Subject: [U-Boot-Users] a problem about PCI initialization
Date: Wed, 3 Oct 2007 23:06:11 +0800 [thread overview]
Message-ID: <200710032306005002310@gmail.com> (raw)
Hi
I am debugging a board based on Sandpoint8245.
sandpoint8245.h has these defination:
(
#define PCI_ENET0_IOADDR 0x80000000
#define PCI_ENET0_MEMADDR 0x80000000
#define PCI_ENET1_IOADDR 0x81000000
#define PCI_ENET1_MEMADDR 0x81000000
#define PCI_ENET2_IOADDR 0x00000000
#define PCI_ENET2_MEMADDR 0x82000000
)
sandpoint.c has this defination:
static struct pci_config_table pci_sandpoint_config_table[] = {
{ PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, 0x0f, PCI_ANY_ID,
pci_cfgfunc_config_device, { PCI_ENET0_IOADDR,
PCI_ENET0_MEMADDR,
PCI_COMMAND_MEMORY | PCI_COMMAND_MASTER }},
{ PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, 0x10, PCI_ANY_ID,
pci_cfgfunc_config_device, { PCI_ENET1_IOADDR,
PCI_ENET1_MEMADDR,
PCI_COMMAND_MEMORY | PCI_COMMAND_MASTER }},
{ PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, 0x18, PCI_ANY_ID,
pci_cfgfunc_config_device, { PCI_ENET2_IOADDR,
PCI_ENET2_MEMADDR,
PCI_COMMAND_MEMORY | PCI_COMMAND_MASTER }},
{ }
};
After calling pci_init() I output a value to address 0x80000000 and then CPU goes wront. I am so confused.
If any of you can give me some hint, I will appreciate that very much!
Best Wishes
Jinlu
