I am new to OpenRISC development. I'm attempting to install Linux into an Atlys board via u-boot. With u-boot into the Flash memory, however, I can't seem to retrieve the Linux image file from a tftp server. I can't ping any machines within our network with the board, including itself.

Here is the error:
==> ping 192.168.1.186
ethoc
Using ETHOC-0 device
ping failed; host 192.168.1.186 is not alive

Here are the environment variables I have set and saved from the u-boot prompt.
ipaddr: 192.168.1.35 (random ip address)
serverip: 192.168.1.186 (ip address of machine I am trying to tftp to)
gatewayip: 192.168.1.1
netmask: 255.255.255.0
ethaddr: 00:12:34:56:78:9a (random mac address)

100Mbps is being used for the Ethernet connection for the board (the LED indicating 100 Mbps is on).

Using tcpdump from another machine, can you tell if your ping requests are even hitting the network?

Dan

Doesn't look like it. I tried this as we're pinging from the board: sudo tcpdump -n src No packets were captured at all.

Just an update. I programmed a pre-built image of Linux into the Atlys board's flash memory since I haven't been able to resolve the networking problem. While the board can ping itself, it can't ping other machines, nor can other machines ping it. I tested this with tcpdump as well.

There aren't many places that a problem such as you describe can lie, but I am not an OpenRISC expert. Most of those experts seem to respond more to the mailman forum than they do this list--that's why I've been quiet for the past while.

However, risking and venturing being wrong and not knowing the answer at all, I'm going to suggest that your ethernet hardware is either not properly connected to the core or that it is misconfigured. Suppose we try this: do you get a console log from uboot when it boots up? I know Linux can be configured to provide such a log, and the u-boot sources look a lot like Linux sources. Can you then examine this log to see if the network device is properly detected and responds properly to the u-boot network driver?

Dan

U-Boot does provide me a log on boot up, though it's short and provides me with only one line of information regarding the network device.

Did you look at this at all? Does it sound like your problem?

Dan

Yes, I looked into that before. It sounds like the same problem, but the link to that commit is broken.

Is all of the net running at 100 Mbps?
