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!
