@Koen,

Please try kwboot this version:

uboot.2016.05-tld-1.t5325.bodhi.tar

fortis & Koen,

I think you should try kwboot the previous version to see if the network is working.

uboot.2016.05-tld-1.t5325.bodhi.tar

bodhi,

I only flashed these:
uboot.2017.07-tld-1.t5325.bodhi.tar
uboot.2016.05-tld-1.environment.bodhi.tar

Networking was working fine with those.

Let me make sure I understood.

Does it not working in u-boot console now, if you power up and interrupt console and ping the router?

Or it is not working after the kernel booted?

Or both not working?

All,

I was able to create a failure case with my box!

Please try these 2 test to see my assumption is correct.

Test 1

Unplug the power cord.
Wait for a while, at least 10 seconds.
Power up, interrupt serial console
Ping the router 5 times


Test 2

Unplug the power cord.
Wait for a while, at least 10 seconds.
Power up, interrupt serial console
Ping the router
If ping was not successful, unplug the ethernet cable, wait a few seconds and plug it back in and ping the router again.

Re: HP 5325 ethernet stopped working
October 26, 2018 03:36PM
fortis,

That's too bad! I thought it might help to make sure that the multiple pings would help to eliminate false negative.

What I observed while testing was: some of the times (I cannot repeat this test each time), when the box is powering up, u-boot running, and the network connection was not up fast enought, so I would get 1 failed ping. And then when I start pinging the router again, it would establish connection.

Another observation: when you tried kwboot with the 2016.05 u-boot, the PHY was timed out. That was the behavior I expected, since the network chip was in incorrect in that u-boot version. I've fixed this in the 2017.07 u-boot.

Normally, my box ethernet works fine with both cold boot or warm boot. So it is not easy to make it fails. FWIW, the other end of my cable is a Gigabit switch. That switch is connected to a wireless bridge.

I can't think of any reason that it would not work in yours and Koen's box :) other than HW. But HW does not make sense because you both have the same problem.

UPDATE:

I'm asking Ray to try this on his box.

Hi bodhi,

I'm getting the same result as fortis91 when doing the 2 tests. I've tried kwboot multiple times but have never got the box to respond. Not sure why since I know the serial connection works fine. I still have backups of the stock mtd0 and mtd3 partitions. Is it worth going back to stock and test the networking to see if it might be a hardware problem?

Definitely! that would help eliminate some unknowns. This is one of boxes that I think I got every thing figured out, but we'd never know, because we saw there are some differences in various production lots (e.g. flash chip, so who knows what else).

Re: HP 5325 ethernet stopped working

Looking through the DTS files for some of the other kirkwood systems the ethphy is configured with a compatible line. For instance the kirkwood-dockstar.dts has the following for ethphy0

        ethphy0: ethernet-phy@0 {
                compatible = "marvell,88e1116";
                reg = <0>;
        };

Which makes me wonder if there would be less problems with the kirkwood-t5325.dts if we modified the ethphy0 definition to:

        ethphy0: ethernet-phy@8 {
                device_type = "ethernet-phy";
                compatible = "marvell,88e3016";
                reg = <8>;
        };

I've been using a USB Ethernet adapter on my T5325 for some time now as I was constantly having problems with it recognizing the internal port correctly.

That's a very good point. But because Koen's and fortis's problem occured in u-boot (before the kernel loaded), I think it is perhaps something else about hardware that we don't know about (could be the differences for various releases of this box).

Now that I know you also had some problem with the network, I think that we might need to revisit the GPL and search for hints if there really are more than 1 HW configuration.

The puzzle is that I don't have this problem even though I am running the same u-boot and kernel, and DTB, as everybody else!!!. That's why I thought perhaps hardware configuration plays a role in this problem.

Re: HP 5325 ethernet stopped working

OK I will have a look at going back to stock to see if it is a hardware issue. Without working ethernet the device is of not much use so may as well give this a try. Accessing the mtd partitions from Debian doesn't work properly on my box at the moment so I guess the best way is via serial connection. I've not got much time this weekend but will start reading up on this so I've got a better idea of the steps involved.

Or perhaps before going back to stock, you should go through the new u-boot installation again in Debian first to see if it helps.

Re: HP 5325 ethernet stopped working

fortis,

Before doing that, could you try this test in serial console. Basically we want to set the ethaddr to a local MAC address. This MAC addr was randomly generated and set as default in the default envs image "uboot.2016.05-tld-1.environment.64K.img".

Note that it is OK to use this MAC permanently, since it cannot be reached from outside your network. If you have another box that you want to use a local MAC address, then you should generate a new one using a tool (I could upload that binary here for everybody to use).

Power up, interrupt serial console and
setenv ethaddr '52:3b:20:9c:11:51'
saveenv
reset

After reset, interrupt serial console again and do some tests like I suggested before (i.e. pinging the router a few times).

If you still have network problem, power down, unplug the power cord for a while, and then cold start. And repeat the tests.

In Debian, use ethtool to list the info

ifconfig -a
ethtool eth0
