I built a minimal ML510 system that includes PCI. The Linux kernel boots, but any PCI cards that I put in are unusable. The bus scan finds the card, but when the kernel tries to send or receive data from the cards, nothing gets through.
Is there a work-around?
Base System Builder incorrectly sets some parameters. The following changes to the MHS file will need to be made:
PARAMETER C_IPIFBAR2PCIBAR_0 = 0x0000000
PARAMETER C_IPIFBAR2PCIBAR_0 = 0x20000000
PARAMETER C_IPIF_SPACETYPE_0 = 1
Should be removed
PARAMETER C_PCIBAR2IPIFBAR_0 = 0x83e00000
PARAMETER C_PCIBAR2IPIFBAR_0 = 0x00000000
PARAMETER C_PCIBAR_LEN_0 = 16
PARAMETER C_PCIBAR_LEN_0 = 26
The following constraints will need to be added below the PCI Net assignments:
TIMESPEC TS_PCI_BUS = FROM fpga_0_PCI32_BRIDGE_PCI_CLK_FB_pin TO clk_125_0000MHzPLL0_ADJUST 8000 ps DATAPATHONLY;
TIMESPEC TS_BUS_PCI = FROM clk_125_0000MHzPLL0_ADJUST TO fpga_0_PCI32_BRIDGE_PCI_CLK_FB_pin 30000 ps DATAPATHONLY;
