2、验证USB转串口线是否己有驱动
# 如果有usbserial，说明系统支持USB转串口
hisilicon@ubuntu:~$ lsmod | grep usbserial
usbserial 49152 1 ftdi_sio
# 插上USB转串口，确认ubuntu系统是否己识别该设备
hisilicon@ubuntu:~$ dmesg | grep ttyUSB0
[ 309.007290] usb 2-2.2: FTDI USB Serial Device converter now attached to ttyUSB0
[ 433.314450] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
hisilicon@ubuntu:~$ ll /dev | grep USB
crw-rw---- 1 root dialout 188, 0 May 29 10:43 ttyUSB0
3、配置minicom连接的端口
hisilicon@ubuntu:~$ sudo minicom -s
+-----[configuration]------+
| Filenames and paths |
| File transfer protocols |
| Serial port setup |
| Modem and dialing |
| Screen and keyboard |
| Save setup as dfl |
| Save setup as.. |
| Exit |
| Exit from Minicom |
+--------------------------+
# 选择 Serial port setup，选择修改A，并将串口设备修改为/dev/ttyUSB0，将硬件流控制改为NO，并根据实际需要修改波特率等参数，连海思使用默认115200 8N1。
# 如果不改硬件流控制设置，会出现Hit any key to stop autoboot时敲任意键没有反应，造成无法修改uboot配置
+-----------------------------------------------------------------------+
| A - Serial Device : /dev/ttyUSB0 |
| 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? |
+-----------------------------------------------------------------------+
# 修改完成后回车，选Save setup as dfl 保存
+-----[configuration]------+
| Filenames and paths |
| File transfer protocols |
| Serial port setup |
| Modem and dialing |
| Screen and keyboard |
| Save setup as dfl |

| Exit |
| Exit from Minicom |
+--------------------------+
4、启动minicom
hisilicon@ubuntu:~$ sudo minicom -w
Welcome to minicom 2.7.1
