1.下载 git clone https://gitee.com/orangepi-xunlong/opi-bkimg.git
2.进入当前目录下的 opi-bkimg
3.sudo ./opi-bkimg
4.生成img文件在/mnt文件夹

0.修改密码
sudo passwd root
sudo passwd orangepi

nmcli connection delete uuid XXXX

1.连接无线
sudo nmcli –ask dev wifi connect mini_5G password fsw2021fsw ifname wlan0

sudo nmcli –ask dev wifi connect TP-LINK_7787 password yyxlx18396870603 ifname wlan0

sudo nmcli –ask dev wifi connect mini_5G password fsw2021fsw ifname wlx7822884b2787

sudo nmcli –ask dev wifi connect rtlwap password mqdqxyg1qy ifname wlx7822884b2787
sudo nmcli dev wifi connect password ifname

2.安装ssh
sudo apt-get install openssh-server
3.安装vnc
sudo set_vnc.sh
连接VNC 端口号为5901
4.安装qt
sudo install_qt.sh

5.

1.加载ko模块
sudo insmod wlanrtl.ko rtw_country_code=”CN” 或者 insmod wlanrtl.ko 并且 echo 0x3E > /proc/net/rtl88x2eu/wlx7822884b2786/chan_plan

2.确保hostapd文件夹是否存在，如不存在新建文件
sudo mkdir -p /var/run/hostapd

3.进入cd /usr/sbin

4.在/usr/sbin文件夹下新建1.config文件
————-1.config————–
interface=wlx7822884b2786
ctrl_interface=/var/run/hostapd
ssid=rtlwap
channel=36
wpa=2

wme_enabled=1
ht_capab=[SHORT-GI-20][SHORT-GI-40][HT40+]
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP

4.执行sudo ./hostapd 1.config -B

5.如无IP地址，sudo ifconfig wlx7822884b2786 192.168.16.1

内核中执行
sudo make mrproper # 清理源码树
sudo make menuconfig ARCH=arm64 CROSS_COMPILE=/opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-
sudo make prepare ARCH=arm64 CROSS_COMPILE=/opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu- # 准备编译环境，包括生成头文件
sudo make scripts ARCH=arm64 CROSS_COMPILE=/opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu- # 生成 scripts，包括 genheaders 等工具
sudo make modules_prepare ARCH=arm64 CROSS_COMPILE=/opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu- modules_prepare

驱动中执行
make ARCH=arm64 CROSS_COMPILE=/opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-

endif

1.修改bootargs
①修改u-boot
②修改dts文件的
chosen: chosen {
bootargs = “earlycon=uart8250,mmio32,0xfe660000 console=ttyFIQ0 isolcpus=3”;
};

2.隔离cpu，不让程序运行在CPU3上 isolcpus=3

3.查看bootargs cat /proc/cmdline

1.下载源码
http://qt-mirror.dannhauer.de/archive/qt/5.15/5.15.2/single/
2.解压
tar -xvf xxxx
3.在源码根目录下放如autoconfig.sh ,注意sysroot ，可能需要添加-feature-library 选项

./configure \
-prefix /opt/qt-5.15.2 \
-release \
-feature-library \
-opensource \
-skip qtwayland \
-skip qtlocation \
-skip qtscript \
-xplatform linux-aarch64-gnu-g++ \
-sysroot /opt/atk-dlrk356x-toolchain/aarch64-buildroot-linux-gnu/sysroot/ \
-make libs \
-optimized-qmake \
-no-opengl \
-no-sse2 \

-no-glib \
-no-pkg-config \
-no-separate-debug-info \
-pch \
-shared \
-qt-libjpeg \
-qt-zlib \
-qt-libpng

另外一种测试
./configure \
-prefix /opt/qt-5.15.2 \
-opensource -confirm-license \
-release \
-strip \

4.修改 qtbase/mkspecs/linux-aarch64-gnu-g++/qmake.conf

QMAKE_CC = /opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-gcc
QMAKE_CXX = /opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-g++
QMAKE_LINK = /opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-g++
QMAKE_LINK_SHLIB = /opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-g++

# modifications to linux.conf
QMAKE_AR = /opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-ar cqs
QMAKE_OBJCOPY = /opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-objcopy
QMAKE_NM = /opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-nm -P
QMAKE_STRIP = /opt/atk-dlrk356x-toolchain/bin/aarch64-buildroot-linux-gnu-strip

4.1 修改
src/corelib/global/qglobal.h 里添加limits头文件
# include 一定要加在ifdef __cplusplus和endif之间才行

5.sudo make -j4
6.sudo make install
7.完成后应该在/opt/atk-dlrk356x-toolchain/aarch64-buildroot-linux-gnu/sysroot/opt下有qt5.15.2目录
8.将qt5.15.2打包传到开发板
9.将解压后的qt-5.15.2/lib目录添加到开发板的LD_LIBRARY_PATH环境量中
