安装 SDK下载 SDK 在网盘“2.3_系统_Linux-4.1.15/03_工具”目录中下载 SDK 包文件。
- MY-IMX6-EK140、MY-IMX-EK40P：
fsl-imx-fb-glibc-x86_64-meta-toolchain-qt5-cortexa7hf-neon-toolchain-4.1.15-2.1.0.sh
- MY-IMX6-EK200、MY-IMX-EK314、MY-IMX-EK336：
fsl-imx-fb-glibc-x86_64-meta-toolchain-qt5-cortexa9hf-neon-toolchain-4.1.15-2.1.0.sh
准备安装- 把下载的包文件复制到编译主机中。
- 修改预安装目录的权限
$ chmod 777 /opt -R

QEglFSVivIntegration will set environment variable FB_MULTI_BUFFER=2 to enable double buffering and vsync.
If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1
Unable to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
