DM3730 Interrupt Controller Register Access

Other Parts Discussed in Thread: DM3730, SYSCONFIG

Hi,

Thank You for reading the post and your time.

We are implementing power management on our DM3730 based product.

We had observed that while entering into suspend and the ARM interrupts are masked. While resuming the masked interrupts are unmasked.

While unmasking the interrupts when we access interrupt controller registers the system doesn't respond and seems to be hanging there.

Can you please let us know what all clocks/powers need to be enabled to DM3730 to access interrupt controller registers.

Regards,

Hi,

You can find very useful information about interrupt controller management in the Technical reference manual - chapter: 12.5 Interrupt Controller Basic Programming Model at the link below:

Hello BR,

After referring that section I have added the below code

g_intcpsRegs->INTCPS_SYSCONFIG = 0x0;
g_intcpsRegs->INTCPS_IDLE |= 0x1;

Even accessing the SYSCONFIG and IDLE registers is also not allowed.

Please let us know if I need to check any power source or clocks?

Regards,

GSR
