Trouble with 24ep512gu814 counter in main

[anboli]

hello all,

Am working with 24ep512gu814, now am having trouble in increasing a variable count inside the program. All other ports & registers are being manipulated but not any variables manually declared/initialized.
the code is posted below

	#include <24ep512gu814.h>
	#include "REGISTERS.h"
	#include "PORT_BIT.h"
	
	#use delay(clock=25M)[CODE]

please help thanks in advance

Maybe delay is not proper, it might be too fast. Increase delay 10 times and see.

Maybe delay is not proper, it might be too fast. Increase delay 10 times and see.

the delay has nothing to do with the program. moreover the delay is working fine am getting a blink every one sec.

void main()
	{
	
		cpu_initiallisation();
	//	Init_timer3_32();
		count = 0;
		while(1)
		{	while(count!=10)
			{
				count=count+1;		//this is what is not counting
				rj1=~rj1;			//some port blink to indicate loop working	
                                portd=count;              //the portd value is never increased come what may!!
				delay_ms(1000);
			}
			count=0;
                        portd=0;
		}
	}
