Firmware Installation/Update
The newest firmware is already installed on the DRS when it is shipped to the customer. If you
want to update it, you need the new FW which is a file with the extension ".bin" provided by
Drone Rescue Systems GmbH. Simply store this file in the root directory of the micro SD card
to perform a firmware update. When the DRS powers up, the file will be found and the update
process starts automatically. The status LED indicates the
process which takes about 5 to 10 seconds. After a successful update the LED blinks green for
a few seconds, the ".bin"-file is deleted, and the new firmware is started. In case of any error
the LED blinks red for a few seconds and the old firmware is started. Observe the LED carefully
to see if the update was successful. A file named "bootloader.txt" is written to the SD card in
any case. It contains information about the update process, especially about the success. Also
check this file to see if the update was successful. You can delete it afterwards.
