@资本家大善人
请问你这是改了哪些东西吗，我下载的5.10.1的内核，menuconfig里配置了st7789v驱动就可以使用了。
@Expelliarmus
你目前除了换内存卡，还采用过什么手段来尝试解决这个问题？
我技术不太行，但是已知你内核加载了，同时文件系统也能够正确的启动一部分，否则系统的的服务那些是不可能正常加载，那些服务都是需要在文件系统中读取的。而你的错误是启动后出现的内存卡的什么地址问题，这个我也不懂，目前都是站在巨人的肩膀上跑起来的。
我说说我能想到的几个暂时的启动方法，来排除是哪里的问题。
1.题主描述换了sd卡，不知到换取的sd的牌子（目前我使用的三星，三星可用，还有某宝那些专用的sd卡也肯定可用）是否相同。
2.如果sd无误，是否有尝试更换内核或者其他的文件系统。
这两个控制一下变量尝试一下，是可以得出一个结果，试一下吧。。:D
这还是需要一个spi flash 来储存东西啊，能不能使用sdcard裸机呢。。。就是说应该要先加载个读mmc的驱动，再将sdcard内的东西搬到sram中运行？
@Expelliarmus
贴一个我自己编译的uboot,buildroot，减少了一些该芯片内核不需要的的东西的启动过程，内核是下载的linux kerne 官网的5.10.1，参照4.12和网上的资料的修改的，编译的工具链也更新到了750。我内存卡使用的是三星的，买了一个128g的，舍不得糟蹋，手里的32g被我拔插的不像样。。。你是使用的哪个uboot 和kernel及文件系统？看你那启动都有systcl了，看来不是像咱这光不溜秋的那种。内核版本前面的都没有贴全啊，应该直接把uboot都加载驱动文件系统这些一起贴上来，像我下面这样

@forever_rainy
你i2c连设备了吗？设备上的scl sda上拉了吗？
如果设备和zero都没上拉，那肯定不能正常工作。
需要一点时间测试，因为手里没有i2c设备，但是有个stm32f1的核心板，就暂时试试stm32 i2c slave，还要给引脚加上拉电阻，比较麻烦，感谢提示，自己着急了，静不了心下来去研究。
小熊猫 说：检查 I2C SCL/SDA 有无上拉
这个咋检查，是要看原理图，再自己增加电路，还是，能够使用软件上拉（这样按照以前的经验，是不行的），但是买的licheezero的板子已经画好了，看原理图也没有加上拉，就是引脚引出，这是表示自己要跳线吗。:|

buildroot可以局部清除，参考buildroot说明文档：https://buildroot.org/downloads/manual/manual.html#_advanced_usage,8.14.5
使用方法是 make <package>-<target>
下面是可用命令,make package-dirclean 表示移除目标package的build目录，还有很多选项，比如查看依赖：make qt5webkit-show-depends
gst1-plugins-base gstreamer1 host-bison host-cmake host-flex host-gperf host-pkgconf host-python3 host-ruby host-skeleton icu jpeg leveldb
libpng libxml2 libxslt openssl qt5declarative qt5location qt5sensors qt5webchannel skeleton sqlite toolchain webp woff2@forever_rainy
参考sipeed的文档，摸索了下，sipeed链接：https://wiki.sipeed.com/soft/Lichee/zh/Zero-Doc/System_Development/bsp_build.html
发现他的机制跟之前的都不一样，先使用buildroot下载工具链，再将工具链拷贝出去解压使用，这时就回到了之前的的思路。
另外buildroot确实对多线程是不支持的：https://buildroot.org/downloads/manual/manual.html#_buildroot_quick_start
（因为下载了buildroot2022编译了试试，多线程容易出错）
他这个多线程在新版本说起来也是实验，不是完全可用？
这里说明了要设置一个参数，可以在顶层使用parallel build，https://buildroot.org/downloads/manual/manual.html#top-level-parallel-build
但是是实验特性,选项为：
Build options--->
Advanced--->
Use per-package directories(experimental)
之后可以使用 make -jN
我也是新手，玩了快半月了，从 老版本，kernel 4.13 buildroot2017,到新版本kernel5.10，buildroot2022，有debian的根文件系统的制作，还有qt的交叉编译，坑人的ffmpeg，sdl的交叉编译，lvgl初次使用，坑点很多。
也是不知道linux3.4有什么玩法，就看到说这个对摄像头支持较好，倒是也没有试过，手里也没有摄像头，唯一有一个摄像头是ov5640，不过在老家。但是也看到有人用新的内核跑起摄像头（b站有个129先生）
如题
确实如 楼上所说，下载了最新的buildroot2022看了，mpv 是 mplayer2，使用新版本可以使用在这个，使用旧版本的话(buildroot2017)，因为我一直是下载的qt的源码手动交叉编译的，试过5.9.3 ， 5.12.7， 都可以使用。
我试过xfce桌面，不需要输入密码直接登录，不过手里只有240*280的st7789屏幕，显示不全，看起来很难受，操作起来卡顿很多，点开文件管理这种也是要卡顿的，不过也不是不能用。。。
你好
关于这段编译内核与uboot的工具链是不同，arm-linux-gnueabi工具是多少版本的，有要求吗，uboot是arm-linux-gnueabihf，我现在使用的主线uboot和内核（linux kernel官网下载的），也是使用的arm-linux-gnueabihf工具链，如果使用arm-linux-gnueabihf工具链编译3.4的内核，会报错的说。
uboot
