Subject: trouble in installing udev on arm
Date: Wed, 29 Jul 2009 06:42:14 +0000 [thread overview]
Message-ID: <1248868903.9330.3.camel@saurabh> (raw)
Hi all,
I'm working on an arm board with pxa270 processor. I have cross compiled
and installed udev on this board.
I'll attach the log of the udevadm monitor when i attacha usb stick.
---------------------------------------------------------------------------------------------
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

This proves that udev is working.
My board has 5 serial ports. I have deleted all entries of ttyS* from
the /dev directory.
Also i have the 50-default rules file in /etc/udev and /lib/udev.
But still when i reboot, no /dev/ttyS devices are creates. Why is that?
Any help will be appreciated.
Thanks in advance,
Saurabh
