[ixp1200] ENP-2611 board PCI-to-PCI bridge testing problem!

[smiley]

question ? ~~~!
Since I  still could not load the module, I changed hhnet_drawb.c.
---from----
#define DRAWB_CFG_SETUP_DS3       0xB8 
#define DRAWB_CFG_CHIP_CONTROL_1  0xCE
#define HHNET_DRAWB_MEM_SIZE      (1024 * 1024)
if (primary) 
{
 ...
 bar = 4;
 irq_handler   = hhnet_drawb_intr_primary;
}
---to----
#define DRAWB_CFG_SETUP_DS3       0xAC  
#define DRAWB_CFG_CHIP_CONTROL_1  0xCC
#define HHNET_DRAWB_MEM_SIZE      (4 * 1024)
if (primary) 
{ 
 ...
 bar = 0;
 irq_handler   = hhnet_drawb_intr_primary;
}
---
After the modification, I COULD load the module on both side, server, and ENP.
But still I could not make them to communicate.

The dmesg & PCI  info from the server side-----------------

The dmesg & PCI  info from the ENP side-----------------
<dmesg>
hhnet_drawb:  mem_paddr = 00000000
hhnet_drawb:  mem virt = cb687000

<pci>
  Bus  0, device   1, function  0:
    Bridge: PCI device 8086:b555 (Intel Corp.) (rev 2).
      IRQ 41.
      Non-prefetchable 32 bit memory at 0xe4000000 [0xe4000fff].
      I/O at 0x100000 [0x1000ff]

As you can see, the mem_paddr of ENP is set as 00000000. I think this is the reason of the problem.
I think the correct value is "0xe4000000". Am I correct?
If then, how do I fix it?

Thank you in advance.
