How to connect DM6467 PCI(master) bus

Hi,

I need to use a DM6467 board to control the other 4 DM6467 boards through PCI bus.

But I don't know how to connect the PCI master and PCI slave, such as PCI_clk and int_a.

    You can have a look at an older PCI UG like http://www.ti.com/lit/ug/spru581c/spru581c.pdf that has a section (8.3) on DSP as system host. Note that 6467 can configure itself via the back-end registers and does not need to configure itself over the bus the way early devices did.

     You should also look at the PCI-SIG spec to be sure they are proving all of the required central resources: clock, command bus pull-ups, arbitration, IDSEL generation, etc.

      There’s an appnote on how to use standalone arbiters in multi-master setups: http://www.ti.com/lit/an/sprab28/sprab28.pdf

      Incoming interrupts will need to be connected to a GPIO or similar pin on the host 6467 that can cause an interrupt on the ARM.
