Hello, my code is freezing on very simple code. For debugging purposes I use serial.println() String number = "5"; Serial.println("starting conversion"); int stringNumber = number.toInt(); Serial.println("conversion done"); When i execute this, it gets stuck at the .toInt() function Also, when I try to divide a long : long duration = 2000; Serial.println("division start"); long result = duration / 25; Serial.println("division end"); Same problem occurs, the code just seems to stop there , it never gets to "division end". Anyone got any insight on why code is bugging with these common operations? My code is working fine on some arduino uno board, but it won't work on the embeded board on the udoo. thanks a lot !
