New Note: The bootloader in OpenLog was changed in March. This video only applies to OpenLog devices made before March 2012. If your OpenLog came from Sparkfun with a version 3.11 or later fimrware (i.e. not 2.x), then it was made after March and this video does not apply. OpenLogs made after March 2012, are designed to be updated directly from the Arudino 1.x Interactive Development Environment.
This video is only recommended viewing for those people that are actually going to perform an upgrade of the 2.x firmware in their OpenLog, and would like a demonstration of the process.
For users of MAVlink with MatrixPilot there are 3 benefits to upgrading from a 2.x firmware to a 3.11 binary safe firmware:
1. Making the OpenLog binary safe for MAVLink. (The ability to set zero escape characters, meaning None)
2. Improving the Baud Rate reception at 57600 (Removing a bug specific to 57600 baud in the 2.x firmware)
3. Imroving the general speed at which the OpenLog can receive characters (More proc time for writing to SDRAM)
