The wiki http://dev.ardupilot.com/wiki/building-for-bebop-on-linux/ specifies that a “new firmware” has to be installed on the Bebop, for ardupilot.
Where do I find information about it? specifically:
what [color=#FF0000]version [/color]is that kernel?
where is the linux [color=#FF0000]source [/color]+ kernel config file?
which [color=#FF0000]compiler [/color]to use?
will that “firmware upgrade” clear all [color=#FF0000]filesystems [/color]on the Bebop?
(or just replace the kernel, leaving the filesystem unmodified)
Can I upgrade the firmware and use Bebop as before?
Can I revert back to Bebop firmware? how?
