Unable to compile uinput module on cRIO 9030

[BradM]

=== Kernel Issue ===

When updating the kernel, and needing NI drivers, make sure to follow the instructions here: https://github.com/ni/nilrt/blob/nilrt/15.0/KERNEL_SOURCE.txt, starting at line 90. Basically, you need to make sure to put the needed modules in the correct place, the correct headers are going to be used for re-versioning the NI drivers, and that the cached version string of the kernel is not used.

=== MAX Issue ===

As far as why the target would not be accessible from MAX, can you check the processes that are running by running the command ps and looking for the NISystemWebserver processes (there are a different ones that should be up and running for various different services, including what is required for MAX communication).

Concerning the kernel,

The kernel now is 3.10.31-ltsi-rt29

and it used to be (after format etc) 3.10.31-ltsi-rt29-2.10.0f0

Could that be a problem?

Update;

After building kernel again => same error, in NI MAX, the cvs doesn't show.

After doing updateNIDrivers (in /usr/local/natinst/nikal/bin) it works, the CVS is visible again in MAX and I can deploy labview VI's...

so a general rule should be that after rebuiling the kernel, the ni drivers should be updated aswell with the updateNIDrivers

(before that, start installerUtility.sh aswell)

BradM, thanks for your support.
You have been helping me a lot on this!

[m-power]

Hi to all and sorry for the delay in answer.

I had some problems to clone the git file of linux rt. I directly downloaded the zip file from github.

After installing the eGalax driver, the monitor touch works properly!!!

Great results and thanks a lot to BradM for the procedure to compile the kernel.

By sumamrizing:

eGalax touch screen needs uinput, evdev, hid-moultitouch and HIDRAW kernel module. Once compiled on the kernel as suggested by BradM, the monitor touch works correctly.

Thank you all again

Marco

[BradM]

Great to hear, m-power

The main issue is that we haven't really tetsed on too many touch monitors other than consumer-grade and NI's own offerings, and ironed out the issues that we found along those lines. Be sure to comment on Touchscreen Usage Discussion

[Reji.V]

I'm using Palas 150PCUM touch screen monitor. I got an error while installing driver. uinput not found. So i tried according to the steps mentioned in "Adding Kernel Modules to NI Real Time Linux".But I am getting error while running the Makefile. Please help me out with this.

Error-   make: *** No targets specified and no makefile found. Stop

[m-power]

Hi Reji,

I solved as described in post #4 of this discussion.

Regards

[BradM]

Reji.V

Before you try installing a driver that, from what I've been able to find, indicates that it is only supported on 2.4 and 2.6 kernels, can you post the details of what the lsusb -v returns? If it's not a USB-connected touchscreen, let us know how the touchscreen input portion connects to the target.

[Reji.V]

Hi,

  I tried the same. But I got error.I have attached the error image. I have downloaded the kernel driver. I copied the Makefile in /drivers/input/misc. Many commands are not found.

[Reji.V]

Hi BradM

           The Touchscreen driver supports for kernel 3.x.My touchscreen monitor is USB-connected. I tried the command Isusb -v. It says "Isusb: command not found".
