Problems disabling safe mode. #162

Boards version: latest (i will add the version number later), Arduino version: 1.8.19, Operating system: windows 10,

Hello, i am having trouble disabling safe mode in this software package, my sketch doesn’t want to fit, and it’s not even that big (it is a little but i thought it would fit). According to the description in the core_settings h file, if i disable it, it will give me more flash space, and i can see that the flash usage seems to ramp up quickly, even for a small code.

Unfortunately disabling safe mode has the opposite effect, taking up 2 single bytes of flash instead of giving me a bunch more free space. I tried commenting out the define for it, i tried defining DISABLE_SAFEMODE (i think i have it right) in my main sketch like i saw where it says ifndef in core_settings, i can’t disable it correctly.

Is this a bug in the most recent release? Thank you for any help you can give me.

Can you post your sketch? There may be other things you can do to optimize your code to make it fit.

I'll look into why the sketch size increases.

I will post my sketch in a gist when possible. I was using the standard arduino functions, so maybe that’s contributing?

I could always try avr c code like shown in some of the examples, which will require me to make some of the gpio functions myself. I personally prefer the native arduino functions though.

Do you know of another way i can disable safe mode to get more flash space?
