>Description:
When trying to use NanoPi NEO emac (ethernet) it seems no longer
working.
It worked fine with netbsd-9 so this seems a regression between netbsd-9
and netbsd-10 (and newer).
I have tested that with both netbsd-10, netbsd-11 and netbsd-current
available on armbsd.org as Saturday and today and none of them have
working ethernet (2026-10-19).
For completeness here the corresponding dmesg lines (I have "obscured"
the MAC address both here and in later sections):
emac0 at simplebus1: EMAC
emac0: Ethernet address f2:00:3e:xx:xx:xx
emac0: interrupting on GIC irq 114
ukphy0 at emac0 phy 1: OUI 0x0088a0, model 0x0000, rev. 0
>How-To-Repeat:
Run:
dhcpcd emac0
Or:
ifconfig emac0 192.168.1.28/24 up
And try to ping some host in the network and observe that there are no
packets and the green LED is always on.
I can observe that the UTP cable is properly recognized if plugged or
not though. Here I have kept the default of the image by having dhcpcd
enabled. When it is plugged I can see (notice "media" and "status"):
emac0: flags=0x8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
capabilities=0x3f00<IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx>
capabilities=0x3f00<UDP4CSUM_Rx,UDP4CSUM_Tx>
enabled=0
ec_capabilities=0x1<VLAN_MTU>
ec_enabled=0
address: f2:00:3e:xx:xx:xx
media: Ethernet autoselect (100baseTX full-duplex,flowcontrol,rxpause,txpause)
status: active
inet6 fe80::37f7:217c:9336:d0e4%emac0/64 flags 0 scopeid 0x1
inet 169.254.30.240/16 broadcast 169.254.255.255 flags 0
When it is not plugged (notice "media" and "status"):
emac0: flags=0x8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
capabilities=0x3f00<IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx>
capabilities=0x3f00<UDP4CSUM_Rx,UDP4CSUM_Tx>
enabled=0
ec_capabilities=0x1<VLAN_MTU>
ec_enabled=0
address: f2:00:3e:xx:xx:xx
media: Ethernet autoselect (none)
status: no carrier
inet6 fe80::37f7:217c:9336:d0e4%emac0/64 flags 0x8<DETACHED> scopeid 0x1
inet 169.254.30.240/16 broadcast 169.254.255.255 flags 0x4<DETACHED>
I have another NanoPi NEO with:
NetBSD armv7 9.0_STABLE NetBSD 9.0_STABLE (GENERIC) #0: Tue Jun 30 18:49:17 UTC 2020 mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/evbarm/compile/GENERIC evbarm
And there emac is properly working. So it is likely a regression between
netbsd-9 and newer. I have also switched the uSD card to double-check
that there are no hardware issues in the spare NanoPi NEO I am currently
testing.
>Fix:
N/A, sorry!
If you have any suggestion on how to possibly debug that and/or
help further I am happy to try!

For completeness, attached you can also find the output of `dmesg -t'
for netbsd-9 (dmesg-9.txt) and netbsd-current (dmesg-current.txt).

Just for the record, I have tried to substitute the DTB on -current
with what I had from the last netbsd-9 working system but I have the
same symptoms and emac is still not working.
I will try to further bisect that.
Thanks to <skrll> for help, pointers and suggestions on the process!
