The state tables below are used to decode the system status and activity. The first table is for the Bootloader followed by the Application state table.
All CoreOS devices have both a Status and Activity indicator. In some cases the indicators use a single RGB LED or a separate blue LED
and an RGB LED. The indicators are used to communicate system status and error information:
1. Some CoreOS devices use a non-removable flash memory device instead of a micro-SD card.
2. For a single shared RGB LED a blue flash will override the current color.
