How to stop debug messages in lwIP?

KKjel.1

Hi

I have a project using lwIP, created by STM32Cube.

It works fine, but I really want to shut OFF the debug messages.

I have searched and tried a bunch of different things, but nothing seems to be able to stop it.

 

Example of error/debug message: "netif is not up, old style port?" failed at line 744 in C:\..."

 

Thanks

Add a global macro definition " LWIP_NOASSERT"

Hello @KKjel.1,

Could you please verify that you don't have any debug macros enabled in the lwipopts.h file? This might be the reason for the debug messages you are seeing.

There is no DEBUG macros in that file.

Here is the complete file:

Add a global macro definition " LWIP_NOASSERT"

Thanks, Passerby, nice and easy, and it works !

 

Kaare

"netif is not up, old...." is a error message , you should pay attention to that.

Not printf does not mean that errors disappear

 

 

Yes, I am aware of that. But the error message is because I have not attached the ethernet cable :)

 

The problem is that the debug messages is using a printf impleentation which completely destroys every timing in the application.

It can in some cases make the watchdog trigger...

So I just want to shut it down when not debugging.
