Hi,
I am a beginner, i am using DM6446 in our project, on its DSP c64x+, i want a interrupt from arm2dsp0, i.e on event-16 of dsp,
1. I have enabled all interrupts through IER register setting of 0X0000FFF0.
2. I have also set TSR to 0x00000001
3. i have set intmux1 register to 0x00000010, i am taking the arm2dsp0 interrupt on channel-4
4. i have also installed handler and set ISTP
BUT WHEN I FIRE INTERRUPT FROM ARM through INTGEN REGISTERBY SETTING ITS 4TH BIT TO 1, THE CODE DOES NOT GO INTO:
#pragma INTERRUPT(func)
interrupt void func(void)
{
}
do i also have to set EVTSET register?
why is it not going into interrupt function in dsp?
pls. help
