6 BNA Bootloader

This chapter describes the functions of the BNA Bootloader software. Each BNA device is equipped with a Bootloader, which functions in the same way for all BNA device types.

Note : BNA Devices are not equipped with any application firmware. This must be loaded into the device prior to using it.

6.1Startup Behavior

After resetting or power-on the BNA device, all LEDs on the front will be switched on. Immediately after that, the BNA Bootloader starts working.

When the BNA Bootloader is active, the heartbeat LED on the BNA front panel flashes RED.

In contrast, any running application firmware indicates its execution with a GREEN flashing heartbeat LED.

The Flowchart depicted in Figure 6-1explains the BNA execution sequence. It is necessary that the user understand this in order to be able to react to or influence the behavior of the BNA device. Furthermore, it helps understanding in which state the device currently is while looking at the LEDs on the front panel of the BNA.
