Sir,
i am using TMS320vc5502.My application is working properly in emulator mode.But in boot mode if
am writing a program without interrupt its working properly but if i am loading an a program
with interrupt its not working.I am using Serial EEPROM boot mode.U kindly tell me wts the
problem and reply me.

my code:
#include <stdio.h>
#include <csl.h>
#include <csl_gpio5502.h>
#include <csl_chip.h>
#include <csl_pllB.h>
#include <csl_irq.h>

extern Uint32 vecs;

After the program boots from Flash and just before this C code line in your program:

 if (TriggerFlag == 1) {

stop the code and check the IER bit and IRQ registers.  Are both GIE and NMI bits
set?  Are the correct IRQ bits set?  If not, then you have to debug why not.

You can use a breakpoint to stop the code.
