hi,
I have a system with MPC8240 as a arbiter. I have plugged a PMC card into the unused PCI slot. My system hangs up reporting fatal system error. My system (MPC 8240) uses a PCI based ethernet controller(DEC 21143).
When I stepped through emulator, I found that my DEC card gets interrupted reporting Master abort. I don't know what I am missing in my initialization. Can anyone point out what might be the problem??????? Without the PMC card, my system works fine.
What are all the possible causes of Master abort in a PCI transaction?.
bye
