Problem in using GPIO interrupt in DM6446

SB54399
Prodigy 120 points

Hi,

I am using CCs 3.3 with dsp/bios 5.31 in simulator mode for DM6446. I intend to simulate GPIO1interrupt  with DSP/BIOS in simulator mode. I have set up the registers as mentioned at http://processors.wiki.ti.com/index.php/Configuring_GPIO_Interrupts. IER is enabled in main () using C64_enableIER (C64_EINT5);

Pin muxing is done in the main() and the initialization of DIR, BINTEN, SET_RS_TRIG, in a task. Then using CLR_DATA and after it SET_DATA (in a while loop in the body of the task) i made a rising edge to simulate the hardware interrupt. But my hardware interrupt is never invoked.

I am using event 65 for GPIO1 as given in sprue25a for DSP interrupt in HWI_5. I have also enabled the dispatcher. As i am using DSP/BIOS so GIE is enabled by default.

Kindly help me out with it what could be the problem?
