$ bitbake fsl-image-x11 -c populate-sdk
- Please change working directory to where installer located and perform the following command.
$ sudo ./poky-eglibc-x86_64-fsl-image-x11-cortexa9hf-vfp-neon-toolchain-qt4-1.5.3.sh
Qt5 SDK
- Please perform following command to make toolchain installer.
$ bitbake fsl-image-x11-qt5 -c populate-sdk
- Please change working directory to where installer located and perform the following command.
$ sudo ./poky-eglibc-x86_64-fsl-image-x11-qt5-cortexa9hf-vfp-neon-toolchain-1.5.3.sh
