    现象: 串口一直输出乱码

    [root@luckfox root]# ls /dev | grep ttyS
    ttyS1
    系统中有ttyS1
    连接68(TX)/69(RX) GND

    串口部分截取:

    您好，首先可以查看下波特率是否正确（115200），其次同时请检测一下系统是否可以正常运行（使用ADB），排除有硬件可能出现的问题，如果有硬件问题，可以尝试更换串口调试工具解决。

    [root@luckfox etc]# stty -F /dev/ttyS1
    speed 9600 baud; line = 0;
    intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
    eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;
    werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;
    -brkint -imaxbel
    [root@luckfox etc]#

    串口工具连接也是9600, 不是115200, 并没有启动任何程序, 但是串口在输出, 另外ttyS1的引脚连接正确吗

    你使用的是CP2102串口工具吗？
