Quick & dirty tool to update FNB58's firmware on Linux. Original tool works under wine, but that's a simpler alternative if you just want to update and get it over.
Building on Linux or MacOS are the same by running the make command.
The makefile automatically detects the OS and runs the right build command and installs hidapi from brew if missing.
Note: Only tested it on MacOS 15. Other versions are not guaranteed.
As the hidapi library is a dependency it needs to be installed. The make script should automatically install it from brew on MacOS. On Linux you have to install it manually.
Plug your device to your computer's USB port while pressing 'select' button (navigation wheel). You should see splash screen indicating that you're in DFU mode.
On Linux you might need to add the following udev rule to make sure you have access to the device:
KERNEL=="hidraw*", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="0038", GROUP="uucp", MODE="0660"
Alternatively, you can run the tool as root.
Then, simply run the tool:
./fnirsi-dfu-update Fnb58V0.68.ufn
And wait till it's done.
