Hello,
We are trying to develop a simple ethernet project with the K64 Kinetis. For that we are using the fNET stack and right now we are just tring to add the stack to our project according to the tutorial http://fnet.sourceforge.net/manual/how_to_add_fnet.html .
We have already add the path on the project settings in order to point to the new stack folder, but we are still getting a No such file or directory error besides the fact that the folder is there.
Can you please help us figuring out what is the problem? We did not yet, place any code on main.c just the #include “fnet.h” and are getting this error.
Thank you in advance
Regards
Hi,
I followed the same tutorial that you mentioned and was able to add the fNET stack without any issues. For that I started by creating a plain K64 project, then I downloaded the fnet files from the FNET Project Home Page: GitHub - butok/FNET
After this, I copied and pasted the fnet_stack folder into my project's source file and then proceeded to add its path into the project (just as I'm about to show in the following images):
1) Copy fnet_stack to the source folder:
2) Go to the project's properties, and in its settings include the path to fnet_satck (after including it, click apply):
3) Go to the source properties (right click on the folder, and then choosing properties) and include the path to the fnet_stack from the workspace option (after this click on appy and close):
4) Add the fnet_user_config.h file (which I copied from one of the demo projects inside fnet_demos which is part of the folders you download from the git repository):
5) Go to the fnet_cpu_config.h file and enable the define corresponding to your board (as I'm using the k64, I only enabled its define):
6) Build your project and you should see that the issue you mentioned is no longer presented.
I hope this can help you.

Hello
As a token of appreciation I would like to share my experience after successfully compiling the project base on Ricardo’s steps.
After the Ricardo’s steps I had to add some parts in order to accomplish my simple goal of performing PING on my Kinetis MK64FN1M0VLQ12 and KSZ8081RNA. It may help others.
Here they are:
7) After Ricardo's step 6, I had to comment the following interrupt function, as it was beeing set twice
8) I also had to add the fapp_config.h from one of the fnet stak examples as done for the fnet_user_config.h previously
9) In order to define the IP and MAC you should open the fapp_config.h and set it in the define FAPP_CFG_ETH0_IP4_ADDR
10) Using IDE MCUXpresso you don't really need to set the pins on ConfigPins tool for the fnet_stack to work, as they are set on fnet_mk_eth.c
11) After running this script you should be able to open a Command Prompt and ping 192.168.0.5 and this is the code that worked for me:
[CODE]
#include <stdio.h>
#include "board.h"
#include "peripherals.h"
#include "pin_mux.h"
#include "clock_config.h"
#include "MK64F12.h"
#include "fnet.h"
