LAN7800 support
-
Hello, I'm trying to use LAN7800 with a VOXL2. I'm on SDK 1.4 with an EVB-LAN7800LC-1 evaluation board.
I've seen that the lan78xx driver requires Linux kernel 4.3+ but even though the VOXL is on 4.19.125, it looks like there's support for lan78xx?
I've confirmed that the adapter works on my Windows laptop, but the following is what happens when I connect it to the VOXL2 on the M0151's port

I've seen that the lan78xx driver requires Linux kernel 4.3+ but even though the VOXL is on 4.19.125, it looks like there's support for lan78xx?
I've confirmed that the adapter works on my Windows laptop, but the following is what happens when I connect it to the VOXL2 on the M0151's port

I am not sure about this one.. If a higher kernel version is required and the existing driver does not actually work, then maybe it is not a big surprise!
the kernel module is in the build, as specified in the config file here : https://gitlab.com/voxl-public/system-image-build/qrb5165-kernel/-/blob/qrb5165-ubun1.0-14.1a/arch/arm64/configs/vendor/kona-perf_defconfig#L328
Some info about the driver : https://gitlab.com/voxl-public/system-image-build/qrb5165-kernel/-/blob/qrb5165-ubun1.0-14.1a/arch/arm64/boot/dts/vendor/bindings/net/microchip,lan78xx.txt
You could try to pull source code from updated driver for this device from a newer kernel, drop it into the voxl2 kernel build and build the kernel with new driver. I think some users on this forum were able to do something similar with another device (not ethernet adapter).
Maybe try another ethernet adapter?
For example,
