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.
