Subject: Using IDMA1 ( or IDMA2 ) on 860
Date: Sun, 19 Aug 2001 12:06:24 -0700 (PDT) [thread overview]
Message-ID: <20010819190624.51260.qmail@web20105.mail.yahoo.com> (raw)
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
