Hi, I have problem with ethernet.
One day Beaglebone ethernet work correctly but after that I can't get
access to ethernet.
During boot I will got message:
[ 4.031072] PHY 0:00 not found
[ 4.034313] PHY 0:01 not found

ifup eth0 give results:
root@beaglebone:~# ifdown eth0

RJ45 connector orange led blink couble times durin boot. It is same is
cable connected or not. If bone is long time without power the orange
led is on at start up boot but go off during boot. At run time leds
are off, is cable connected or not.
I have tried with power and without it. Several different Ångström
images eq. 16.11, 13.12 and 22.12 dated versions, but no working
ethernet.

I found couple similar treads by google but no help from those.

Have anybody any idea what I should do that ethernet will work again?
Or is the board broken :(

Something new, the board was one day without power and now network
works a couple minutes. After that ethernet miss, I used ping to see
condition of ethernet. After rebooting no ethernet.
That can be PCB issue...

Have anybody similar operations?

Well, yes. On my BeagleBone the ethernet connector LED is orange most
of the time regardless of whether or not there is a cable plugged in.
I tried different cables and routers but no "sustainable" change.

On rare occasions the green LED starts to blink very quickly (~ 5 Hz)
after plugging (ethernet autonegotiation?) a cable. But it seems to
have no positive effect on the software.

ifup eth0 gives following result:

I have the 2011.12.13 Angstrom image running.

In another thread I read the BeagleBone is "picky" with regard to the
ethernet cable used. Any details about when a cable is "good" from the
BeagleBone's perspective?

flobe: I have same Angstrom image than you at now. I read some were
with it the ethernet should work.
I can see that on you board ethernet PHY 0:00 is found.
> [   83.679992] CPSW phy found : id is : 0x7c0f1
My situatuin is still:
[ 4.420247] PHY 0:00 not found
I tried with several cables and different switch ports, but no
difference. But seems that omap chip didn't find PHY-chip.

Situation is strange because ethernet work short period if board is
unpowered over 12 hours. One possibility with my case is that clock
source (crystal Y4) of PHY have bad stability. But I don't have tools
to measure it. Like "Short period aging of crystal" I don't know what
is right word for that.

Last time when ehernet work I tried to use cold spray to see if any
effect and ethernet stop working immediately.

I received a board a couple of days ago, with exactly the same
behavior as Kari. When I first powered it up the ethernet port worked
fine, but after maybe 10 minutes the link went down. To begin with I
could restore link by rebooting the board. but after about an hour it
required a power cycle, and now it does not work at all.

I have also tried with several cables and different switch ports, to
no avail.

I also get the 'PHY 0:00 not found' error message, both when booting,
and when issuing ab ifup command.

Quoting Jorgen <jsabra...@gmail.com>:

Are you sure your power supply is capable of delivering enough
current?

Yes. I started using the board powered from USB, and to begin with the
ethernet port worked fine. After I began to see errors, I tried using
a 5V 3A supply, but this did not change anything.

I also have this problem. I am running Angstrom-Cloud9-IDE-eglibc-ipk-
v2011.12-core-beaglebone-2011.12.26.img and getting the same results.
Ethernet stops working after a while.

I have tried using two different 2A 5V power supplies, running off of
USB power, and a bunch of ethernet cables to no avail.

Some more information: I haven't checked the PHY supply, because it is
shared with a number of other devices which are still working fine
(USB2412HUB, FT223, EEPROM), so I have assumed it is OK. I checked the
ethernet crystal (Y4), and it is oscillating at 25MHz with a good
amplitude. I also checked whether the PHY is sending link pulses on
pair A, and it is not. So, at least in my case, it looks like the PHY
is toast.

I guess I'll be returning my board. It is rather worrying that there
are already this many cases of problems with the PHY.

On my board the phy is not even warm.

This issue is also being discussed here:

I see the same behavior as Kari: if I leave the board powered down for
a while (hours) then the ethernet will work for a short while.

Another thing I have noticed is that the yellow LED in the RJ45 jack
will turn on when the board is powered up. If it stays on, then the
ethernet port will work when I insert a cable. But usually it just
blinks, as if the PHY is powering up, and immediately powering down
again.

My first BeagleBone had the same issues: PHY 0:00, no link at all after
it run for ca. 12 hrs. It went even worse: even the LED went mad without
even booted, later it stopped booting at all (You may find some postings
in the list archive):

e.g.

http://dl.dropbox.com/u/28187/IMG_0495.MOV

My distributor (Germany) was kind enough to handle the RMA for me after
I submitted the RMA request on http://beagleboard.org/support/rma

I've not yet received a feedback, but I returned the board just a little
over a week ago.


best regards
Roland

You won't be receiving any feedback anytime soon. Watterrott holds all the RMAs until they have several and then they ship them for repair. We won't be getting it for months.

