Ethernet not working: Apalis iMX8 QuadPlus 2GB Wi-Fi / Bluetooth V1.0B with Ixora V1.1A

Hi all,

just installed the new minimal reference using Easy Installer on Apalis iMX8 QuadPlus 2GB Wi-Fi / Bluetooth V1.0B with Ixora V1.1A. Yet somehow it does not connect to the network using ethernet. connmanctl provides following output:

connmanctl> services

connmanctl>

cat /etc/issue
TDX Wayland with XWayland 5.4.0+build.11 (dunfell) \n \l
Apalis-iMX8_Reference-Minimal-Image

Ethernet should work, since I download the reference image using this. Am I doing something wrong?
On startup it shows following output:

[ OK ] Started Connection service.
[ OK ] Started Network Service.
[ 7.291023] Micrel KSZ9031 Gigabit PHY 5b040000.ethernet-1:07: attached PHY driver [Micrel KSZ9031 Gigabit PHY] (mii_bus:phy_addr=5b040000.ethernet-1:07, irq=305)

Below some more outptus.
Thanks and regards

Hi @PAR !

Just to be sure: you are connecting an ethernet cable to your Ixora board, right?

Did you check if the network that you connected to your module has a DHCP server running?

Best regards,

Hi @henrique.tx,
yes I connect to the ixora-board. I have an iMX6 with the same type of board and when I connect, it works just fine. But your answer implice, that our IT-department might have done something (which is possible).

thanks and regards
Patrick

Edit: According to IT this should work. But also, why does connmanctl does not show any ethernet service? usually it shows something like this: ethernet_985dad375f63_cable

Both LEDs of the ethernet are on (green permanent, orange blinking)
Best

Hi @PAR !

You are right. Something should show up using connmanctl sevices.

When you plug/unplug the ethernet cable on the ixora, are you able to see some messages about it on dmesg?

I get this when I unplug/plug:

[ 5098.155669] fec 5b040000.ethernet eth0: Link is Down
[ 5102.853668] fec 5b040000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx
[ 5102.861653] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

Also, could you try to establish a direct network connection to your PC? Or maybe use a router with your PC and your module specifically to test the ethernet of the module?

Best regards,
