Serial println crashes using Serial print("...\n") does not

[xRadx]

Just what I noticed - using Serial.println very often causes program to hang, but when at the same place I use Serial.print("...\n") the code runs w/o any problem...

Not sure what might be the problem, but it seems that the implementation of Serial println causes a problem.

Could you be more precise? board used ? Is USB Serial enabled and supersed U(S)ART?....

The board is Nucleo F746ZG. I am using default config for Serial. I have quite much expirience with Arduino IDE for AVRs, but I am just starting with stm32duino.

Seems you open several discussion and your setup is not very clear. Are you used FreeRTOS here too?
Sketch example? ....