Sending it directly to you would have cost me 34€ only for shipping (DHL, online).
So imho it does make sense to collect RMAs per distributor.

We learned that a long time ago. we are working to get the board back for Watterott as soon as we can. We really need to see what is going on from a HW standpoint.

Same problem here, it's been working for a couple of days but some
minutes ago the ethernet has stopped working with the same error message:

Would you be willing to request an RMA and give us a chance to look a the board? So far, nobody will let us see one. We will replace it with a new board.

Make sure you request the RMA before you send the board in.

My board (which arrived last week) worked fine, until I performed an
'opkg upgrade'. Now I am in the same boat with this ethernet issue. A
little frustrating to be sure as I'd read this thread, and didn't
connect the dots that maybe it was related to newer software. I am
going to rescue some python code from the microsd card and attempt to
wipe the filesystem with an earlier image, and see if I can get back
to ground 0. Will report back with any success (or failure).

Quick followup, it was too early/late... my issue was different than
the topic of this discussion. I was able to bring the network up with
an ifconfig eth0 up, and a new image fixed the issue. Sorry for the
noise.

I too, lost the ethernet port with the 'opkg upgrade'. So I carefully installed what I needed. I also tried to get a mySql 5 server running and found that the ssh process was being killed off for some reason.

I had to format and build the images on the micro SD card to get it back. I used 'nmap' running on another box to check whether the ssh process was running. Often it was not.

HI,

Are there any news regarding the issue with the PHY on BeagleBone
rev:A3?

It seems that I also have the same problem. The PHY drops the link
right
after power-up.
If I unplug the Ethernet cable then the yellow led starts flashing and
finally comes up, but it drops soon when I plug the cable.
The PHY chip is quite warm touching by hand. (The CPU and the FTDI
chip
also warm, at least if I compare them to the OMAP3 on BeagleBoard C2
at
same 500MHz clock.)

I have the following messages in dmesg:
[ 0.300345] davinci_mdio davinci_mdio.0: davinci mdio revision 1.6
[ 0.300365] davinci_mdio davinci_mdio.0: no live phy, scanning all
[ 0.300565] davinci_mdio: probe of davinci_mdio.0 failed with error
-5
[ 4.789170] PHY 0:00 not found
[ 4.792500] PHY 0:01 not found
[ 1088.508603] PHY 0:00 not found
[ 1088.511963] PHY 0:01 not found

I have tried both the Angstrom sdcard and the Agora one from TI.
Actually the link drops before the kernel starts. I tried to stop the
boot process and see what can I do wit u-boot, but no success. Link
was
dropped.

Can it be a problem with u-boot? Have anyone tried to compile a new
one?

Thanks for any update in advance.

Best regards,
Blaise

We are looking into the issue. We have only been able to look at one board so far and that appears to be a manufacturing issue. We received two more boards yesterday that we are looking into now. So nothing new to report.
 
I suggest that you request an RMA so that we can look at your board as well. We only have about 8 cases like this out of the 5000 boards we have shipped and it is tough to debug a board via emails.
 
I will say this, the yellow LED i supposed to turn off if you have a 100M link. That is normal and not an indication of wether or or not the link is up.
 
Gerald

same problem here, the first BeagleBone would sometimes boot up

Is there anything I can do, bearing in mind both my Pandaboard &

Remove R219. We have been discussing this extensively on the mailing list and right now that is the easiest solution.

Hi Gerald, 

I have the A2 board, is there an equivalent of this R219 resistor?

Thanks

No. R219 is only on A4
 
As to A2, it does not work reliably at all on Ethernet. You need to get a production unit A3 or A4. A2 is not a production unit and we never produced it.

No working ethernet either (it never worked), see attachment of the output during startup.

Tested with (different) working ethernet cables (that is to say that other devices like laptops or Nanode's establish working ethernet connections).

Beaglebone Rev. A4

Shall I request a RMA?

RMA is up to you, but most people have no issue taking care of the issue themselves. Just watch video on how to do it.

Hi Gerald,

I just got an A3 (from Arrow Electronics) that's also reporting:

[ 6.992879] PHY 0:00 not found

[ 6.996122] PHY 0:01 not found


It was working at first but over time, the PHY stayed up for shorter and shorter periods of time.  Now it won't connect at all.


I'm in Dallas, Texas, not too far from TI headquarters.  Would you like to examine my board, or would you like me to RMA it through Arrow?
