Hi everyone,

Can someone explain me what this flag in Makefile examples do ?

I just finished an app for a custom board. As my Makefile was based on an example, there was still this flag present. As its comment suggests, it's for development so I decided to remove it.

After removing it, my application starts normally right after flashing my board but as soon as I unplug it from power supply and plug it again, the app doesn't start anymore. I flashed the app on a Nucleo-F303RE to get some console output but I just get garbage from pyterm. I decided to keep this flag as it works flawlessly with it and takes only 4kB more in ROM but it could be great if someone knows a little more about it.

What could cause my app on two boards to fail starting without this flag ? In my app, I use some DEBUG() macros, I start two threads, do some UDP packets exchanges with another boards and that's it.

Best regards

Joel
