Question

硬件：Riotboard，imx6solo;

BSP ：fsl-community-bsp，jethro branch;

Meta-Qt5图层：jethro分支;

“ bitbake fsl-image-multimedia-full ”生成的图片;

“ bitbake meta-toolchain-qt5 ”生成的工具链;

参考指南“在Wandboard上使用yocto构建Qt5 - Wandboard Wiki”;

qtbase-plugs包存在，libqeglfs.so也存在;

设置

Qtcreator：设备，套件，编译器，调试器，rootfs，ssh连接;

注意：我只更改了主板上的rootfs，内核，uboot，dtb文件仍然使用了embest。内核为3.10.17_1.0.0;这会影响问题吗？

现在只有一个问题：当我运行“./helloworld -platform eglfs”时，出现错误“无法打开egl显示。已中止”。我试图导出FB_MULTI_BUFFER = 2， export DISPLAY =：0.0，export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER = 1，错误仍然存在。我也尝试了fbset，将深度修改为32bit，无法解决问题。

我的另一个帖子链接：How to enable eglfs plugin in Yocto setup? using yocto+meta-qt5 for Riotboard

我的最终目标是为定制板（类似于Riotboard）开发Qt5个应用程序，此外还有其他C应用程序也在板上运行。对于实时功能，我还将包含Xenomai，因此该项目将包含许多内容。

Answer 1

这就是我用于EGLFS的内容：

var obj = {
           _time : "",
           get time () {
             this._time = new Date();
             return this._time;
           },
           set time(val) {
             this._time = val;
           }
};

document.write("<pre>" + obj.time + "</pre>");

另外，你不需要这些;

PACKAGECONFIG_append_pn-qtmultimedia = " gstreamer010"

PACKAGECONFIG_append_pn-qtbase = " sql-sqlite \
gst-plugins-base \
accessibility \
pulseaudio \
examples \
"
EXTRA_IMAGE_FEATURES = " ssh-server-openssh package-management \
             tools-sdk tools-debug"

Answer 2

最后我解决了这个问题，我切换到了yocto和meta-qt5层的Dizzy分支。通过这种方式，它匹配embest提供的内核版本。

“无法打开egl显示。已中止”使用fsl-community-bsp + meta-qt5
