interrupt handler for microblaze system

[Frank]

Hi,

We have made our own opb slave which has an interrupt signal to the opb
interrupt controller. In the mpd file you have to specify this signal with
the options "level" or "edge" and "sigis=interrupt". In that way you can
connect the signal to the interrupt controller. But when assigning an
interrupt handler for this handler I get the error:

ERROR:MDT - monitor.mss:70 - Property interrupt_handler is not found
Software System not created ..
make: *** [mblaze/lib/libxil.a] Error 2

I have in the mss file the following:

BEGIN DRIVER
PARAMETER HW_INSTANCE = opb_my_device
PARAMETER DRIVER_NAME = generic
PARAMETER INT_HANDLER = my_opb_device_handler, INT_PORT = Intr
END

What do I forget?

TIA,
Frank
