Subject: [openrisc] Updated OpenRISC toolchain instructions
Hi, JeremyThank you for your help
Actually I don't know much about linux system
My current project is work under a CenOS5 linux system
When I type man tgetent
It replies:
curs_termcap(3X)
curs_termcap(3X)
NAME
tgetent, tgetflag, tgetnum, tgetstr, tgoto, tputs - direct
curses interface to the
terminfo capability database
SYNOPSIS
#include <curses.h>
#include <term.h>
extern char PC;
extern char * UP;
extern char * BC;
extern unsigned ospeed;
int tgetent(char *bp, const char *name);
int tgetflag(char *id);
int tgetnum(char *id);
char *tgetstr(char *id, char **area);
char *tgoto(const char *cap, int col, int row);
int tputs(const char *str, int affcnt, int (*putc)(int));
DESCRIPTION
These routines are included as a conversion aid for programs
that use the termcap
library. Their parameters are the same and the routines
are emulated using the
terminfo database. Thus, they can only be used to query
the capabilities of
entries for which a terminfo entry has been compiled.
The tgetent routine loads the entry for name. It returns 1 on
success, 0 if there
is no such entry, and -1 if the terminfo database could not be
found. The emula-
tion ignores the buffer pointer bp.
The tgetflag routine gets the boolean entry for id, or zero if
it is not available.
The tgetnum routine gets the numeric entry for id, or -1 if it
is not available.
As you know MOF has sent out a new toolchain for OR1200
I have tested it to simulate the linux system
However, it will not show the /dev/ttyS0: 'etc/init.d/rcS' as you
discribe at your AN.
It only show that:
RAMDISK: ext2 filesystem found at block 0
RAMDISK: Loading 2048KiB [1 disk] into ram disk... done.
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 104k freed
init started: BusyBox v1.7.5 (2008-04-26 13:18:58 EDT)
starting pid 22, tty '': '/etc/init.d/rcS'
then it will stop here and I can only quit it use ctrl+c
it shows back
Please press Enter to activate this console. (sim)
I have changed the sim.cfg to comment the section Ethernet
But if I modified the section UART change channel = "xterm:"
It can't work and shows segment fault
Thank you again
