工作原因,要调试chip pro的片子,需要在Ubuntu上连接usb-serial的TTL线,芯片是PL2303

步骤如下:

连接usb到ubuntu机器

查看usb设备

dmesg|grep tty  
[    0.000000] console [tty0] enabled
[    0.601118] 00:05: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
[ 2021.783234] usb 3-8: pl2303 converter now attached to ttyUSB0
[ 2037.443963] pl2303 ttyUSB0: pl2303 converter now disconnected from ttyUSB0
[ 2095.632907] usb 3-8: pl2303 converter now attached to ttyUSB0

看到USB设备是ttyUSB0

配置minicom

sudo minicom -s  
go to "Serial port setup" and change the first line to /dev/ttyUSB0.  

找到"Serial port setup",把第一行变为:/dev/ttyUSB0

然后保存,"Save setup as dfl"

重新进入minicom,就可以了

sudo minicom
