Using the DAB
LED Status indicator
The DAB has a dual color surface mount LED mounted near the board edge near the FLASH card connector.
If the FLASH card is present upon power up, the dual color LED on the DAB should briefly illuminate green as the FAT file system code initializes its internal variables.
If the FLASH card is removed, both LED’s will illuminate and provide a yellowish glow to indicate the absence of the card.
When the FLASH card is present, if the LED glows solid Red, with brief flashes of Green, this indicates that the FLASH media is not correctly formatted.
In normal operation, the Green LED will flicker when the FLASH card is being accessed for reading, and the Red LED will flicker when the FLASH card is being accessed for writing.
