beagleplay wired ethernet doesn't receive packets

General Discussion

The pre-installed kernel on a recently purchased BeaglePlay board appears to be able to transmit packets, but can’t receive them.

Here is output from ‘ifconfig eth0’ for my board:

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet6 fe80::3608:e1ff:fe84:fa08 prefixlen 64 scopeid 0x20
ether 34:08:e1:84:fa:08 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 44 bytes 9451 (9.2 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

Note that it doesn’t have an IPv4 address, presumably because the board couldn’t
receive DHCP packets.

The link led light is on for the wired ethernet connection. I tried various commands to
manually configure eth0 (using networkctl, ip, ifconfig, and route) to no avail.
For example, I tried editing /etc/systemd/network/eth0.network to specify a static IP
address. With that configured I can transmit packets, but not receive them.

I get some error messages from u-boot when the board boots, here is the serial console
output during boot:

Later on, during kernel boot, I get these messages related to the ethernet driver:

When I run a recent Debian-xfce image from an sdcard, the wired ethernet works, so I suspect a
problem with the u-boot version or device tree in the pre-installed image.

Is there an updated image available that reflashes the distribution that is pre-installed on the mmc?
What is that distribution? /etc/os-release says it’s Debian 11.

I’d like to play around with the pre-installed VSCode - but I don’t think that’s available in the Debian
downloadable sdcard images, is it?

Any tips would be appreciated.

Hi @tbird20d

Yeap, that was me, it was a very early build that made it to the production eMMC’s…

Without Ethernet working, it’s not trivial, unless WiFi works…

You can install our build of mainline u-boot via:

sudo apt update
sudo apt-get install bb-u-boot-beagleplay-mainline

Then run these two commands, first to copy the files to /boot/firmware/ the second to update boot0…

sudo /opt/u-boot/bb-u-boot-beagleplay-mainline/install-microsd.sh
sudo /opt/u-boot/bb-u-boot-beagleplay-mainline/install-emmc.sh

Or, you can use our new bb-imager: (windows is broken) (clone of rpi-imager) Index of /public

and select the ‘xfce flasher’ option…

OK, Thanks.

I did have wireless working, so I installed the newer u-boot, but it doesn’t seem to help.

I can send dmesg output if needed. It’s possible I didn’t restore /etc/systemd/network/eth0.network to its original form (I unfortunately made some edits before I thought to save off the original). Any more ideas?

Which kernel is it? uname -r?

On mainline for the network phy, we’ve moved from mdio-gpio to mdio: arm64: dts: ti: k3-am625-beagleplay: Use the builtin mdio bus - kernel/git/torvalds/linux.git - Linux kernel source tree

and then a reset fix… arm64: dts: ti: k3-am625-beagleplay: Fix Ethernet PHY RESET GPIOs - kernel/git/torvalds/linux.git - Linux kernel source tree

One option, would be to test a mainline kernel, this will pull in a 6.10-rc7

sudo apt-get install bbb.io-kernel-6.10-k3

There will be a backup copy of: /etc/systemd/network/eth0.network at /etc/bbb.io/templates/eth0-DHCP.network for reference: bb-usb-gadgets/suite/bookworm/debian/eth0-DHCP.network · main · BeagleBoard.org / repos-arm64 · GitLab

Haven’t seen a PHY fail like on a BeaglePlay yet…

Old uname -r was ‘5.10.153-ti-arm64-r86’

I installed the new kernel (6.10-rc7) and the ethernet came up. Woot!

Is there a way to turn off random MAC address assignment? I have a lot of configuration in my test lab that I have to change when the IPv4 address changes.

I assume this is coming from this, so it’s a driver config option?:
[ 2.862443] am65-cpsw-nuss 8000000.ethernet: Use random MAC address

BTW - Thanks very much for the help!

Awesome, glad it came up!

Is it actually coming up random, or just the driver being vocal for no reason? I’ve got a dhcp table for mine, so i just haven’t noticed they changed…

We should be able to override it in the link section of systemd-network: systemd.link

thinking…

/etc/systemd/network/10-eth0.link

[Match]
Name=eth0

[Link]
MACAddressPolicy=none
MACAddress=11:22:33:44:55:66

Regards,

OK - so I double-checked, and it looks like the MAC has been consistent between runs.
(So I guess it’s just the driver being vocal for no reason.)

I’m not sure why my DHCP server dished out a new address, but it looks like I’m set.
Thanks.
