这是什么原因呢

有没有 /dev/i2cX, /dev/i2c/X 这些设备，如果没有可能是 menuconfig 上面没有勾选 I2C User Interface

晕哥说：

晕哥 · 2019-05-15 13:44:08

看前面的错误，觉得应该是没有生成 /dev/videoX 设备，

看log 果然是视频设备没有注册成功:

[ 1.418282] [VFE]v4l2 subdev register input_num = 0

[ 1.445540] [VFE_ERR]Error registering v4l2 subdevice No such device!

menuconfig 里面有 ov5640 吗？ ov5640 与 ov5647 的设备Id 不同的。

晕哥小弟 · 2019-05-15 13:46:25

不对吧，你往下看，产生了 /dev/video1啊

嗯，眼花了。

找到这个，问题和你的一样，
https://licheezero.readthedocs.io/zh/latest/系统开发/bsp_cam.html

但是我仍然没看出来他是如何解决的.

晕哥小弟 · 2019-05-15 14:29:25

这就咋玩了，主线生成不了/dev/video* BSP 虽然生成了/dev/video1但是拍照会发生上面的错误。。。。。。

我这边是得到的消息是 ov5647停产了。而且市面上不好购买。另外我用fswebcam拍照的话，10次大概有1-2次拍照出来是个空照片。

我这边是得到的消息是 ov5647停产了。而且市面上不好购买。另外我用fswebcam拍照的话，10次大概有1-2次拍照出来是个空照片。
用上面的固件，会有空照片?

是的，我之前测试的时候发现的，好像拍了十几张的样子，然后有一张图片生成了，但是就是没有图像。后来我就没有管了。换linux了。

晕哥说：
先用 bmp 文件测试, 如果 bmp 文件都正常, 说明缺 png 库.
那可能 buildroot 没有勾上 libpng,
也可能勾上了 libpng,
但是你的 Qt 路径, plugins 子目录下面没有 png 插件,
缺一不可.
折腾了两天，终于能显示png了。。。
确实在buildroot里面勾上 png相关支持就可以了，然后要删除掉qt5目录内的.stamp_built .stamp_configured 。
刚开始我没删掉这些，生成的根文件系统还是不支持显示png
感觉自己蠢哭了。。。

我也遇到了这个问题，请问是删除掉“./buildroot-2017.08.1/output/build/qt5base-5.9.1/.stamp_built”，和 “./buildroot-2017.08.1/output/build/qt5base-5.9.1/.stamp_configured” 这两个目录下的文件么，请指教！！

可以先这样试一试

晕哥，有方法可以把主线的uboot.bin + bsp kernel + script.bin 等等打包一个img文件，我烧到flash中，之前好像在论坛里面看到。今天早了很长时间没有找到。

晕哥，上面你提供的链接，我搜到了，我现在的环境是主线u-boot + BSP 内核。想烧写到spi-flash中。

可以的，貌似我以前做过 flash 固件, 刚刚没找到。

晕哥小弟 · 2019-05-16 08:51:54

我其实不需要固件，我需要个步骤。因为现在我有主线的uboot BSPkernel + boot.scr + script.bin +还有一个rootfs (我不知道是什么格式，是buildroot生成的) 这些我不知道烧写到什么位置。

晕哥小弟 · 2019-05-16 10:27:41

晕哥，按照自己的理解，和参照网上。自己折腾了下。

串口连 u-boot 信息都没有？

到这里跟帖吧:

Console: switching to colour dummy device 80x30

感觉应该是你的 u-boot bootargs 里面的 console 参数不是 /dev/ttyS0

导致默认控制台发生了切换.

jianke512 · 2019-05-17 17:17:37

晕哥，在Kernel的log中已确认console=ttyS0,与你在一楼推荐的CONFIG_BOOTARGS设置一样

晕哥版主:“buildroot-2017.08.1” 自带的/usr/bin/ts_calibrate,测试时，提示“tslib: Selected device is not a touchscreen (must support ABS and KEY event types)”。以前手动按装tslib. 设置：export TSLIB_TSDEVICE=/dev/input/event1
就可以找到touchscreen ， “buildroot-2017.08.1” 自带的/usr/bin/ts_calibrate设置没有效果。

提示“tslib: Selected device is not a touchscreen (must support ABS and KEY event types)”。

是 TSLIB_TSDEVICE 环境变量没有测试

那现在可以了吗?

lgliang · 2019-05-19 16:49:34

手动export TSLIB_TSDEVICE=/dev/input/event1 就可以了，我之前把这个命令写入/etc/profile里面没有效果，发现这个电阻触摸屏不是很准确。有时会跳动

触摸不准是因为驱动没有防抖, 据说 tslib 的插件有防抖功能, 你研究一下.

