kermit安装问题
问题:按照网友的方法安装及配置kermrc后,打完点后,没有板子的打印信息
C-Kermit>c
Connecting to /dev/ttyS0, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
问题原因:1.是自己的串口没有设置正确,因为的主板不带串口,所以就自己安装了PCI串口卡,这个串口
设置的不是ttyyS0.
使用命令察看串口信息:
dmesg | grep ttyS0
[ 0.347112] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 0.726193] 00:07: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
asp00@ubuntu:~$ dmesg | grep ttyS1
asp00@ubuntu:~$ dmesg | grep ttyS2
asp00@ubuntu:~$ dmesg | grep ttyS3
asp00@ubuntu:~$ dmesg | grep ttyS4
[ 0.726503] 0000:03:05.0: ttyS4 at I/O 0xcf00 (irq = 20) is a XScale
asp00@ubuntu:~$ dmesg | grep ttyS5
asp00@ubuntu:~$ dmesg | grep ttyS6
[ 0.748000] 0000:03:06.0: ttyS6 at I/O 0xcd00 (irq = 21) is a ST16650V2
asp00@ubuntu:~$ dmesg | grep ttyS7
[ 0.769437] 0000:03:06.1: ttyS7 at I/O 0xcc00 (irq = 22) is a ST16650V2
发现:ttyS6/7才是,自己安装的串口卡。重新设置成串口6后,有打印信息:
m :92,h:1,p:1
clkdiv:5
sys_fclk :400000000,sys_hclk:100000000,sys_pclk:50000000
