Boot code LEDS
The boot code LEDs are active when the TX 4000 board is powered up. These LEDs
progress through a series of red codes. If the power up is successful, these LEDs
turn green.
If no LEDs illuminate, the voltage levels may be too low, or the power supply may
not be providing enough 3.3 V or 5 V of current to power up the TX 4000 board.
