Unable to compile uinput module on cRIO 9030

[Biebel]

Hi guys,

Has this been solved yet?
I ran into the same problem.
I've also an eGalax touchpanel wich I want to use with  my CVS-1458RT

same behaviour: mouse movement works like a charm, but can only click once.. and then the clicking event does not work anymore.

A solution would be that I use the windows version for the CVS but that's my last option..

Can you try an experiment?

Copy the attached '05-egalax-virtual.conf' file on the target in '/usr/share/X11/xorg.conf.d'. You will have to do this as 'admin' (i.e. 'lvuser' doesn't have permissions to write at that location). Reboot the target and let us know if there are any changes in the way the touchscreen reacts.

Also post the following log file (after you reboot): /var/log/Xorg.0.log

The output from running 'lsusb -vvv' on the target would also be helpful. You will have to install 'usbutils' to get the command. You can do it by running 'opkg update' followed by 'opkg install usbutils'

[Biebel]

Still the same behaviour with when I put this file into the '/usr/share/X11/xorg.conf.d folder

IN annex the Xorg.0.log

I'll try the lsusb thing today..Regards,

Bruno

Hi Gratian,

the same wrong behavor with the virtual conf file too..

attached the Xlog a lsusb log files.

regards

[m-power]

As I told before, the EV_TOUCH value of code 330 is always high on my touch screen. I.ve tried to force the value to be 0 after the touch tapping with the C code:

#include <stdio.h>

#include <stdlib.h>

#include <unistd.h>

#include <linux/input.h>

#include <fcntl.h>

#define MOUSEFILE "/dev/input/event7"

int main()

{

    int fd;

    struct input_event ie;

    if((fd = open(MOUSEFILE, O_RDWR)) == -1) {

        perror("opening device");

        exit(EXIT_FAILURE);

     }

ie.type = EV_KEY;

ie.code = 330;

ie.value = 0;

write(fd,&ie, sizeof(ie));

                    printf("write type %d\tcode %d\tvalue %d\n",

               ie.type, ie.code, ie.value);

}

    return 0;

}

Ufortunatelly, even if the value is resetted to 0, the monitor touch doesn't work. May be it depends by other driver.

I will try to add the HIDRAW module on the kernel as suggested by eGalax

Bye

[BradM]

Biebel,m-power,

In order to configure and build a kernel with the HIDRAW support that eGalax is calling for:

1. Enable ssh on your target and login
2. opkg update
3. opkg install git
4. opkg install ncurses-dev
5. opkg install bc
6. opkg install coreutils
7. opkg install --force-downgrade packagegroup-core-buildessential libz-dev
8. cd
9. git clone git://git.kernel.org/pub/scm/fs/squashfs/squashfs-tools.git
10. cd squashfs-tools/squashfs-tools
11. make && make install
12. cd
13. git clone git://github.com/ni/linux
14. git checkout nilrt/$RELEASE/$KERNEL_VER
    • For 2015, this will be nilrt/15.0/3.14
15. make nati_$TARGET_defconfig
    • E.g. for your vision targets, you'll use nati_x86_64_defconfig
16. make menuconfig
    • To enable HIDRAW, Device Drivers→HID suport→HID bus support→/dev/hidraw raw HID device support ('Y' to enable)
17. make ni-pkg
    • This will create a kernel, modules, and headers squashfs (needed for NI driver reinstallation)

Basically, you should have someone who's a bit more experienced working with Linux run through these steps, as I don't really have a x64 target to test this out on and there may be missing steps or steps that need to be adjusted.

This may seem like quite a bit of pain/annoyance, but keep in mind that touch panels with the eGalax touch controller were never tested nor suggested that they would be supported. This is the reason that NI resold touch panel displays with many mounting options and thoroghly tested those. There are simply too many options out there and Linux touch screen support is fairly low on many of the touchscreen manufacture's list of concerns.

HI,

I was finally able to build the kernel with HIDRAW, uinput and evdev options enabled.

Now it created 3 folders:

-boot (with the bzImage in)

-headers

-lib

I know I need to be carefull now, and because I never replaced a kernel, I would appreciate it when you tell the next steps?

Thanks,

Bruno

[BradM]

Again, I don't have a x64 target in front of me, but the good news is that you can always force the target to boot into Safe Mode and reformat through MAX.

Pulling from recollection, the .../boot/bzImage will go to the /boot/runmode/, replacing the existing bzImage (you can optionally copy the existing to something like "bzImage.old")

The .../lib/ directory contains the modules/firmware for this recompilation of the kernel. Copy the content of this folder to your /lib directory (if you are in Run Mode/LVRT-mode currently)

The .../headers/ directory contains a headers.squashfs. Copy (and rename) this file to replace the existing kernel's header squashfs at /usr/local/natinst/tools/module-versioning-image.squashfs (again, you can rename the old to keep it around)

Once all of these have been done, reboot your target. When it comes back up, either check in MAX or run uname -a from a console to make sure that you're using the new kernel (check the date of the build, and note that it will match the time as set on your target, as that's where the kernel was built)

[Biebel]

ofcourse it failed booting.

Now I'm back on the old kernel (went through the faile safe mode etc)

I should start with a default configuration of national instruments I think, but I didn't find the nati_x86_64_defconfig file, only the x86_64_defconfig file...
