Re: [ts-7000] Re: Serial port TS-SER4 problem [SOLVED]

Dear all,

I'm trying to connect a PC shell serial emulator (putty) to the COM2 connector of the TS 7880 board and I don't success. I have checked all the configuration parameters and the mailing list mesages, tried all I have thought and it is like COM2 doesn't exist!!! I copy some chekings I have done:

ls -l /dev

-rw-r--r-- 1 root root         5 Sep  1 02:26 ttAM1
-rw-r--r-- 1 root root         5 Sep  1 02:26 ttAm1
crw-rw-rw- 1 root tty     5,   0 Feb 18  2009 tty
crw------- 1 root tty     4,   0 Aug 31 03:43 tty0
crw------- 1 root root    4,   1 Sep  1 01:07 tty1
crw------- 1 root root    4,   2 Sep  1 01:07 tty2
crw------- 1 root root    4,   3 Sep  1 01:07 tty3
crw------- 1 root root    4,   4 Sep  1 01:07 tty4
crw------- 1 root root    4,   5 Sep  1 01:07 tty5
crw------- 1 root root    4,   6 Sep  1 01:07 tty6
crw------- 1 root tty     4,   7 Feb 18  2009 tty7
crw------- 1 root tty     4,   8 Sep  1 02:58 tty8
crw------- 1 root tty     4,   9 Feb 18  2009 tty9
crwxr-xr-x 1 root root  204,  16 Mar 16  2006 ttyAM0
-rw-r--r-- 1 root root         5 Sep  1 02:35 ttyAM1
-rw-r--r-- 1 root root         5 Sep  1 02:35 ttyAS1
crw------- 1 root tty     4,  64 Sep  1 03:17 ttyS0
-rwxrwxrwx 1 root root        34 Sep  1 02:58 ttyS1

So it seems ttyS1 ie COM2 exists....

ps aux

root       715  0.0  0.9   2948  1208 ttyS0    Ss   03:08   0:00 /bin/login --
root       716  0.0  1.2   2956  1544 ttyS0    S    03:08   0:00 -bash
www-data   720  0.0  1.6  14228  2064 ?        S    03:08   0:00 /usr/sbin/apach
www-data   721  0.0  1.9 235648  2528 ?        Sl   03:08   0:00 /usr/sbin/apach
www-data   723  0.0  1.9 235648  2536 ?        Sl   03:08   0:00 /usr/sbin/apach
root       786  0.0  0.7   2476   936 ttyS0    R+   03:19   0:00 ps aux

So it seems that console is in ttyS0 ie COM1

nano /etc/inittab

#1:2345:respawn:/sbin/getty 38400 tty1
#2:23:respawn:/sbin/getty 38400 tty2
#3:23:respawn:/sbin/getty 38400 tty3
#4:23:respawn:/sbin/getty 38400 tty4
#5:23:respawn:/sbin/getty 38400 tty5
#6:23:respawn:/sbin/getty 38400 tty6

T0:23:respawn:/sbin/getty -L ttyS0 115200 vt100
#T1:23:respawn:/sbin/getty -L ttyS1 115200 vt100

So it seems that console is in ttyS0 and ttyS1 is free!!

If I do: ts7800:~# echo hola > /dev/ttyS0 It prints hola in ttyS0 (just where I am ie my shell serial emulator) so it seems that ttyS0 is console.

If I do:

ts7800:~# echo hola > /dev/ttyS1
ts7800:~# echo hola > /dev/ttyAM1
ts7800:~# echo hola > /dev/ttyAS1

nothing!!!!

ts7800:~# echo hola > /dev/ttyAM0  
-bash: /dev/ttyAM0: No such device or address  It doesn't exist...

As you can see it is like COM2 doesn't exist!!!!

I have checked serial bus cable and it is ok.... (red line just on the board dot) I am using TS manufactured cable.... so....

I am lost..... I have no more ideas....

Would you be so gratefull to help me with this???

thanks!!

Asunto: [ts-7000] Re: Serial port TS-SER4 problem [SOLVED]

 

The correct settings for a SER4 running on a TS7260 are

setserial /dev/tts/4 uart 16550A port 0x89c003a8 irq 33
setserial /dev/tts/5 uart 16550A port 0x89c002a8 irq 33
cd /dev/tts
mknod 2 c 4 66
setserial /dev/tts/2 uart 16550A port 0x89c003a0 irq 33
mknod 2 c 4 67
setserial /dev/tts/7 uart 16550A port 0x89c002a0 irq 33

PC104-IRQ6 is IRQ33 on the SBC
IRQ mapping: (PC104 -> Linux)
5->22
6->33
7->40
