Serial console freezes and the program enters Hardfault handler.https://devzone.nordicsemi.com/f/nordic-q-a/32908/serial-console-freezes-and-the-program-enters-hardfault-handlerHello, I have interfaced MPU accelerometer on i2c and GPS on UART. Have enabled UART and using printf to display both sensor data. To begin with, both work fine individually. On clubbing them together, the console hangs after 15secs approx.
