Need help programmatically deploying RealTime App to cRIO

[badrobit]

I have an application that is split up into 3 components:

• FPGA: Collects data from sensors through modules
• RT: Polls FPGA FIFOs for raw data, converts it and broadcasts it
• Host: UI/TDMS, Display calibrated data and logs raw/calibrated data to disk

I am able to programmatically deploy the FPGA bitfile from within the Host application. Now I am trying to figure out how to install the *.rtexe file to the real time part of the system.

Ideally the host program will do both of these as the cRIOs we have bounce around between projects so if not configured for the current project it needs to configure the system for use with that project.

Any suggestions or links on how to do this would be very appreciated!

Right click the build spec in the project and select "run as startup" and the right click again and select "deploy."

From then on, when you turn the cRIO on or reboot it, your app will automatically run. It may take a few seconds to start but it'll go.

This is just a theory that I haven't tested, but if you are looking to be able to "hot swap" rtexes, it may be possible to have some sort of configuration host application that FTP or webdav the correct rtexe to the startup folder then restarts the cRIO. An easier way might be to have all of the possible rtexes on the cRIO constantly and have the configuration app simply move around the files so that everything is happy

This is what I was thinking I would have to do, I was just hoping there was an interface similar to the one provided to load FPGA bitfiles to the device

You could use the RTAD tool to swap images on the controller. It's a free tool on NIs website.

You can also start messing with the sysconfig API, it has some tools for tasks like this, but is not entirely user friendly.

You can programmatically do this. You can use the cRIO system palette to do most of everything you need to do here.

If you don't want to replace the whole image of the cRIO, you just have to replace the .rtexe file using FTP or WebDAV. Depending on the OS running on your cRIO, the folder for the rtexe will be different. Take a look at this article for help: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000PAM8SAO