驱动防抖 @john78 大神已经实现了: https://whycan.cn/t_1259.html#p14265

软解。

因为硬解码没有统一的标准。

我跟着教程都走通了，但是挂载emdebian系统后，启动时出错了，emdebian系统是根据https://licheezero.readthedocs.io/zh/latest/系统开发/emdebian.html制作的，错误是Starting init: /etc/init exists but couldn't execute it (error -13)
/bin/sh: 0: Can't open earlyprintk，没找到原因，有了解的能指点下吗。

nuvoton · 2019-06-19 15:46:49

/etc/init exists but couldn't execute it (error -13)

/etc/init 存在，但是不能执行, 看文件是不是没有执行属性，或者依赖的库不存在，还是别的问题？

tobunto · 2019-06-20 09:13:32

debian系统的/etc/init是个目录，/etc/init/下也都是一些配置文件，应该与执行权限没关

那你的 bootargs 是什么? 系统第一个执行程序是 init=/etc/init ?

tobunto · 2019-06-20 09:35:47

没指定第一个启动程序，是按帖子上面的配的：#define CONFIG_BOOTARGS "console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw rootfstype=ext4 rootdelay=8 vt.global_cursor_default=0"

我用win10的subsystem编译出现了这个错误，似乎是wsl内部IPC实现的问题
一会儿换用doker编译看看，可以的话我上传个编译用的docker镜像

你这个咋跟官方介绍的不一样呢？是因为官方的是最新的编译方式吗？我的板子是最新买的，按你的编译过程，烧进去，跑步起来，串口也没信息。如果，烧lichee_zero_test_Debian_LXDE，就可以跑起来，说明硬件没问题。可能是编译哪里不对。晕哥，能帮我分析下吗？

按照论坛里的教程：
1) 删除TF卡所有分区
2) 将uboot写入到sd卡8k偏移处(必须8K偏移, brom龟腚的)。
sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8
3) 建立第一个分区,大小32M(可以随意填写), 格式FAT16, 把zImage, sun8i-v3s-licheepi-zero-dock.dtb拷贝到这个分区
4) 建立第二个分区，用尽剩余空间,格式ext4, 把buildroot产生的rootfs.tar解压到该分区根目录
tar xvf output/images/rootfs.tar -C /挂载的tf卡第二个分区目录

在V3S ZERO开发板上运行后，出现如下情况：

板子启动不了？是什么情况？

如果把第二步改一下：
4) 建立第二个分区，大小100M,格式ext4, 把buildroot产生的rootfs.tar解压到该分区根目录
tar xvf output/images/rootfs.tar -C /挂载的tf卡第二个分区目录
第二个分区改成100M，就可以正常启动。200M就不行了，是什么问题呢？

遇到同样问题，该如何解决？

换了张SD可以了，但是按照
1) 删除TF卡所有分区
2) 将uboot写入到sd卡8k偏移处(必须8K偏移, brom龟腚的)。
sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8
3) 建立第一个分区,大小32M(可以随意填写), 格式FAT16, 把zImage, sun8i-v3s-licheepi-zero-dock.dtb拷贝到这个分区
4) 建立第二个分区，用尽剩余空间,格式ext4, 把buildroot产生的rootfs.tar解压到该分区根目录
sudo tar xvf output/images/rootfs.tar -C /media/bao/rootfs
这样子烧写到SD卡
偶尔几次就又启动不了，偶尔几次又可以

写一个简单的 HelloWorld app程序, 用gcc编译,

比如路径是 /opt/helloworld

你创建 /etc/profile.d/app 文件

添加一行: /opt/helloworld

就能开机执行了.

