The IP application in the second…. The BSP for this project will also have to be modified slightly. Without his contribution I think I would thtorial have been able to create this article. Another thought I have: Thanks for the quick responce. Could it be some linker setting i have missed? Thanks for a great tutorial. It starts with a DHCP request and then does some IP broadcasts and at the end releases the address and closes the connection: My tutorlal have a good relationship with Freescale, now NXP.
There is an updated utility module available on https: That might make a difference, even a possible compiler bug?

If you want to experiment, you can play around with the software by sending more packets, or different kinds of packets. With the help of Processor Expert many aspects of the networking application get simplified, and after some tweaks the Kinetis SDK is now working too. Noriel Christopher Tutroial on February 26, at This worked for me also! But when I compile I get an error of make makefile: The project can be found on http: The problem is if the received frames are ldip in an interrupt context and passed up the lwip stack.
I will try from tutofial playing attention to the points you have mentioned. With the network cable plugged in, the application writes the status to the semihosting console. To be able to read the output of the echo server application, tutroial need to use a terminal program such as Putty.
Hi Erich, Thanks for your response. The Kinetis Tutotial utilities and internal printf routines do not play well with semihosting, so I had to disable it:. To test that the echo server is actually doing its job and echoing received packets, you will have to install software that allows you to send and receive arbitrary packets. What it means is that you called an API function which is not supposed to be called from an interrupt.

With the terminal program open, we can now load our ZedBoard with the bitstream and then run the echo server application. Do you have any example designs tutoriap know-how for driving multiple ethernet ports simultanously with lwIP? The settings I need to check are in the Clock Manager:.
Act on data in real-time. And about the course material: I have not upgraded or changed the SDK for that project, so it sounds based on your feedback there are problems with the newer SDK. I have not published that to the public, and it probably does not make a lot of sense. In this example is your Freedom Board server or client? I assume I can do this in Linux?
Hi Camilo, yes, I have considered that already multiple times. The issue is that I cannot see anything in the componeents view.
I strongly recommend that you perform these modifications to the sources in the Vivado installation files — not the sources in the BSP of your SDK workspace. I have hunted around but have not found anything about exiting Eclipse. There is a version of the project for the ZedBoard and the MicroZed. Now that the application is running successfully, we can test the echo server by sending packets from our PC to the ZedBoard and looking at what gets sent back.
In your example the settings are in a spreadsheet like format the current version has tabs and windows and the setting names are not the same or missing. A long-time-waiting thing on my to-do list finally has been accomplished: Have you ever know about FNET? If this requires some file changes, a confirmation dialog might show up which I confirm with OK:.
The Kinetis SDK is not compatible to anything else.
Are you using the latest project and files from GitHub? It takes many pieces to build the basis of a network IP application, turorial lwip for sure is a good and well documented open source project.
