Sir,
Using PMC -PCI Adapter card ,i have interfaced my PowerPC MPC8280 (which is configured as PCI bridge) as agent to personal computer. when this setup having MPC8280 card with powered ON and connected to PC .PC is getting hanged while system is booting up. I am finding problem when this card is powered ON state before system is boot up. But if this MPC8280(PCI Bridge) card with powered ON is connected to PMC carrier adapter after PC has booted up, it is getting identified by system and able to watch my device details (configuration space) using "PCI Explorer Software". But using this software, it is showing this single PCI device as 31 different devices. Why this is showing as 31 PCI devices? Also why PC is not getting Booted, after this PCI Bridge in power ON state is connected to PMC -PCI Adapter card that already in PCI slot of my PC? I am unable to solve this problem. I am finding the same issue even I am using this set up on Linux based host . I approached Freescale support for this issue by sending my PCI card schematics. They analyzed and came up with small changes, but still we could not able to solve this problem. So we wanted to start tracing the problem from software side. That's why I wanted to install my PCI card into Linux based host. To do this whether I need to write /include any driver code into my Linux host .If I need to write driver code how to start & where exactly needs changes/inclusions of code stuff in linux code. Already I am studying kernel documentation and drivers code under source code. Referring Linux device Driver 3rd edition O'reilly s book. I am new to linux. Please help me in getting through this problem. Thanks & regards V mohan rao