建议在vultr的日本vps上面编译, 没有进度条问题，可以按时长租用，销毁实例停止收费:

好不容易把串口调试通了，但是发现串口波特率设置高了(比如115200)就不能通信了，怎么让高频率的也能用，请教大神指点

又一个入坑的重头开始炒作业

yelong98 · 2021-04-02 03:41:48

这个上手教程贴有更新么？看起来还是3年前的了

mysteryli · 2021-04-02 10:52:47

最高只能用到115200

感谢分享，亲测成功运行，可以扫描到wifi的SSID了，验证了硬件没问题，回头会测试一下是否可以连接并上网！

千石级灯说：

@晕哥
晕哥这次我终于调试好v3s的esp8089的驱动了呢
（1）下载源码 https://github.com/al177/esp8089
修改Makefile，修改如下的内容：
KVERS_UNAME = 4.13.16-licheepi-zero+
KVERS_ARCH = arm
KBUILD ?=/home/gec/v3s/linux4.13-y/linux
modules:
$(MAKE) ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -C $(KBUILD) M=$(SRC_DIR)
然后直接在文件夹内make 即可生成esp8089.ko文件
（2）参考RTL8723bs的配置方法
a.wpa_supplicant-2.6交叉编译
使用wpa_supplicant与wpa_cli相关的工具测试wifi
（1）1. libnl交叉编译
下载：https://www.infradead.org/~tgr/libnl/files/libnl-1.1.4.tar.gz
解压：tar zxvf libnl-1.1.4.tar.gz
cd libnl-1.1.4/
配置
./configure --prefix=/mnt/nfsroot/frank.yu/android-O/factorytest/wifi/out
删除：（这一步一定不能忘记）
rm lib/libnl.a
可能导致编译报错（编译出错Relocations in generic ELF (EM: 62)）
编译：make CC=arm-linux-gnueabihf-gcc AR=aarch64-linux-gnu-ar LD=arm-linux-gnueabihf-ld
make install
（2）openssl-1.0.0交叉编译
下载：https://www.openssl.org/source/old/1.0.1/openssl-1.0.1s.tar.gz
解压：tar -xzvf openssl-1.0.0.tart.gz
配置：
./config no-asm shared --prefix=/mnt/nfsroot/frank.yu/android-O/factorytest/wifi/out
修改makfile：
（1）修改交叉编译器
CC= gcc
AR= ar $(ARFLAGS) r
RANLIB= /usr/bin/ranlib
NM= nm
修改为：
CC=arm-linux-gnueabihf-gcc
AR= arm-linux-gnueabihf-ar $(ARFLAGS) r
RANLIB= arm-linux-gnueabihf-gcc-ranlib
NM= arm-linux-gnueabihf-gcc-nm
（2）去掉里面的-m64

make make install
备注：
no-asm是在交叉编译过程中不使用汇编代码代码加速编译过程.原因是它的汇编代码是对arm格式不支持的。我试过了，如果没有这个参数，你的交叉编译一定出错。shared生成动态连接库。prefix=路径就是你的安装目录。
3. wpa_supplicant交叉编译
下载：http://hostap.epitest.fi/releases/wpa_supplicant-2.6.tar.gz
解压：tar -zxvf wpa_supplicant-2.6.tar.gz
cd wpa_supplicant-2.6/wpa_supplicant
拷贝配置：
cp defconfig .config
修改.config
（-O后面不能有空格）
CC=arm-linux-gnueabihf-gcc -L/mnt/nfsroot/frank.yu/android-O/factorytest/wifi/out/lib
CFLAGS += -I/mnt/nfsroot/frank.yu/android-O/factorytest/wifi/out/include
LIBS += -L/mnt/nfsroot/frank.yu/android-O/factorytest/wifi/out/lib
makefile修改：（这里是为了生成静态链接的bin文件）
wpa_supplicant: $(BCHECK) $(OBJS) $(EXTRA_progs)
$(Q)$(LDO) $(LDFLAGS) -o wpa_supplicant $(OBJS) $(LIBS) $(EXTRALIBS)
@$(E) " LD " $@
修改为
wpa_supplicant: $(BCHECK) $(OBJS) $(EXTRA_progs)
$(Q)$(LDO) --static $(LDFLAGS) -o wpa_supplicant $(OBJS) $(LIBS) $(EXTRALIBS) -lm -lpthread
@$(E) " LD " $@
wpa_cli: $(OBJS_c)
$(Q)$(LDO) $(LDFLAGS) -o wpa_cli $(OBJS_c) $(LIBS_c)
@$(E) " LD " $@
修改为
wpa_cli: $(OBJS_c)
$(Q)$(LDO) --static $(LDFLAGS) -o wpa_cli $(OBJS_c) $(LIBS_c)
@$(E) " LD " $@
编译：
make
即可生成静态链接的wpa_supplicant/wpa_cli工具，不需要依赖其他的库文件。
工具wpa_cli ,wpa_passphrase,wpa_supplicant拷贝进开发板的/bin 目录

