mangopi_r3 Qt5问题

buildroot里想要增加Qt5的支持,于是make menuconfig->Target packages->Graphic libraries and applications(graphic/text)里勾选Qt5然后进入Qt5里勾选gui module和widgets module。其他不变,编译通过,下载到板子出问题。log如下

没勾选之前是可以的,我
make clean
make widora_mangopi_r3_defconfig
重新生成.config
再编译下载都正常

Re: mangopi_r3 Qt5问题

那应该是 rootfs超过mtd2大小了, 你改一下 board/widora 目录下面的关于nnad的配置文件

我对比了下,加Qt和没加Qt的结果,差别应该就是没加Qt前编译出来的rootfs.squashfs大小是5.71M,加了Qt后rootfs.squashfs大小是12.2M
我看下载脚本里@REM %SELFPATH%\bin\dfu-util -a rom -D output\images\rootfs.squashfs这句话,虽然屏蔽了,但是意思是rom应该就是写入rootfs.squashfs这个文件的内容,然后我看/board/widora/mangopi/r3/devicetree/linux/devicetree.dts下的nand flash描述
partition@2 {
    label = "rom";
    reg = <0x600000 0x4000000>;
    read-only;
};
大小0x4000000就是64M。够的啊,那为啥不行呢
