How to enable w5500 ethernet module in raspberry pi

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello Everyone,

I'm trying to interface w5500 Ethernet module (SPI to Lan) with Raspberry Pi Zero but it is not initializing.

Packages installed:


kmod-spi-bcm2835 - 5.15.134-1
kmod-spi-bitbang - 5.15.134-1
kmod-spi-dev - 5.15.134-1
kmod-spi-gpio - 5.15.134-1
kmod-spi-ks8995 - 5.15.134-1

I see

ls /boot/overlays/w55*
/boot/overlays/w5500.dtbo

I have tried enabling in /boot/config.txt

1.
dtoverlay=spi-bcm2835
dtoverlay=anyspi,spi0-0,dev="wiznet,w5500",speed=30000000

2. (Works in Raspbian OS)
dtparam=spi=on
dtoverlay=w5500

Please let me know how i can solve this issue. Thanks.

2

does it work in Rasbian, or whatever the RPi OS is called ?

3

Yes the below edit in config.txt will enable the interface

4

in that case, what modules does Rapbian load, and which kernel version does it run ?

5

Run ethtool -i eth5 to determine driver in use (also run modinfo modulename to determine its version and running kernel)

Kernel:

uname -r
6.1.21+
uname -a
Linux raspberrypi 6.1.21+ #1642 Mon Apr  3 17:19:14 BST 2023 armv6l

Modules loaded (SPI)

lsmod | grep spi
w5100_spi               7440  0
w5100                  12989  1 w5100_spi
spidev                  9491  0
spi_bcm2835            11936  0

This comes up in both OS

cat /sys/class/spi_master/spi0/spi0.0/modalias
spi:w5500
cat /sys/class/spi_master/spi0/spi0.1/modalias
spi:spidev

Trying a snapshot might be a good idea.

@frollic not sure what you meant by snapshot here

Please OCR your image. Does not have any ethtool or modinfo.

And modinfo?

You can ask to package in-tree kmod via github bug tracker, or better (faster, to make into next stable release) try yourself and make a PR.
