MAVFUSE

My attempt at creating a FUSE3 filesystem over a MAVFTP connection. This makes it simple to transfer files to and from the SD card of a PX4 based drone without having to physically remove the SD card.

Supports basic file operations like read, write, open, close, etc.

Note that since I started work on this, a MAVFTP implementation with experimental FUSE module has beed added to pymavlink. As of writing, it only provides read support, and is unstable on my computer. However, with time, it will likely become the better option.

Installation

1. Install FUSE3 system libraries (Ubuntu/Debian: sudo apt install fuse3 libfuse3-dev)
2. Install the required python packages (pip install -r requirements.txt)

Usage

python3 -m mavfuse <connection_string> <mountpoint> [-w] [-d] [--list_crc32_xattr]

• -w enables write support
• -d Print debug information to the console.
• --list_crc32_xattr unless specified, the user.mavlink.crc32 xattr is hidden unless directly requested. This is because the checksum is computationally expensive for the FCU to calculate, and is not always needed. (NB! MAVFTP uses a non-standard CRC32 algorithm. See crc32.py)

E.g. python3 -m mavfuse tcp:127.0.0.1:14550 ~/mnt/mav
