Hi,


I am developing a application on DSP side to communication over PCI bu
between my HOST PC(Windows XP) and DM648 EVM.

I use the following peace of code to generate the interrupt to host fro
DSP.

status = readConfigData(pciHandle, PAL_SYSPCI_STATUS_SET,
&interruptStatus);

interruptStatus = interruptStatus | 0x08000000;

/* Set bit in status set register */
status = writeConfigData(pciHandle, PAL_SYSPCI_STATUS_SET,
interruptStatus);

/* Set bit in DSP to Host interrupt register */
status = writeConfigData(pciHandle, PAL_SYSPCI_HOST_INT_ENABLE_SET,
0x08000000);

Now after execution of this code i get interrupt on host side as well a
DSP side.

Is anyone know about this?

Thanking you in anticipation,
Vijay Patel
