* logic on the board and are not available for software control:
*
* LD1 COM: LD1 default status is red. LD1 turns to green to indicate that
* communications are in progress between the PC and the
* ST-LINK/V2-1.
* LD3 PWR: red LED indicates that the board is powered.
*
* And one can be controlled by software:
*
* User LD2: green LED is a user LED connected to the I/O PA5 of the
* STM32F334R8.
*
* If CONFIG_ARCH_LEDS is not defined, then the user can control the LED in
