Hi,
My board is MPC8260 based board and I had been trying to initialize the
Tundra PowerSpan Registers.
Single PCI PowerSpan contains a lot of Registers like the
PCI-1 Register Image Base Address Register
PCI-1 Target Image X Base Address Registers
PCI-1 Target Image X Translation Address Registers
Processor Bus Slave Image X Translation Address Registers
Processor Bus Slave Image X Base Address Registers.
The PowerSpan manual does not give full details of what each corresponds to.
I am confused as to what address ranges to be entered for what.
I tried various sets of address ranges in which one looks like
PB_SI0_TADDR = 0x00000000; PB_SI0_BADDR =
0x40000000;
P1_BST0 = 0x00000000 size 32MB;
P1_BST1 = 0xFF000000 size 16MB; ...
When I try to access the PCI location 0x40000000 the system hangs.
If anyone has any idea on this, please help me out.
Thanks in advance,
Srini