三，在开发板中设置
（1）insmod esp8089.ko
然后输入ifconfig wlan0 up命令启动wlan0
(3)建立 /etc/wpa_supplicant.conf 文件:
#可有可无，没有的话无法用wpa_cli terminate来关闭wpa_supplicant
ctrl_interface=/var/run/wpa_supplicant
# 确保只有root用户能读取WPA的配置，可有可无，尤其是在嵌入式设备上
ctrl_interface_group=0
# 使用wpa_supplicant来扫描和选择AP，也可以设置成0或2，但只有1才能正确工作
ap_scan=1
#设置需要链接上的网络信息
network={
ssid="unicompy1F"
scan_ssid=1
key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
pairwise=TKIP CCMP
group=CCMP TKIP WEP104 WEP40
psk="unicomp#38468350"
priority=5
}
(4)输入命令wpa_supplicant -B -d -i wlan0 -c /etc/wpa_supplicant.conf
使用这个命令来链接上wifi
测试wlan0: udhcpc -i wlan0
补充：运维常用linux命令整理
1.临时添加
1 route add default gw 192.168.1.4
2.永久添加
12 vim /etc/sysconfig/networkGATEWAY=192.168.1.4
(5)配置网络ping通外网部分了
一.手动测试是否成功加载网卡驱动，可执行如下命令：ifconfig eth0 192.168.1.218 up
二。以下是在配置好内核以及成功加载网卡的前提下实现能够自动配置网络，能够ping通的步骤
（1）修改 /etc/network/interfaces
即vi /etc/network/interfaces后添加如下语句：
auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet static
address 192.168.1.218 # 3 你要变化的IP地址
gateway 192.168.1.251 （该网关最好需要设置成跟电脑的网关一致，我这里是 192.168.1.251,跟路由器设置相关）
netmask 255.255.255.0
（2）vi /etc/resolv.conf
添加以下语句
nameserver 127.0.0.1
nameserver 202.96.134.33
nameserver 114.114.114.114
（3）为了能够实现自动开机设置
nameserver 127.0.0.1
nameserver 202.96.134.33
nameserver 114.114.114.114
可以 vi /etc/init.d/rcS
然后添加以下三句即可：
echo "nameserver 127.0.0.1" > /etc/resolv.conf
echo "nameserver 202.96.134.33" >> /etc/resolv.conf
echo "nameserver 114.114.114" >> /etc/resolv.conf
之后就可以直接ping通了！！！

折腾到后半夜终于正常登录了，但是uboot可以看到lcd有输出，之后一直保持蓝色屏幕，串口后台能登录，请问大佬怎么可以lcdu也能显示出来登录界面？

mysteryli · 2021-04-04 22:05:34

来还愿了，测试速度看下图，内网ssh传输，天线设计的不好，所以只是勉强能用

切换到主线试试，哈哈

sunxiang · 2021-10-02 01:07:28

现在有个问题，我看大家的背光脚都是pb4，pb5。因为我这个板子是参照樱桃派画的，背光脚在pb2。跑bsp版本的时候，lcd可以正常亮起来。我不知道，如果切换主线的话，pb2是可以模拟pwm，以实现背光吗？可以给一个思路吗？

不行，定时器IO模拟的PWM第一浪费CPU，第二不准。

谢谢晕哥。我自己编译到uboot就不动了

我搞了两天，硬是没搞出来。。。

jack123321 · 2021-12-13 13:14:37

楼主一开始那个修改文件是增加还是全删除了用您的？

jack123321 · 2021-12-13 13:20:53

3). 执行编译, 生成文件跟文件系统。执行编译是在bulildroot目录下执行编译:
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make
这个吗？

晕哥有没有移植过H616的uboot，我用的是香橙派zero2开发板，自己移植uboot一直没成功，头大，可以指点一下吗

hahahah · 2022-06-15 00:27:50

我也遇到了5秒重启的问题，全部都是按照教程来的，前几次烧录成功正常启动可以进系统，后来又试了几次一直都有问题，不能理解，我前面整套流程下来至少2次都成功了，后面就出现这个问题，方法一模一样就是不对，我也是醉了

我怎么bulidroot出错？而且tf卡第一个分区挂载不了

我按教程试了一遍，使用tf卡启动，结果lcd没反应，连uart0串口都没识别出来T T

砍柴少年 · 2023-08-30 21:21:18

小白发问，想知道为啥官方镜像，8G的TF卡，烧录后可用的内存只有几百兆啊:(

paul_zdchun · 2024-03-13 12:06:37

内存几百兆?内存这个概念看来要好好定义一下