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make LicheePi_Zero_480x272LCD_defconfig（因为配置文件里我默认的是4.3寸的屏幕）
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make LicheePi_Zero_800x480LCD_defconfig（这个也贴出来）
执行编译:
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4kernel
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage -j16
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j16 INSTALL_MOD_PATH=out modules
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j16 INSTALL_MOD_PATH=out modules_install咱觉得其实也可以交叉编译过去，，，不一定非要使用buildroot，虽然手动交叉编译是很麻烦就是了
没有有线网卡吗？很好奇有线网卡速度
啊，不是有一个emac的ethernet吗，我就一直用的这个网络啊，在linux kernel官网下载了5.10.1的内核，发现他emac的驱动用的是st的那套，不过能够正常使用，百兆网
某鱼两百来块 买了个拆机板（感觉不是很划算，前面这个板子他卖150，后面加到200，咱也没讲价，电源适配也没有），感觉rk没有v3s这些这么简单啊。。。
这里不是有吗：https://wiki.sipeed.com/soft/Lichee/zh/Zero-Doc/application/QT_doc1.html
关于qt的交叉编译，buildroot执着一个最小可用的文件系统就好，其他的可以自己交叉编译添加.我自己交叉编译了5.9.3,5.12.7，所有模块（web不行），还包含例子，运行没有一点问题的，但是说实话，这种性能不太行的，使用lvgl，速度刷新都更快，依赖更少。
lvgl使用链接：https://github.com/lvgl/lv_port_linux_frame_buffer.git
另外，buildroot我也很困扰，必须clean（不是好像，可能），重新编译才能生效，又不能使用多线程，改个东西，重新编，慢的很，也没有明显的找到有关说明。
再用的lvgl8.2,使用fb：https://github.com/lvgl/lv_port_linux_frame_buffer.git。
下载交叉编译即可，没有任何其他依赖...，但是st7789v在v3s上不是很流畅，可能说没有stm32硬件spi+dma流畅
https://stackoverflow.com/questions/62529964/u-boot-splashscreen-through-spi
这个也说明了，你看到的别人使用的在uboot启动时就行输出控制台的是uboot就支持的lcd的（uboot2017.01可以在在menuconfig配置，uboot configs下的从fig也有配置文件）
如果要适配st7789，确实要自己添加驱动到uboot，所以咱也没折腾，因为没有。。。
个人猜想，uboot启动时，想要屏幕显示东西，那么uboot一定是支持屏幕驱动的，需要看一下uboot配置，是否有屏幕的驱动相关设置。比如uboot支持网络，网上有相关说明。
我这里是kernel启动才会显示信息，使用的是st7789v驱动的屏幕，kernel也是配置了驱动的的。
hello
请教一个问题，在使用buildroot编译根文件系统，使用的时 buildroot2017.08.1这个文件的内容，编译的主机使用的ubuntu16.0.4 lts。编译是成功的，系统初始使用的是busybox，自己也添加了很多东西，但是出现了一个致命的问题。我的/etc/init.d/rcS在开机的时候没有执行。
首先，我确定以下文件的符后链接是正确的:/sbin/init（链接到了/bin/busybox），bash环境是ok的，文件有执行的权限，/etc/inittab有相应的执行命令，测试更改该文件内容，启动会变得不正常，说明该文件是正常执行了（该文件内的其他内容有被执行，比如设置的串口不需要密码自动登录）。开机后 /etc/init.d/文件夹下的内容没有执行（通过rcS执行该文件夹内容），我不知道是否是buildroot中某一个选项没有配置上。现在不知道怎么去解决这个问题。能提供一些帮助信息吗。
开机后手动执行/etc/init.d/rcS是成功的。
以下是/etc/inittab 的内容：
# Startup the system
::sysinit:/bin/mount -t proc proc /proc
::sysinit:/bin/mount -o remount,rw /
::sysinit:/bin/mkdir -p /dev/pts
::sysinit:/bin/mkdir -p /dev/shm
::sysinit:/bin/mount -a
::sysinit:/bin/hostname -F /etc/hostname
# now run any rc scripts
::sysinit:/etc/init.d/rcS
# Put a getty on the serial port
#console::respawn:/sbin/getty -L console 0 vt100 # GENERIC_SERIAL
ttyS0::respawn:/bin/sh
ttyS1::askfirst:/bin/sh
# Stuff to do for the 3-finger salute
#::ctrlaltdel:/sbin/reboot
# Stuff to do before rebooting
::shutdown:/etc/init.d/rcK
::shutdown:/sbin/swapoff -a
::shutdown:/bin/umount -a -r
找到原因了，串口登录时没有将一些信息，显示出来，问题在这句代码上：ttyS0::respawn:/bin/sh，这个暂时还没有搞明白怎么解释这个
手机屏幕一样的，要是能够自己驱动，不也是一件很好的事，就是空有个硬件，没有啥资料啊
