昇腾开发板使用简要说明

1、SSH登录开发板

1.1 将烧录好的 SD 卡，插入开发板

断电状态下（即开发板没有通电源），插入已经烧录好的 SD 卡。如何烧录，可参考官网相关链接，此处从略。

1.2 给开发板插上电源

插上电源后，开发板上的三个绿灯，会逐个点亮。稍等一会后，三个绿灯都亮了，则表示启动成功。

1.3 用网线连接电脑和开发板

1.3.1 （可选）电脑如果没有空闲网口，可在电脑 USB 上插 USB转网口的转接器，以获得一个空闲网口。
1.3.2 网线一端，插入电脑的空闲网口。
1.3.3 网线另一端，插入开发板的网口。开发板有 2 个网口，上下排列，要插入上面那个网口。

1.4 设置电脑的 IP 地址，以便通过网线访问开发板

把电脑的 IP 地址，设置为和开发板同一个网段的地址。
打开：设置 | 网络。找到 USB 网口对应的网络适配器，修改 IP 地址的相关设置。

设置 [DHCP]：手动
设置 [IPV4]：ON
设置 [IP]：192.168.137.xxx。可用的网址可以是：
- 192.168.137.0：不可用，因为 0 是网络号。
- 192.168.137.1 ~ 192.168.137.99：可用。比如，可以将电脑的 IP 地址设置为 192.168.137.1，或者192.168.137.2，或者192.168.137.3，……，或者192.168.137.99。
- 192.168.137.100：不可用，因为被开发板占用了。开发板上下排列的2个网口，上面那个网口的 IP 地址固定为 192.168.137.100。
- 192.168.137.101 ~ 192.168.137.254：可用。比如，可以将电脑的 IP 地址设置为 192.168.137.101，或者192.168.137.102，或者192.168.137.103，……，或者192.168.137.254。
- 192.168.137.255：不可用，因为 255 是广播地址。
设置 [子网掩码]。设置长度或掩码，视操作系统版本不同而不同。
- 设置 [子网掩码长度]： 24
- 或者 [子网掩码]： 255.255.255.0
设置 [网关]。
视操作系统版本不同而不同。有的要求设置，否则无法保存。
如要求设置，可填写 192.168.137.xxx。xxx在上述可选的取值范围内，并且和本机设置的 IP 地址不同即可，因为网关实际上不用到。比如 192.168.137.1。
点击 [保存]

1.5 测试电脑和开发板之间网络是否连通

在电脑上启动命令行终端程序（比如 Windows 操作系统的 cmd，或者 powershell），并在命令行终端上执行
ping 192.168.137.100
如能看到如下信息，则表明电脑和开发板之间的网络是连通的。

~ % ping 192.168.137.100
PING 192.168.137.100 (192.168.137.100): 56 data bytes

round-trip min/avg/max/stddev = 0.450/0.634/0.775/0.121 ms

说明：192.168.137.100 是开发板 IP 地址，当网线插入开发板上下排列的2个网口的上面那个网口时。

1.6 通过 ssh 登录开发板

在电脑的命令行终端中执行如下命令登录开发板：
ssh HwHiAiUser@192.168.137.100

命令说明：
ssh
--通过 ssh 登录

HwHiAiUser
--以开发板上的 HwHiAiUser 账号登录

192.168.137.100
--开发板 IP 地址，当网线插入开发板上下排列的2个网口的上面那个网口时

屏幕提示
HwHiAiUser@192.168.137.100's password:
时，输入密码
Mind@123
输入密码完成后按回车键。
密码输入过程中，屏幕不会有回显，这是正常的，不必担心。

当输入正确密码后，就可以登录开发板，并看到如下信息。

~ % ssh HwHiAiUser@192.168.137.100
HwHiAiUser@192.168.137.100's password: 
    _                                _             _               _     _  _

也可以通过开发板的 root 账号登录开发板。命令是
ssh root@192.168.137.100
密码也是
Mind@123

2、运行开发板的预置样例

2.1 启动开发板的预置样例

参考 1、SSH登录开发板，用开发板的 HwHiAiUser 账号，或者 root 账号，ssh 方式登录开发板。

然后执行 cd 命令，切换到开发板的 /home/HwHiAiUser/samples/notebooks 目录。

用 HwHiAiUser 账号（或者 root 账号）执行命令：cd /home/HwHiAiUser/samples/notebooks
用 HwHiAiUser 账号（或者 root 账号）执行命令：pwd
确认的确已切换到目标目录了。如果屏幕回显如下，则表示已切换到目标目录。
/home/HwHiAiUser/samples/notebooks

在目录 /home/HwHiAiUser/samples/notebooks 中，执行命令：
./start_notebook.sh

可看到如下信息，表示开发板预置样例启动了。

Or copy and paste one of these URLs:
http://192.168.137.100:8888/lab?token=696173ee0cbed331a0e360bf5a2b851cdf81dde0850fce7d
http://127.0.0.1:8888/lab?token=696173ee0cbed331a0e360bf5a2b851cdf81dde0850fce7d

将 http://192.168.137.100:8888/lab?token=696173ee0cbed331a0e360bf5a2b851cdf81dde0850fce7d 那行，复制到本地电脑的浏览器中。（token后面的取值，会每次不一样，不要复制此处的样例）

【说明】：不是复制 http://127.0.0.1:8888 那行。127.0.0.1 表示本机，本地电脑并没有启动什么样例的服务端。192.168.137.100（开发板）上，才是启动了样例的服务端。
