MPC8360_INITIALIZATION issue

[rana_kspl]

Hi

I have used MPC8360 in a design.

However I am having issue in Initializing the processor using Code Warrior.

I have tried all RSW  modes from 000-111.

There is a hardware fallacy that has been found.The PCI_MODE pin of the processor is  accidentaly not connected .According to Datasheet it must be connected to either VCC thru Pull up or pulled Down.

Just want to know clearly if not Connecting PCI_MODE pin can stop the processor from initializing.

I have attched the debugger Log for reference.It seems that Processor is failing during Read Operation.

Please provide some Pointers ASAP.

PCI_MODE determines which pins the chip uses for its clock source.

In "PCI Host Mode" the CLKIN pin is the master clock. In "PCI Agent Mode" the PCI_CLK/PCI_SYNC_IN pin is the master clock.

If you don't have PCI_MODE connected then the chip doesn't know which clock to use. Yes, not connecting it would explain why it won't initialise.
