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 Platform Device 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
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
Step 4: Software
Linux Kernel : WIZnet Platform Device Driver
I modified menuconfig to use WIZnet Platform Device Driver as module type.
Step 5: How to Run : Result
I copied w5100, w5100-spi modules into Raspberry Pi.
