Kinda upset at the lack of response to GBe issues

[MarkHaysHarris777]

Well, we know that for a short time (due to parts shortages) they used another vendor's chip. What we need to do is identify the vendor's ieee assigned prefix.

Did you try a mac address that at least turns off the local bit ?

[amc2012]

Second least-significant bit was 0.

[MarkHaysHarris777]

Well, I think I'm making progress here.

... I have two boards (out of three) of which I am able to discuss; one of them GbE works, and one of them GbE does not work !          Pine(A) GbE works;  Pine(B)  GbE does not work. 

(First off, both boards function, and both boards do 10/100 perfectly)

All of this used the following setup:

all short cat6 cables   1M
Lenovo Mint Linux T61 notebook  server   ( iperf -s )
ubuntu & debian builds (alternately running on both pine boards as iperf -c clients)
ipv4 disabled
mac addresses as listed above, local bit set off

---

I will update the poll shortly;  some slight more testing to do first--- for now, I have one board that functions with GbE and one board that does not function with GbE.  The more of these we can find the better.   My boards differ in that the one that does not work has a later serial number and is marked [ 04.12 ] where-as the board that GbE functions is an earlier serial number and is marked [ 04.11 ].

So, still frustrating, yet making progress.

These numbers were obtained using the working board Pine(A) , ubuntu , while running on battery...  I almost doubled my numbers; this is repeatable !

... and this even though my ac power feed is filtered !   Aparently not filtered engouh for 1Gb.

[pfeerick]

Yes, I had gone to try longsleep's fix (he wrote to me this morning), but I am one of the lucky ones who does not have a MAC address on the bottom of my PINE. Only have a serial #. So no dice for me.

If you want to try a complete MAC, you can use the one off my board, since it's only used at the LAN level... 0006dc8b50a6

Although, since you tired the first six characters, I doubt the rest will make any difference. 

Hey MarkHaysHarris777... making me jealous now... you have 2Gb pine64s... and I only have a 1Gb one!

btw, the V1.1 is the same on my 1G board, but the different number you've highlighted on your two boards is 03.17 on mine... maybe it's a Month.Date of manufacture code?

That's my guess as well.

[amc2012]

Makes sense. Mine is 05.17, as stated in the poll thread. I got mine very late, despite being a February backer, so the 05.17 seems accurate.

[blairac]

I have two boards (both 2GB with wifi/bt). One works when set at 1000Mb/s. One does not work well (sporadic). I run ubuntu on the one that works and debian on the one that does not (however it does work consistently when I run at 100Mb/s).

What information can I provide that may be useful diagnostically? (and where is the poll that is mentioned?)

The poll is at this link.

... take the poll, then read the first post (below the poll) and provide your data... both the card that works and the card that does not work.  You can vote twice, so if you have one that works, great report it.  I you have one that does not work, that's good too... report that !

[pfeerick]

You can vote twice.

No, you can't. Once you've voted (once), you can only see the results of the poll. That doesn't stop you from commenting in that thread multiple times, or indicating that with the same SD image, but with two difference devices, you get different results, etc.

I built the poll.  I also edited the poll, to allow for multiple votes (2).

... this when I realized that some folks (like myself) have multiple boards, some which work, and some that do not.
