Recently WIZwiki-W7500 platform was announced by WIZnet. So I implemented a firmware of WIZwiki-W7500 by using TFTP because I can handle a source code easily.
Please refer to the following step.

Step 1: Prepare Materials

Please refer to the following.
1. WIZwiki-W7500 board. ( http://www.shopwiznet.com/wizwiki-7500 )
2. Mini USB cable
3. LAN cable

Step 2: Hardware Connection

Please connect an USB cable and LAN cable.
You can get more HW info by the following site.

Step 3: Prepare Development Environment

I prepared GCC development environment by the following site.
http://lghmms.cafe24.com/how-to-build-a-development-environment-with-gnu-arm-java-jdk-eclipse-cygwin/
I installed GNU Toolchain, Java JDK, Eclipse, Cygwin.
If you install all tools, you are ready for running this project.
You can use a Configuration Tool by the following temporarily.

Download

Step 4: Software : GitHub Repository

I opened source codes of this project in GitHub.
https://github.com/bingdo/TFTP_WIZwiki-W7500_Eclipse
You can download this project files. And then import project into Eclipse.
After compile, you can run TFTP application of WIZwiki-W7500.
This project is open for everyone. I expect your participation to improve a quality of project.

Step 5: How to Run : Test Result

1. To program FW into a target.
2. To reset a target and insert MAC address.
3. To search a target by Configuration Tool.
4. To check Host IP and Options.
5. To change IP, Gateway properly.
6. To search a target by Configuration Tool again.
7. To select "F/W Uploading".
8. To change Server IP, File Name properly.
9. To press OK.
10. Check a version of new FW through terminal program.
You can see the test result by the video.
Thank you for your attention.
