DSP5416 HPI with my FPGA . I am trying to write to HPI register HPIC from FPGA using AXI EPC.

I have written simple hello world code in Code Composer Studio and in debug mode trying to view HPIC memory register to see whether what I am writing to HPIC register is reflected or not. I am not able to see any changes. Can u please tell me what is the problem. and one more thing whether watchdog timer should be disabled in DSP side Hello world code.

Hi Sridevi,

Could you share your Hello world code? Do try to debug step by step in CCS?

Hi Cvetolin

Here is my hello world code

#include <stdio.h>
// #include <csl.h>

/*
* hello.c
*/
int main(void) {
// printf("Hello World!\n");
int i =0 ;
/* Initialize CSL library, this step is required */
// CSL_init();

for(i=0; i <10; i++)
i++;
while(1)
{

}
return 0;
}

I have put while(1) loop. And in debug mode check the HPIC register. But there is no change in HPIC register.

Thanks and Regards

Sridevi,

I'm sorry for delayed replay.
You can enable/disable watchdog timer via WDEN Watchdog timer enable bit of Watchdog Timer Secondary Control Register (WDTSCR) as it is described in spru420d.pdf

I'm not sure why you not succeeding to change the HPIC register but I suggest you to add some delay in while(1) loop by TSK_sleep or adding some NOPs as it is described at:
