Hello,

On my board I am using SCC1 and SCC2 for 10 Mbps
ethernets.

I am also using SMC1 and SMC2 for some 9600 baud
serial connection.

I am also planning on using IDMA1 for some DMA. My
chip is a 860P are there any problems with Parameter
ram conflict?

All SCC1, SCC2, SMC1 and SMC2 work fine. But my IDMA1
CPM interrupt handler never gets invoked, on hardware
side I do see the DREQ line going low and I have
verified that RCCR register for CPM is set correctly
to level trigger the interrupt.

Any ideas on why IDMA1 interrupt handler is not
getting invoked?

ANY HELP !!!!

John
