Hello,

Greg, thanks for Your answer.

I've put "write" in init thread in init/main.c, before /sbin/init is
started. It seems like the "write" outputs have blocked printf... which
comes from RAM disk.
User programm is:
#include<stdio.h>
#include<sys/types.h>
#include<fcntl.h>
int main (void)
{
int i,fd;

        for(i=0;i<4;i++){

        printf("--- H E L L O   W O R L D  ***  \n");

        }
fflush(NULL);

return 1;
}
========================================================
Greg, I've put put some printks to debug function sci_set_baud and 
SCSMR = 0
t = 26

I'm not sure, are these settings correct for my platform. According to
hardware manual, I have to know "operating frequency for periphelar devices"
to set SCBRR correct. Is this value showed at booting of kernel?

I'm a little bit confused about all these problems, because I had allready
working RAM disk with init, bash ...I don't see any reason for these
troubles.

I've also tried to start with new kernel 2.4.0, I've modified in
arch/sh/kernel/setup.c line for
#define COMMAND_LINE "console=ttySC1,38400" and set correct baud rate. I
cannot see any boot messages. SO I think, I have to use GDB Stub (SH-IPL+g)
to get possibility really debbuging the code


thanks for tips,

Pawel
