Yeah, you can disable it, you just have to commend the serialPoll function in main.c. It is a quick and dirty fix but it should do the trick. Right now the makefile doesn't support building without serial but it should be something trivial to add.

I've been meaning to check if disabling all the serial code would allow Ariadne to use a smaller boot flash section size. Of course this will change the procedure for writing the network settings to EEPROM since you couldn't upload the WriteNetworkSettings NetEEPROM example over Serial once Ariadne has been installed but that shouldn't be a problem, it would only require adding some documentation of how to accomplish it.

@loathingKernel
Thanks! Thats excat what i needed! 👍
an offtopic-question: i want to change the LED-Port to Digital-7. Where can i change this?

You can change that in spi.h. There you will find the pin definitions for all the supported boards and you can change it accordingly.
@per1234
Simply commenting out serialPoll, will give you a rough idea of what the size of the bootloader without serial would be thanks to the linker options. The --gc-sections as well as -flto strip unneeded binary code sections from the final binary at link time, so anything that is not used is not taking any space, among other things. The only reason I am a bit hesitant to actually add that to the makefile is that right now we have 9 different targets for each board+wiznet compination plus 1 for ethernet plus another 9 for debugging. Adding that, it would be another 9 targets with disabled serial. It is going to be a mess. so any ideas/suggestions/"Stelios, you are being stupid, just add it, it is not a problem", is going to be helpful.

I was able to find a few other lines of code(per1234@0a24076) to disable to get the size smaller but there might be more I didn't find. ariadne_atmega328_w5100_noserial.hex and ariadne_atmega328_ethernet_noserial.hex are close to fitting in 2 KB but I'm not sure how difficult it would be to free up that space. I was able to accomplish it by removing the code to write the version to EEPROM.
Freeing up 2 KB of flash on the ATmega328P based boards could be a very big improvement for some people, especially since the type of code running on projects that use Ariadne is likely to be pretty large. Barely squeezing into the section could be limiting to adding new features to Ariadne though.
I definitely do see your point LoathingKernel about adding more options greatly increasing the amount of work required to test and support this project. My fork has even more custom menus, etc. so I've experienced this first hand. I'm willing to take responsibility for some of the testing. I guess there are two different approaches that can be taken:
- Offering a more limited yet thoroughly tested product
- Providing many options, some of which may not be fully tested and relying on the users to report any bugs that may slip by.
I think the second option is perfectly valid in this sort of a volunteer-run free open source project as long as there is a reasonable attempt to make sure the most commonly used configurations are functional.
My personal preference is that Ariadne have as many features as possible without causing significant bloat. I never use serial uploads on my devices that run Ariadne so I think this feature would be useful as a custom Tools menu option in the IDE.

Quick reply:
Add the following declaration in main.c
int main(void) __attribute__ ((OS_main)) __attribute__ ((section (".init9")));
in the place of the previously commented out main declaration and magic will happen.

So now, at least for the atmega328 without the serial and everything else as it is, my version fits in 2KB space, even though just barely, and as I can see, so does yours. Yours is 2 bytes less, but that might some commented variable or something.
There are many small optimizations that can be done all over the code, and I believe we can gain enough space with refactoring to add some nifty features if we really need them even in the 2KB version.
