晕哥 说：请教版主 很多字显示不出来是为啥?比如 能 陀螺仪 等等 要设置啥字体?
陀螺仪用 label是能显示出来的，亲测能用，你应该是代码那里没有改好吧，晕哥发的字体生成工具还是挺香的
还是老老实实用buildroot吧，抱起晕哥嘬一口
是不是用了uClibc，要glibc才行的
额，解决了，是链接库出问题了，在 qmake.conf 文件中，在QMAKE_LINK 后加上 -latomic就好了，但是又出了新问题。。。。。，一部分log如下，是不是我的编译器有问题啊，哎

等会把文件buildroot_v3s_whycan.cn.tar.gz分享到 QQ群: 544762792, 约3.4G
晕哥，群咋进不去啊，答案总是不对 - -
是不是用 TIM, 这个软件有bug,用电脑qq或者手机qq
是的，哈哈哈，是说总进不去

晕哥 说：可能你又一个被官方文档毒害的孩纸: https://whycan.cn/t_2002.html#p13479
确实呀，把那冒号去掉就好了..现在就到 [ 1.436840] Waiting for root device /dev/mtdblock3...
这个了
https://whycan.cn/t_2179.html 参照这个大神的帖改
我今天也遇到了，除了更改跟MMC相关的东西外还有一个比较容易忽视的是“Fixed voltage regulator support”要选中。
Device Drivers ---> Voltage and Current Regulator Support ---> Fixed voltage regulator support；
Device Drivers ---> MMC/SD/SDIO card support ---> <*> HW reset support for eMMC
<*> Simple HW reset support for MMC
<*> MMC block device driver
(8) Number of minors per block device刘少来了 说：smartcar 说：https://whycan.cn/t_2002.html#p13479
改成 root=31:01 试一试
这么改不行，我觉得应该是官网给的文件系统有问题，或者说内核哪里没有配置好，再去看看;)
我之前出问题时这个已经配好了，我是参照 https://whycan.cn/t_2179.html 来改自己内核配置的，最后启动成功了
使用buildroot构建文件系统, mplayer视频播放器, Qt运行库等
1. VMWare建立新磁盘，创建一个干净清洁方便复制的环境。
https://whycan.cn/t_251.html2. 下载最新的buildroot稳定版本
https://buildroot.org/download.html
buildroot-2017.02.7.tar.gz3. 配置buildroot 参数, make menuconfig; make
如果不会配置， 就下载下面这个文件，然后把 buildroot-2017.08.1_LicheePi0_V3s.config 拷贝到 buidroot目录成 .config 文件。
buildroot-2017_08_1_LicheePi0_V3s_config.zip4. 执行编译, 生成文件跟文件系统。

晕哥，spi-flash 16M能塞得下qt吗，还是说至少32M
刘少来了 说：jiangming1399 说：按理说默认就是root用户才对啊，你构建jffs2的时候有没有用fakeroot?
没有，我用的官网提供的buildroot和 .config文件，然后自己做了修改，修改后里面也没有用到 fakeroot
我感觉可能是文件权限的问题。你用的是我的打包脚本吗？如果不是的话，在制作jffs2的时候要用root权限，或者用fakeroot，不然里面的文件权限可能会有问题。
哈哈哈哈哈，成功解决了，刚刚看了下楼主的脚本，和我的写的脚本有点不一样，发现mkfs.jffs2 -s 0x100 -e 0x10000 --pad=0xAF0000 -d rootfs/ -o jffs2.img 前面应该加上 fakeroot，打包后成功启动。
刘少来了 说：jiangming1399 说：USB那里没有启用gadget。要么把gadget打开，要么修改inittab把里面的/dev/ttyS0的getty给删了
开启了gadget后，启动log基本没变化，但是改了inittab后，启动log如下，还是卡住了 - -。感觉是root权限的问题，有没有什么方法，让开机启动时就是root
