USB-C monitor adapter compatible with cRIO-9045 (display port over USB-C)

Hi all!


I've been trying without success to make a 2 independent monitor setup work with our cRIO-9045 for a special project we are developing.

We need to have an extended display configuration on the cRIO over the USB-C port but so far we have only managed to make it work on mirror mode.


The custom linux distro NI uses on its embedded systems certainly doesn't make it easier for us to make the adapters we've bought so far work.


We tried these adapters ([1] and [2]) and even managed to install its driver through a very painful process messing with its makefile! But the cRIO, even though it is able to recognize that there's a second monitor on HDMI-1 (listed on xrandr just below DP-1), fails to provide a different image, and still mirrors it. The "Display" configuration still lists only one monitor


We are now targeting this Dell's D6000 USB-C dock station [3] but since we haven't even managed to install its Displaylink driver (which is readly available only for Ubuntu), we will not be wasting any more money until we find someone that had done it before in an effort to learn what they made differently.


I know that this a really open question but have anybody made such a setup work over USB-C on cRIO? If so, would you care to share with us how?

 

Thanks!

 

PS:

We know that there are some monitors out there that provide in addition of a "DP in" also a "DP out" connector so you can daisy-chain them, but they cost just shy of USD 2k here in Brazil, so they are not really an option for us...

Were you able to resolve this?
I have a similar requirement using NI cRIO

Furthermore I need both monitors to have touch screen functionality

Not yet.

We bought the Dell's D6000 but it only arrived today.

I'm going to try to make it work and if I manage to do so, I'll update this thread.
