      1. 下载 dropbear-D1.tgz源码 (尴尬, 没找到上传菜单), 解压, 编译:

      根据实际情况修改 gcc 路径

      CROSS=/opt/D1/prebuilt/gcc/linux-x86/riscv/toolchain-thead-glibc/riscv64-glibc-gcc-thead_20200702/bin/riscv64-unknown-linux-gnu- make
      
      1. 修改 wifi 热点配置
      package/allwinner/wifimanager/files/wpa_supplicant_overlay.conf
      
      disable_scan_offload=1
      
      network={
          ssid="whycan"
          psk="13800138000"
      }
      
      1. 修改文件系统, 添加文件 allwinner/d1-nezha/base-files/etc/init.d/S51dropbear
      # Allow a few customizations from a config file
      test -r /etc/default/dropbear && . /etc/default/dropbear
      
      start() {
              DROPBEAR_ARGS="$DROPBEAR_ARGS -R"
      
              # If /etc/dropbear is a symlink to /var/run/dropbear, and
              #   - the filesystem is RO (i.e. we can not rm the symlink),
              #     create the directory pointed to by the symlink.
              #   - the filesystem is RW (i.e. we can rm the symlink),
              #     replace the symlink with an actual directory
              if [ -L /etc/dropbear \
                   -a "$(readlink /etc/dropbear)" = "/var/run/dropbear" ]
              then
                      if rm -f /etc/dropbear >/dev/null 2>&1; then
                              mkdir -p /etc/dropbear
                      else
                              echo "No persistent location to store SSH host keys. New keys will be"
                              echo "generated at each boot. Are you sure this is what you want to do?"
                              mkdir -p "$(readlink /etc/dropbear)"
                      fi
              fi
      
              printf "Starting dropbear sshd: "
              umask 077
      
              start-stop-daemon -S -q -p /var/run/dropbear.pid \
                      --exec /usr/sbin/dropbear -- $DROPBEAR_ARGS
              [ $? = 0 ] && echo "OK" || echo "FAIL"
      }
      stop() {
              printf "Stopping dropbear sshd: "
              start-stop-daemon -K -q -p /var/run/dropbear.pid
              [ $? = 0 ] && echo "OK" || echo "FAIL"
      }
      restart() {
              stop
              start
      }
      
      case "$1" in
        start)
              start
              ;;
        stop)
              stop
              ;;
        restart|reload)
              restart
              ;;
        *)
              echo "Usage: $0 {start|stop|restart}"
              exit 1
      esac
      
      exit $?
      

      把前面编译的 dropbear 复制到 allwinner/d1-nezha/base-files/usr/sbin/

      1. 执行编译/打包/烧录:
      source build/envsetup.sh;lunch d1_nezha-tina;make;pack
      
      1. 启动手动执行 (因为还不会自动执行, 折腾了很多次也没搞定)
      #获取IP
      udhcpc -i wlan0
      
      #启动ssh服务
      /etc/init.d/S51dropbear restart
      
      root@TinaLinux:/# udhcpc -i wlan0
      udhcpc: started, v1.27.2
      udhcpc: sending discover
      udhcpc: sending select for 192.168.43.224
      udhcpc: lease of 192.168.43.224 obtained, lease time 3599
      udhcpc: ifconfig wlan0 192.168.43.224 netmask 255.255.255.0 broadcast 192.168.43.255
      udhcpc: setting default routers: 192.168.43.1
      root@TinaLinux:/#
      root@TinaLinux:/#
      root@TinaLinux:/# /etc/init.d/S51dropbear restart
      Stopping dropbear sshd: OK
      Starting dropbear sshd: OK
      
      1. 给板子的root设置一个密码 passwd

      2. 用 Xshell, mobaxterm, putty, ssh命令行等都可以连接到 192.168.43.224

          root@TinaLinux:/# /etc/init.d/S51dropbear restart
          Stopping dropbear sshd: FAIL
          Starting dropbear sshd: start-stop-daemon: unrecognized option '--exec'
          

          需要将--exec改为-x
