针对ARMSYS44B0X的minicom设置

minicom是一个串口通信程序,Linux环境下我们可以用它来完成Windows下超级终端的任务.为了使它能符合ARMSYS44B0这个特殊硬件,需要进行参数的设置.
在超级终端启动minicom
[root@localhost ~]# minicom
因为还没有进行相关参数的设置,所以我们看不到bootloader的功能项.
看到minicom的欢迎界面:

Press CTRL-A Z for help on special keys

minicom是基于窗口的,要弹出所需功能的窗口，可按下Ctrl-A,再按各功能键(a-z或A-Z).其中按[Z]进入minicom的菜单

我们可以按[O]进行minicom的参数设置,终端出现配置菜单
            ┌─────[configuration]──────┐
            │ Filenames and paths      │
            │ File transfer protocols  │
            │ Serial port setup        │
            │ Modem and dialing        │
            │ Screen and keyboard      │
            │ Save setup as dfl        │
            │ Save setup as..          │
            │ Exit  
   
使用上下方向键进行选择,回车确认,Esc退出.这里我们需要对串口参数进行修改.进入子菜单Serial port setup,修改成下面参数(原来的串口设备,波特率和硬件流控制需要修改)
    │ A -    Serial Device      : /dev/ttyS0                                │
    │ B - Lockfile Location     : /var/lock                                 │
    │ C -   Callin Program      :                                           │
    │ D -  Callout Program      :                                           │
    │ E -    Bps/Par/Bits       : 115200 8N1                                │
    │ F - Hardware Flow Control : No                                        │
    │ G - Software Flow Control : No                                        │
    │                                                                       │
    │    Change which setting?  
按Esc退回到上级菜单,选择 Save setup as df1项保存,然后退出.不需要重新启动minicom,按下开发板的复位键,出现bootloader功能项
