Firmware and SD Card LED Status Lights
Additional LED status indicators are active when loading firmware or inserting a SD card.
For the operations described below, retries are provided, it may be OK if there are a few failed attempts. But a
continuous error indication means failed operation. When the maximum number of retries is reached, the Bootloader
will reboot.
A single flash of all LEDs simultaneously means a system reboot and the Bootloader is initialized.
GREEN - Fast blinking of the Power LED occurs when the SD card is inserted but the File System is not
mounted.
▪
If a SD card could not be mounted after insertion or if the card does not have the proper formatting
(FAT32) the Power LED will continue to fast blink.
▪
In the case of a valid SD card, the Power LEDs will fast blink for a couple of seconds while the File
System is mounting, then will resume normal blinking.
RED - Each flash indicates a failed attempt to initialize the SD card. This means the SD card is not inserted or it
is corrupted.
BLUE - This blinking of this light means the Bootloader is working properly.
▪
If the blue LED is blinking along with any other LED, this indicates the retry logic (see note below) when
initializing the SD card, mounting the File System and opening the Firmware file to update the NVM
memory.
▪
If only the blue LED is blinking, each flash indicates the next 20KB from the Firmware file was stored to
Non Volatile Memory (NVM).
YELLOW #1 - Each flash indicates a failed attempt to perform an operation with the File System on the SD. This
may mean the Bootloader cannot find Firmware or Backup file on the microSD, but it can also mean any File
System corruption.
YELLOW #2 - Each flash indicates a failed attempt to perform an operation with the NVM when storing
Firmware blocks.
