Wow ... the gcs run much faster now.
The big problem not is GCS but DATALINK.
Its kill 50% or more of CPU.

Hi Eduardo,

I haven't looked at CPU load... while it is not super fast, and resizing, etc. is slow, it's sort of usable without overclock...

You can also build the native (instead of the bytecode) version of the GCS and server, which should run a bit faster:

make ground_segment.opt

Then run sw/ground_segment/cockpit/gcs.opt instead of sw/ground_segment/cockpit/gcs

But IMHO running the GCS on the Pi doesn't make that much sense anyways... that was more to just see if it works properly.

Since you probably don't have a Display connected to the Pi, you need to ssh into it with X forwarding, and might as well just run the GCS on your laptop.

It's probably more interesting to just run link/server and maybe stuff like antenna tracker, ADSB on the Pi and then connect to the IVY bus on it via wifi/3g/internet from your laptop/home...

Cheers, Felix

Only to confirm.
Any one can tell me if raspi GCS get 100% processor full time ?

To get e reasonable response i need to use 900mhz overclock.
I think the new beagle board black will run much faster.

Running nicely on my Pi with raspian/hardfloat now, please let me know if it works for you as well.

Cheers, Felix

Hi Eduardo,

What kind of serial to usb converter is it? Also, does it work just running it into a raw terminal (without the Link agent)?

I have never actually run a real aircraft on the RasPi, only simulation...

Thanks,
