QTCreator together with SABRE Board for the i.mx 6SoloX

[christophbismar]

Hello everybody,

I'm currently trying to set up QTCreator in Order to work with my SABRE Board for the i.mx 6Solox. I've managed to get QTCreator to communicate with the board (after setting the IP-Adress up, you can Test the connection and that seemed to work), however, I cannot deploy a program (one of the examples.

Does anybody else here work with this combination and has a tip for me how to do that? I suppose I would have to create a new core-image that includes QT5 and the other capabilities I need (USB-host Stack and the likes)?

Right now, the demo image is running on this board: Poky (Yocto Project Reference Distro) 1.6.2.

Any help would be greatly appreciated since I'm pretty new to this topic.

Regards,

Christoph

Hello,

If you use the latest BSP for the i.MX6SX:

http://www.freescale.com/webapp/Download?colCode=L3.10.53_1.1.0_LINUX_DOCS&Parent_nodeId=13376994810...

Edit conf/local.conf and add:

EXTRA_IMAGE_FEATURES = "debug-tweaks tools-debug eclipse-debug ssh-server-openssh"

CORE_IMAGE_EXTRA_INSTALL += "openssh-sftp openssh-sftp-server"

Follow the user guide to build "fsl-image-qt5”. Then , create and install the SDK "bitbake meta-toolchain-qt5”.

Then, you can configure the toolchain and the target device for debugging.

Check this doc:

Hello Luis,

thank you very much for your quick reply. I'm having trouble bitbaking the layer "fsl-image-qt5", bitbake says "Nothing PROVIDES 'fsl-image-qt5'". How can I obtain a local copy of this layer? Do I even need to do that?

Sorry for all these noobish questions.

Regards,

Christoph

EDIT: With the help of this tutorial: Communication between asymmetric cores on i.MX6SoloX I've been able to setup my Ubuntu correctly and am now compiling fsl-image-qt5. Let's see where this leads.

EDIT2: For all the people facing the same problem as I was: Install and setup your SDK like in the linked tutorial. After that go to /usr/bin/ and use "sudo gedit qtcreator.sh" There you need to paste after "export LD_LIBRARY_PATH":

To run QTCreator, you then have to type: "sudo sh qtcreator.sh". The Super User rights are needed for correct compiling, why is beyond me. Otherwise QTCreator would always throw the error in the likes that "c is an unknown command" because he tries to use a parameter as a command.

I used up a good 6 hours to find this out, I hope, somebody reads this and can solve their problem a little bit quicker.

The SDK was installed in the standard directory, don't know if this is actually needed or not, but I tried this in the process of trying to get it all to work aswell and haven't tried using another SDK location but with QT sudo-mode.

Anyway, have fun with this solution.

Christoph

Hi Christoph,

If you add :

source /opt/poky/1.xxxx/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi

in the qtcreator.sh , you don't need add the lines you added and you don't need execute with sudo as is explained here:

https://community.freescale.com/docs/DOC-95251

Hello Luis,

I tried your way and it did not work. I always get permission denied error, if I don't run with sudo. If I run your version (with the one line) as sudo I get a compile-error again.

I'll just stick with the ugly big qtcreator.sh that works.

Thanks anyway.

Regards,

Christoph
