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

You don't say what you're using for a udev initscript.  Maybe you
forgot to run "udevadm trigger" after starting udevd?  It's
asynchronous, so usually you also want a "udevadm settle" afterwards.
