Hi Steve,

I think the booting message tell me that the interrupt line is connect
OK,isn't it ?
> [    1.151038] eth0: Xilinx 10/100 EMAC at 0x40C00000 mapped to
0xD0020000, irq=2


and if you can tell me what should be care about in  hard design and in
kernel config with net?

HI Steve:

when i design the system ,i chose opb_emac_1.04a ,No DMA, Use interrupt ?
Is it the correct setting for the current driver?

Thanks

HI Steve:

when i design the system ,i chose opb_emac_1.04a ,No DMA, Use interrupt ?
Is it the correct setting for the current driver?

Thanks

Hi,
I use ml403 board and Edk 9.1 and kernel linux-2.6-xlnx 2.6.24rc8.
My emac runs normally with this kernel 2.6.24rc8.
My emac is dysigned on my bsp project with interruption and reset :
.MHS :
BEGIN opb_ethernet
 PARAMETER INSTANCE = Ethernet_MAC
 PARAMETER HW_VER = 1.04.a
 PARAMETER C_DMA_PRESENT = 1
 PARAMETER C_IPIF_RDFIFO_DEPTH = 32768
 PARAMETER C_IPIF_WRFIFO_DEPTH = 32768
 PARAMETER C_OPB_CLK_PERIOD_PS = 10000
 PARAMETER C_BASEADDR = 0x40c00000
 PARAMETER C_HIGHADDR = 0x40c0ffff
 BUS_INTERFACE SOPB = opb
 PORT IP2INTC_Irpt = Ethernet_MAC_IP2INTC_Irpt
 PORT PHY_tx_data = fpga_0_Ethernet_MAC_PHY_tx_data
 PORT PHY_tx_en = fpga_0_Ethernet_MAC_PHY_tx_en
 PORT PHY_tx_clk = fpga_0_Ethernet_MAC_PHY_tx_clk
 PORT PHY_tx_er = fpga_0_Ethernet_MAC_PHY_tx_er
 PORT PHY_rx_er = fpga_0_Ethernet_MAC_PHY_rx_er
 PORT PHY_rx_clk = fpga_0_Ethernet_MAC_PHY_rx_clk
 PORT PHY_dv = fpga_0_Ethernet_MAC_PHY_dv
 PORT PHY_rx_data = fpga_0_Ethernet_MAC_PHY_rx_data
 PORT PHY_Mii_clk = fpga_0_Ethernet_MAC_PHY_Mii_clk
 PORT PHY_Mii_data = fpga_0_Ethernet_MAC_PHY_Mii_data
 PORT PHY_rst_n = fpga_0_Ethernet_MAC_PHY_rst_n
END

Be carreful the reset pin is mandatory, at first i have ommitedd this IO ans
my emac didn't work.
I have just add this reset IO and emac works properly...
I dont know if the tall of tje fifo are important but i have always done
32768.

I hope i can help you...
