Hi,

I currently have a project with a Toradex Colibri IMX8X SOM board whith an
onboard Micrel KSZ8041NL Ethernet PHY.

The hardware is described in the devictree properly so I expected that the
onboard Ethernet with the phy is working.

Currently I'm not able to get the link up.

I already compared it to the BSP kernel, but I didn't found anything
helpful. The BSP kernel is working.

Do you know if there is something in the kernel missing and got it running?

dmesg output might be useful.

Do you have the micrel driver either built in, or in your initramfs
image?

Hi Andrew,

the driver is built in.

In [1] you find the dmesg log from the 5.19 kernel. I also added the 
DEBUG built flag for the relevant phy and network drivers.

As reference the bsp kernel 5.4.129 kernel [3] works without issues as 
you can see in [2].

Thanks,
Philipp
