I had a NanoPi NEO2 working well with ARMBIAN 5.34.171121.

After apt-get upgrade, ARMBIAN has been changed to ARMBIAN 5.37.171208 with below firmware update:

Get:1 http://beta.armbian.com xenial/main arm64 linux-dtb-next-sunxi64 arm64 5.37.171208 [25.0 kB]
Get:2 http://beta.armbian.com xenial/main arm64 linux-image-next-sunxi64 arm64 5.37.171208 [14.7 MB]
Get:3 http://beta.armbian.com xenial/main arm64 linux-u-boot-nanopineo2-next arm64 5.37.171208 [222 kB]
Get:4 http://beta.armbian.com xenial/main arm64 linux-xenial-root-next-nanopineo2 arm64 5.37.171208 [318 kB]

 

Then the Ethernet port is no longer working. Kernel message shows MDIO register failure:

root@NEO2-ST0:~# dmesg | grep -i eth

Any hack do I need on device tree or driver to make it work again?

 

BTW: Is there any way to select specific version of ARMBIAN to build? 5.36 for example. Even if I checkout the specific release tag the build scripts will always switch to master and build the latest version.

 

Thanks & BR,

Yes - as I alreday did - you have to rollback to the old version and wait for the next version where hopefully the bug is fixed.

After the rollback you should freeze the kernel in armbian-config to avoid the ethernet problem while the fix isnt ready.

 

See my thread for this problem:

 

PS: The NanoPi Neo2 has a H5-CPU and you did ask in the part for H2/H3-CPUs

The normal NanoPi Neo has a H3-CPU

Should be fixed after this commit: https://github.com/armbian/build/commit/10816a3c68c5041ce8c2d9f49db0696b9fec83a4. A beta repository has also been updated.

Iam using

ARMBIAN 5.34.171121 nightly Debian GNU/Linux 9 (stretch) 4.13.14-sunx

Linux nanopineo23 4.13.14-sunxi64 #246 SMP Mon Nov 20 01:58:09 CET 2017 aarch64

 

Is this commit active, that I can unfreeze my kernel in armbian-config and do a apt update & upgrade to get a actual system and the ethernet port would remain useable?

Yes, it is.

Thanks - did work

u-boot does show (like on the old working kernel): Net:   No ethernet found.

 

but ethernet does work:

[    8.463845] RTL8211E Gigabit Ethernet 0.2:07: attached PHY driver [RTL8211E Gigabit Ethernet] (mii_bus:phy_addr=0.2:07, irq=POLL)
[   12.544959] dwmac-sun8i 1c30000.ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx

[   12.545009] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

That is normal. AFAIK no network support within u-boot for now or not enabled. 

 

Good!

Really great work!

It's possible but not really recommended. https://github.com/armbian/build/releases

Not all boards are created equal: OPi+2E Ubnt Xenial Next nightly -> 5.37.171221 = no ethernet; back to 5.34.171121 = OK.

Igor did the same for the Orange Pi Zero Plus (H5) as for the NanoPi Neo2

- maybe he isnt aware of the problem on the Orange Pi Plus 2E?

Many Thanks!
