OK I have managed to debork the Quad… well sort of!
I discovered that the selectors marked <…> is a three way button… Left, right and it has a push down function as well. Holding it down while starting the device puts the quad into USB only… Happy days I can access my usb drive.
I then managed to reinstall the 0118 fpga and sys files.
I still got the error message when trying to install the app file.
Out of desperation, formatted the USB disk via windows and tried again. This time the APP file installed.
I have a functioning device again but with one problem…
Each time I start it it asks for an Enhance Licence. I can skip past this, but it tells me I am going into Enhance Version Demo with a decreasing count it started at 250. Guess that I am going to loose some function of the quad at some point unless I can get hold of the licence code.
On reflection, when it was borked, it did say “basic hardware version” I did not think anything of it at the time, but checking back to video I took of the device it was supplied saying enhance hardware version on the splash screen.
Ok. Guessing game here.
on the usb drive there is possibly a key file that somehow got corrupted when I was updating the firmware. In it is holds a registration key that allows access to some of the software features. (guess is that this is not as opensource as we might think)
By formatting the drive presumably I have removed the corrupted hidden file but at the same time have now limited the function of the device. When my countdown reaches 0 on the Enhance Demo I will no doubt find out.
So Seeed, how do I go about getting my licence key?
