rk3568系统buildroot开发笔记

编译异常

in from _bz2 import BZ2Compressor, BZ2Decompressor ModuleNotFoundError: No module named ‘_bz2’

sudo apt-get install libbz2-dev
然后删掉
rk356x_bsp_bak/rk356x_bsp/build-iot/buildroot_output/rockchip_rk3568_iot/build/host-python3-3.10.5
重新编译

ERROR: Feature ‘webengine-system-libxml2’ was enabled, but the pre-condition ‘config.unix && libs.webengine-libxml2’ failed.

查看日志,原因的编译xml2的时候没开icu

> main.cpp:4:2: error: #error libxml icu not enabled
>     4 | #error libxml icu not enabled
>       |  ^~~~~

把这个libxml2-2.9.14 项目删了重新编译过就行了

error: there are no arguments to ‘uloc_openAvailableByType’ that depend on a template parameter, so a declaration of ‘uloc_openAvailableByType’ must be available [-fpermissive]

undefined reference to `icu_70::UnicodeSet::getRangeStart(int) const’

uloc_openAvailableByType(ULOC_AVAILABLE_WITH_LEGACY_ALIASES, &status);

编译的时候缺少头文件

去这里把 intl-objects.h 头文件加上

#include “unicode/uloc.h”

加上以后发现还是不行, 看了下文件路径这次编译是来源于系统的头文件,Ubuntu18.04 icu版本低,

下载
icu70 https://github.com/unicode-org/icu/releases/tag/release-70-1
icu-release-70-1/icu4c/source$ ./configure
./configure
make -12
sudo make install
//卸载掉原来系统的icu,不然依赖会错误
apt autoremove libicu-dev

unicode/uchar.h: No such file or directory

和上面一样

注释掉openbox

# BR2_PACKAGE_OPENBOX=y

make: *** No rule to make target ‘xwayland’,

大致原因就是缺少xwayland 的库 ,这个是一个独立的packet,他在新的buildroot里面可以找到

然后把它拷贝到sdk 的buildroot里面再编译

meson.build:41:2: ERROR: Problem encountered: Failed to find matched library

找不到 x11-wayland-gbm 这个名字的库,
原厂没有默认编译出来这个库 , 拿wayland-gdm换名字先跳过
因为想要编译Xwayland  ,那么 xorg又一定要开

qt5x11extras安装失败

注释了libgtk3的服务编译

然后整个系统重新编译

qt5base编译异常

多线程编译导致的冲突, 再运行异常就行

运行异常

eth0 被重命名成了 FE0

ubuntu22.04的用户密码哈希在新系统用不了

通过搜索mkpasswd了解到,他们的生成逻辑

2024-03-16T18:07:09 /usr/bin/sed -i -e s,^root:[^:]*:,root:"`/home/genvict/rk356x_bsp/build-iot/buildroot_output/rockchip_rk3568_iot/host/bin/mkpasswd -m "sha-256" "rockchip"`":, /home/genvict/rk356x_bsp/build-iot/buildroot_output/rockchip_rk3568_iot/target/etc/shadow

这个命令是使用 sed 工具在文件 /etc/shadow 中替换 root 用户的密码哈希值。

它使用了 mkpasswd 命令生成新的哈希值，然后将其插入到 /etc/shadow 文件中。

这样可以更新 root 用户的密码。

根据命令中的参数 -e s,^root:[:]*:,root:“/home/genvict/rk356x_bsp/build-iot/buildroot_output/rockchip_rk3568_iot/host/bin/mkpasswd -m “sha-256” “rockchip””:，可以看出密码是由 mkpasswd 命令生成的，使用 SHA-256 算法，密码参数为 “rockchip”。

调试过程

root@genvict:/home/genvict/rk356x_bsp# /home/genvict/rk356x_bsp/build-iot/buildroot_output/rockchip_rk3568_iot/host/bin/mkpasswd -m "sha-256" "rockchip"

开机加载eth业务

buildroot 编译出来的systemd默认用 /etc/systemd/network/01-ETH0-static.network 这种方式加载网卡信息

[Match]
Name=eth0  # 根据你的实际网卡名称修改[Network]
Address=192.168.1.100/24  # 设置静态 IP 地址和子网掩码
Gateway=192.168.1.1  # 设置网关地址
DNS=8.8.8.8  # 设置 DNS 服务器地址

如果要支持旧版那种方式 /etc/network/interfaces.d/eth0

需要启用这些服务 , 以及他的一类关联

切换Xorg异常 Failed to load /usr/lib/xorg/modules/drivers/modesetting_drv.so: /usr/lib/xorg/modules/drivers/modesetting_drv.so: undefined symbol: glamor_egl_create_textured_pixmap

看依赖是没开GLAMOR_HAS_GBM, 但其实有开,原因不明

最后从原厂debian的deb包里面各种偷龙转凤,根本原因应该是依赖问题

具体是哪个没仔细找

PulseAudio 运行异常

systemctl stop pulseaudio

然后，创建所需的 cookie 文件。你可以使用 touch 命令来创建空的文件，如果文件已经存在，touch 命令不会做任何事情：

touch /var/run/pulse/.config/pulse/cookie
touch /var/run/pulse/.pulse-cookie

确保 PulseAudio 有足够的权限来访问这些文件。你可以使用 chown 命令来改变文件的所有者，假设你的 PulseAudio 服务以 ‘pulse’ 用户运行：

chown pulse:pulse /var/run/pulse/.config/pulse/cookie
chown pulse:pulse /var/run/pulse/.pulse-cookie

最后，重新启动 PulseAudio 服务：

systemctl start pulseaudio

amixer 运行异常

ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Access deniedamixer: Mixer attach default error: Connection refused

确保 PulseAudio 服务正在运行

在命令行中输入 pulseaudio --check，如果没有返回任何东西，那就表示 PulseAudio 服务正在运行。
如果返回错误信息，那就代表 PulseAudio 服务没有运行，你可以尝试使用 pulseaudio --start 命令启动它。

检查用户是否有权限访问 PulseAudio

在命令行中输入 groups 查看当前用户所在的用户组。如果列表中没有 pulse-access 或 audio，那就表示当前用户没有访问 PulseAudio 的权限。
你可以使用 usermod -aG pulse-access your_username 或 usermod -aG audio your_username 命令把用户添加到这些组。

如果以上方法都不行，你可以尝试使用 ALSA 而不是 PulseAudio。

解决方法

hdmi 原生接口空载上电无显示, 默认激活

enum drm_connector_status dw_hdmi_phy_read_hpd(struct dw_hdmi *hdmi,void *data)
{//修改为默认连接状态return connector_status_connected;return hdmi_readb(hdmi, HDMI_PHY_STAT0) & HDMI_PHY_HPD ?connector_status_connected : connector_status_disconnected;
}

系统默认功放被USB摄像头插入后替换

固定rockchiprk809co为默认声卡

#!/bin/bash# 使用 awk 从 /proc/asound/rockchiprk809co/pcm0p/info 文件中获取 id
id=$(cat /proc/asound/rockchiprk809co/pcm0p/info | awk 'NR==1 {print $2}')# 将 id 写入 /etc/asound.conf 文件
echo "defaults.ctl.card $id" > /etc/asound.conf
echo "defaults.pcm.card $id" >> /etc/asound.conf
echo "defaults.timer.card $id" >> /etc/asound.confamixer cset name='Playback Path' SPK_HP
