Firmware update (Linux)

First install dfu-programmer:

$ sudo apt-get update
$ sudo apt-get install dfu-programmer
$ which dfu-programmer

The last command will tell you where dfu-programmer was installed:

/usr/bin/dfu-programmer

You can check which version of dfu-programmer was installed using this command:

$ /usr/bin/dfu-programmer --version

The output should look like this:

dfu-programmer 0.6.1

Next, we'll get the Mac update package from the FlySight website:

$ wget 'http://flysight.ca/fw/flysight-update-mac-20170405.zip'
$ unzip flysight-update-mac-20170405.zip -d firmware

Then we use dfu-programmer to write this firmware to the FlySight:

$ cd firmware/flysight-update-mac/
$ sudo /usr/bin/dfu-programmer at90usb646 erase
$ sudo /usr/bin/dfu-programmer at90usb646 flash ./flysight.hex

The output should look something like this:

Validating...
40442 bytes used (70.53%)

Now we need to copy the new audio and configuration files onto the FlySight.

$ sudo rsync --dry-run -iva --progress --stats --no-o --no-g --no-p audio/ /path/to/device/audio/

Check the output of this command, then run it again without the --dry-run flag.

$ sudo rsync --dry-run -iva --progress --stats --no-o --no-g --no-p CONFIG.TXT /path/to/device/CONFIG_DEFAULT_v20170405.TXT

Once again, check the output, then run the command again without the --dry-run flag.

Finally, we can check what has been updated in the new configuration file:

$ cd /path/to/device/
$ diff -w CONFIG.TXT CONFIG_DEFAULT_v20170405.TXT

The old configuration file can be updated manually to incorporate any new features.
