Qt5 target image location

How to set up Qt Creator to cross compile for embedded Linux
I believe having safely built a Qt5 target image based on 2.6.1 Openembedded.
I also followed advice from :
Help needed to get Qt5 app on Colibri Dev Board 3.1A

Change the “build/conf/local.conf” file to add the required packages:

PREFERRED_PROVIDER_psplash-support = "psplash-angstrom"
 +IMAGE_INSTALL_append = " qtbase qtbase-fonts qtbase-plugins cinematicexperience"

and then build the angstrom-lxde-image.

 MACHINE=colibri-t20 bitbake angstrom-lxde-image

This would give an angstrom-lxde image with Qt5 and X11. But where such “image” is located ? It is something like a File System that can be sent to EVM target by means of NFS ? A new kernel is also required , to be transferred to target ex by means of FTP ? I understood that once such new target will be available, it was the target to be interfaced to a PC running qtcreator, isn’t it ?

Thank you for your attention.


The new image should be located at ‘OE_ROOT/deploy/images/colibri-t20’ if there is no error from OpenEmbedded, its name is similar with ‘Colibri_T20_LinuxImageV2.6.1_20160929.tar.bz2’. You can use a SD card to flash Colibri T20, see this. This new image include some Qt5 libraries, you can find them at /usr/lib/libQt5* on target.

Thanks for your fast support.
What if I simply expand Colibri_T20…tar.bz2 and mount rootfs directory on NFS ?
The kernel also must be updated ? Where can I find it ?
Thank you in advance.


Sure, NFS will work. Find more information about setting that up here. The kernel you find in the colibri-t20_bin folder inside that same tar.bz2 archive.
