Is there a way to get the sbRIO to boot faster?

[Philbot]

I'm using the Robotics Starter Kit (with the sbRIO 6931) and I've built and deployed the Roaming example.

From a cold reboot, it takes 63 seconds before the program starts running.

This seems too long for a High Performance Realtime system. 

The cRIO application we use for our FRC robots boot much faster than this.

I dumped the serial debug log and found that everything up to (and including) "NI-VISA Server 5.0 started successfully."  takes 23 seconds, but then "Welcome to LabVIEW Real-Time 10.0" takes another 40 seconds.

Any way to speed this transition up?

Here is the full boot log.

Hi Philbot,

See here.

Thanks and have a great day.

Hi Esmail

I checked out that link, but there's not a lot to go on.

I'm already using a Static IP, so that's not the problem.  The boot blasts right past that step.

Beyond that, I'm not sure what "uninstall any software that you don't really need from MAX and disable services you don't want from the project" means.

Why would there be any "services" in the project that I don't need?  

I don't see any provisions to remove them in the Project Build specification.

All unused VI's are already excluded.

If I eliminate stuff from MAX (assuming I know what to eliminate, and how to do it) wouldn't that remove it from all my projects?

My problem is that I have the Academic License installed, so essentially "Everything" is on this machine.

I need to ensure that any changes I make won't effect other projects.

Since I'm working with the vanilla "Roaming" application that comes with the Robotics Starter Kit, can you give me ONE example of something I can remove to make it boot faster.

If I can work through that item, then I can probably figure out other things I can also remove.

I just need a starting point.

Thanks

Phil.

Hi Phil ,

I am sorry about the late response, but we had to escalate this to R&D and get you some information about this example. The Roaming example, while sounds like a simple application, has a lot of things going on in the code and we load a lot of dependencies with the example. Because of these dependencies, it will take a while for the code to load and we wouldn't suggest removing any of it if you would like to use the example. Also, regarding the FRC cRIO booting faster since it has a faster processor. If you compare the sbRIO to the FRC cRIO, the FRC cRIO has a 400MHz processor while the sbRIO has only 266MHz. So it would be expected that the sbRIO would take a longer to boot.

Hope this information helps!

Thanks and have a great day.
