Hi all,

I'm trying to port linuxppc_2_4_devel to Xilinx ML403. I want to use
UartLite instead of Uart 16550. What changes should I do?

I have disabled "Standard/generic (8250/16550 and compatible UARTs) serial
support"
and enabled "Xilinx UART Lite" & "Console on UART Lite port" in character
devices.
And the initial kernel command string is changed to "console=ttl0
console=ttyS0,9600 ip=off root=/dev/xsysace/disc0/part3 rw".

The kernel boot log dosen't mention any serial device and it hangs up until
"System started." There is no login prompt.

My /etc/inittab is :

::sysinit:/etc/init.d/rcS
#::askfirst:-/bin/sh
::ctrlaltdel:/sbin/reboot
::shutdown:/sbin/swapoff -a
::shutdown:/bin/umount -a -r
::restart:/sbin/init
::respawn:/sbin/getty 9600 tts/0


What else should I do?
Thank you!

Qichen
