Ethernet Driver problem?

[inxen]

Hi,
I'm trying to load linux kernel in an Avnet LX9 microboard. I'm working with xilinx-14.1-build version and using the Xilinx AXI Ethernet Driver, but when I run linux and type the command: 'ifconfig eth0 up'
I receive: ifconfig: SIOCGIFFLAGS: No such device

Is posible that does not exist a valid Ethernet driver for this board?

What I may do?
Thanks

No experience with this platform. Some generic things to try. What does just "ifconfig -a" display? You could try the "ifup" and "ifdown" command scripts. Depends on how your file system is arranged.

The Ethernet driver isn't board specific, so it should work fine with the AXI Ethernet core on the Spartan-6 LX9 microboard. Do you have the Ethernet core in your DTS file, and did you fully build support for the AXI Ethernet driver into the kernel?

Hi, I've tried these commands, and their replies are :

'ifconfig -a'

lo Link encap:Local Loopback
LOOPBACK MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

'ifup eth0'

ifup: can't open '/etc/network/interfaces': No such file or directory

And this is the code section of my DTS and .config files:

DTS:

axi4lite_0: axi@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "xlnx,axi-interconnect-1.03.a", "simple-bus";
ranges ;

device_type = "network";
interrupt-parent = <&microblaze_0_intc>;
interrupts = < 1 0 >;
local-mac-address = [ 00 0a 35 1e bc 00 ];

mdio {
#address-cells = <1>;
#size-cells = <0>;
phy0: phy@7 {
compatible = "marvell,88e1111";
device_type = "ethernet-phy";
reg = <7>;
} ;
} ;
} ;

I have added the Ethernet core in DTS file and Ethernet AXI driver in .config file.

I'm working with ramdisk (root=/dev/ram), it could be the problem?

Thanks

[norman_wong]

Sounds like the driver is in place. But the only the local loopback is being configured. The DTS file, "chosen" section, the "bootargs" should have an "ip" argument like:

ip=:::::eth0:dhcp

Assumes you have a DHCP server on your network. Static ip definition is a more complicated. You might want to add "earlyprintk" as well. Just in case nothing prints out during boot. The ramdisk shouldn't be a problem. Ramdisks appears to be the Xilinx way. Anything in the boot messages that mention the network driver?

Thanks for reply norman.
In other forum, suggested me to use an older kernel version. Now I'm usign xilinx_v2.6.37.
With this version after run linux and type command 'ifconfig -a' I get this response:

eth0 Link encap:Ethernet HWaddr 00:0A:35:A1:E8:00
BROADCAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

I can see eth0 interface, but when I try 'ifconfig eth0 up' command appeared this new error:

net eth0: of_phy_connect() failed

As you say, I put this argument on boot: 'console=ttyUL0 root=/dev/ram ip=:::::eth0:dhcp'
and during the boot messages appears this error:

Fixed MDIO Bus: probed

Xilinx Emaclite MDIO: probed

Any suggestion?

Thanks

The simplistic response would be to say thay the PHY ID on your board is not 7. This ID is probably hard wired by pins on the 88e1111.  Unfortunately my ignorance of the board might lead you astray. You could try to figure out how the 88e1111 is ID pins are strapped down and change the DTS file to match. Sorry that's all I got. Maybe "ra" will have a more informed response.

I know there has been long time from last post , but is there some one have been solved this problem?

when i want to assign

net eth0: of_phy_connect() failed                                                
ifconfig: SIOCSIFFLAGS: No such device

[cone83]

I'm also interested in a solution. I'm facing the same problem (probably).

Hi,

This problem says you are using the wrong PHY or PHY address. You should check your device tree to make sure your have correct PHY. An example as following,

axi_ethernet_eth_buf: ethernet@40c00000 {
axistream-connected = <&axi_dma_1>;
axistream-control-connected = <&axi_dma_1>;
clock-frequency = <100000000>;
clocks = <&clk_bus_0>;
compatible = "xlnx,axi-ethernet-1.00.a";
device_type = "network";
interrupt-parent = <&microblaze_1_axi_intc>;
interrupts = <4 2>;
reg = <0x40c00000 0x40000>;
xlnx,phy-type = <0x4>;
xlnx,phyaddr = <0x1>;
xlnx,rxcsum = <0x0>;
xlnx,rxmem = <0x8000>;
xlnx,txcsum = <0x0>;
phy-handle = <&phy0>;
mdio {
#address-cells = <1>;
#size-cells = <0>;
phy0: phy@7 {
device_type = "ethernet-phy";
reg = <7>;
};
};
};

Hi ,

just verify whether this  CONFIG_XILINX_PHY  macro is enabled or not.
