My Udoo Bolt has a constantly flashing LED. It is very annoying I found out that it is the Arduino LED. On page 60 of the manual it says that the LED behavior can be influenced by programming the microcontroller. Is there an easier way to disable this LED?
The default (came with the factory pre-programmed) Arduino program loaded is called "blinker" (blink every one second.) You can overwrite with an Arduino program (modify the sameple "Blinker" program), using Arduino IDE, to replace the default behavior.
