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

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

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

楼主你好，看到你uboot启动信息是从spi nand启动的，最近我在搞这个spi nand启动，想参考一下代码。你用的uboot是哪个仓库的代码？还有烧录工具？
