This is on Freescales code base on the 5485 right?
(That is an old kernel...)

Arnon, did you resolve the problem? Because I bump into the same one.
Another question - how do I specify configuration file for busybox syslogd?

I think it would be better you search in the micro-kernel area, anyway
20Kbytes is really a great challenge

I am using the serial.c character driver on an IXP425 system
(2.4.27 kernel).
The CTS/RTS flow control seems to be broken if you are talking to
a device with a small buffer. The IXP driver continues to fill the
IXP UART buffer until it fills. The other device, a printer, drops
CTS as

Last time i saw this message it was related with the SDRAM physical bus.
We have also a custom system-application around the MCF5282, i was stuck about
this stuff along one month (not fully time of course i couldn't writing right
now) but our case was quite quite erratic so hard to sample.
Hi
I'm using Linux Kernel 2.6.10 for Coldfire 5485 in an embedded application.
I developped my own device-driver (Profibus), working on the internal
UART of the coldfire.
This Driver produces heavy hard-interrupt und soft-irq load, because
UART Data is received and transmitted with 93750 bit/s.
