Mode Power LED Status LED
Normal mode The power LED is on when
power is applied to the board.
Activity indicator, the LED flashes
when any communication
happens to the EDBG.
Bootloader mode (idle) The power LED and the status LED blink simultaneously.
Bootloader mode (firmware
upgrade)
The power LED and the status LED blink in an alternating pattern.
For additional information on the EDBG, see the EDBG User Guide.
