IoT Base Platform With RaspberryPi, WIZ850io : Ethernet Module Driver

I know RaspberryPi platform for IoT. Recently WIZ850io is announced by WIZnet. So I implemented a RaspberryPi application by Ethernet SW modification because I can handle a source code easily. You can test Ethernet Module Driver through RaspberryPi and WIZ850io. Please refer to the following step.

Step 1: Prepare Materials

Please refer to the following.

1. Raspberry Pi 3 Starter Kit

2. WIZ850io

3. UART2USB adapter

4. LAN cable

5. USB cable

Step 2: Hardware Connection

Please connect an USB, LAN cable, WIZ850io and UART2USB adapter.

You can get more HW info by the following site.

Step 3: Prepare Development Environment

Raspberry Pi 3

https://www.raspberrypi.org/documentation/linux/kernel/building.md

Step 4: Software

Linux Kernel : WIZnet Ethernet Module Driver for W5500

https://github.com/borg42/w5x00

Step 5: How to Run : Modification

I modified the source code to fit Raspberry Pi.

Step 6: How to Run : Result

I copied w5x00 module into Raspberry Pi.

Can you guide me to connect Raspberry and W5500, I have tried many times, but I don't know what connected to CS, RST, INT( on W5500), Is it CE0, BCM24 , BCM22 ?

Could you please help to run the driver. I've successfully compiled it for Raspberry Pi 3, uname 4.14.50-v7+.
insmod do say nothing, lsmode shows w5x00 module. But there is no wiznet interface in ifconfig. There are only 2 strings in dmesg:
[ 1976.627171] w5x00: 2.0.0
[ 1976.627218] w5x00 spi register succeed.
And I see no new devices in /dev.
Could you please tell, what shall I check?

Hello. thanks for the post.
I am afraid I am missing some piece, which is not mentioned here. I am trying these steps on RPI zero and W5500.

When trying to compile getting below error:

~/w5x00-master $ sudo ./compile.sh
make -C /home/pi/w5x00-master SUBDIRS=/home/pi/w5x00-master modules
make[1]: Entering directory '/home/pi/w5x00-master'
make[1]: *** No rule to make target 'modules'. Stop.
make[1]: Leaving directory '/home/pi/w5x00-master'
Makefile:12: recipe for target 'default' failed
make: *** [default] Error 2

Looking inside the Make file (I replaced your folder tree with mine)

obj-m := w5x00.o
w5x00-objs := module.o netdrv.o dev.o queue.o

#KDIR := /usr/src/linux-panda
#KDIR := /home/olaf/ee/red-brick/image/source/red-brick-linux-sunxi
#KDIR := /home/bingdo/project/raspberrypi_linux
KDIR := /home/pi/w5x00-master
PWD := $(shell pwd)

default :
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

clean :
rm -rf *.o
rm -rf *.ko
rm -rf *.mod.*
rm -rf .w5x00*
rm -rf Module.symvers
rm -rf modules.order
rm -rf .tmp_versions

and the target folder itself:

can you share result .ko file and insruction to deploy? thx

[SchmidtR]

I will give you my .ko file. Contact me via [e-mail].

[bingdo72]

I'm sorry. Currently I am not in charge of this job.

You can ask WIZnet about your needs. Refer to [e-mail]

Thank you.
