Hi Anthony,Do you mean Centos 5? That's pretty much the same as Red Hat Enterprise
Linux, which is based on fairly modern Linux 2.6 kernels.
You have tgetent on this system (as I would expect) - this is the manual
page for it.
So the problem is something to do with how you are building GDB. Have
you already built binutils and GCC and are these cross-platform tools on
your search path? Are you trying to build GDB on the same machine, using
the same target? In other words you have earlier done something like
mkdir bd-binutils
cd bd-binutils
../binutils-2.16.1/configure --target=or32-uclinux --prefix=/opt/or32
make all install
PATH=/opt/or32:$PATH (or setenv PATH /opt/or32:$PATH)
cd ..
mkdir bd-gcc
cd bd-gcc
../gcc-3.4.4/configure --target=or32-uclinux --prefix=/opt/or32
cd ..
mkdir bd-gdb
../gdb-5.3/configure --target=or32-uclinux
This assumes you have first applied all the patches described in
Embecosm Applicaction Note 2
http://www.embecosm.com/download.html
Note that you cannot use --prefix with GDB.
Your Linux problem is with the UART setting in the simulator. The serial
driver doesn't seem to be able to find a terminal. What setting do you
have in the UART section of your sim.cfg? Are you using the Or1ksim
0.2.0 and have you applied the patches from the above?
HTH,
Jeremy

Hi, Jeremy
Thank 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
