imx233 no /dev/ttySP0
« on: April 22, 2014, 06:28:02 PM »
Hi,

I bought the MOD-RS232 uext module for the imx233. I do not see the /dev/ttySP0 anymore. This is my /proc/tty/drivers

Code: [Select]
root@debian:/# cat /proc/tty/drivers
/dev/tty             /dev/tty        5       0 system:/dev/tty
/dev/console         /dev/console    5       1 system:console
/dev/ptmx            /dev/ptmx       5       2 system
/dev/vc/0            /dev/vc/0       4       0 system:vtmaster
ttyAM                /dev/ttyAM    204      16 serial
pty_slave            /dev/pts      136 0-1048575 pty:slave
pty_master           /dev/ptm      128 0-1048575 pty:master
unknown              /dev/tty        4 1-63 console

I am using the standard debian distribution provided on the website.
Code: [Select]
root@debian:/# uname -a
Linux debian 2.6.35.3_OLinuXinoR4 #11 PREEMPT Mon May 21 10:27:52 EEST 2012 armv5tejl GNU/Linux

Does anybody has an idea why the /dev/ttySP0 serial device is not displayed for the uext module? Now I can not use the serial module in any applications.

Thx
Peter

Can be closed. Fixed myself. It is just strange that the standard debian kernel does not have the proper drivers.
