PowerFLARM Core Manual v.150 International
• Butterfly display firmware update
• Flight record readout
USB sticks should:
• be formatted with FAT (FAT16 or FAT32) file system (NTFS or
exFAT will not work)
• have capacity <= 32GB
• Be of USB 2.0 type (not USB 3.0; USB 3.0 connectors are typical-
ly blue on the inside).
Suggestions for USB stick usage:
• Use a dedicated USB stick for your PowerFLARM device(s) (Ex-
ception: Updates of multiple devices to the same software
and/or obstacle DB).
• Leave flight logs (IGC files) on your USB stick during the flying
season. This will reduce the time needed for readout, because
files already on the stick are skipped.
• Sort IGC files by date on your PC. The last file in the list then
corresponds to the most recent flight.
• If multiple firmware update files are on the USB stick, Power-
FLARM will chose the most recent one.
• Do not keep multiple obstacle database updates on your USB
stick.
• PowerFLARM will skip firmware, license and obstacle database
updates which are already installed.
Status LED indications
The Status LED can show three different colors: GREEN, ORANGE
and RED.
Please note that ORANGE may appear similar to RED. The color
during the first few seconds after startup is ORANGE.
The meaning of the Status LED indications is as follows:
• GREEN: Core operates normally
• ORANGE during start-up sequence: May take up to 20s
