【电鱼派试用】+ 启动电鱼派的 Linux 系统

gurouhu1

紧接上文，本节跟大家介绍如何启动电鱼派的 Linux 系统
1、安装超级终端
超级终端为SecureCRT，安装比较简单，不再赘述了。
2、安装串口驱动
一、如图所示，将串口线连接好，插上USB

二、打开设备管理器，因为我的电脑已经转过驱动了，可以看到驱动已经安装，如图：

三、打开串口终端，设置相关参数如图：

3、给开发板上电
打印log如图：

从打印log可以看出系统的一些基本配置情况，如网口设置为动态获取IP等。

4、登录系统
登录名为：root,无密码

5、查看系统信息
一、查看系统内核版本

1. root@am335x-evm:~# uname -a
   
2. Linux am335x-evm 3.2.0 #59 Mon Nov 7 22:29:44 EST 2016 armv7l GNU/Linux

复制代码

二、查看系统内存使用情况
查看系统内存使用情况，使用#free 命令：
DRAM 为 128M,内存使用情况如下所示:

1. root@am335x-evm:~# free
   
2.              total         used         free       shared      buffers
   
3. Mem:        122880        17428       105452            0         1000
   
4. -/+ buffers:              16428       106452
   
5. Swap:            0            0            0

复制代码

三、查看系统磁盘使用情况

1. root@am335x-evm:~# df
   
2. Filesystem           1K-blocks      Used Available Use% Mounted on
   
3. /dev/root              7558400    191992   6982456   3% /
   
4. tmpfs                       40         0        40   0% /mnt/.psplash
   
5. none                     61440       148     61292   0% /dev
   
6. tmpfs                    16384        60     16324   0% /var/volatile
   
7. tmpfs                    61440         0     61440   0% /dev/shm
   
8. tmpfs                    16384         0     16384   0% /media/ram

复制代码

四、查看 CPU 信息

1. root@am335x-evm:~# cat /proc/cpuinfo
   
2. Processor       : ARMv7 Processor rev 2 (v7l)
   
3. BogoMIPS        : 718.02
   
4. Features        : swp half thumb fastmult vfp edsp thumbee neon vfpv3 tls
   
5. CPU implementer : 0x41
   
6. CPU architecture: 7
   
7. CPU variant     : 0x3
   
8. CPU part        : 0xc08
   
9. CPU revision    : 2
   
10. 
    
11. Hardware        : am335xevm
    
12. Revision        : 0000
    
13. Serial          : 0000000000000000

复制代码

可以看到，A8处理器是ARMv7 内核

五、查看网卡信息

1. root@am335x-evm:~# ifconfig
   
2. eth0      Link encap:Ethernet  HWaddr BC:6A:29:DB:8C:FA  
   
3.           UP BROADCAST ALLMULTI MULTICAST  MTU:1500  Metric:1
   
4.           RX packets:0 errors:0 dropped:0 overruns:0 frame:0
   
5.           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
   
6.           collisions:0 txqueuelen:1000
   
7.           RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
   
8. 
   
9. lo        Link encap:Local Loopback  
   
10.           inet addr:127.0.0.1  Mask:255.0.0.0
    
11.           UP LOOPBACK RUNNING  MTU:16436  Metric:1
    
12.           RX packets:0 errors:0 dropped:0 overruns:0 frame:0
    
13.           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
    
14.           collisions:0 txqueuelen:0
    
15.           RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

复制代码

要是想查看所有网卡信息，输入命令：

1. <blockquote>root@am335x-evm:~# ifconfig -a

复制代码

可以看出，开发板网口不只一个，但是can0还是有点不明白，据网友解疑应该是can总线
