CLE yum
Yum Repository 的使用方式:
我舉 FC5 為例:
1.到 ftp://cle.linux.org.tw/pub/fedora/yum/repos/ 目錄底下把所有的 *.repo 檔下載回去，放到 /etc/yum.repos.d/ 底下 (可以蓋掉原來的舊的設定檔)
2.相關的 RPM GPG KEYs 都可以在 ftp://cle.linux.org.tw/pub/fedora/yum/ 目錄底下找到，把 RPM-* 的檔案都下載回去，然後用 “rpm –import RPM-*” 指令來把所需的 KEYs Import 進去
3.接下來，就是 yum update、yum install
、yum remove ….
rpm --import /usr/share/doc/fedora-release-3/*GPG-KEY*
刪除/etc/yum..repos.d/livna.repo

ISDN 筆記
1.Different between ISDN BRI-S/T and BRI-U
ISDN service is typically provided using modular plugs. These plugs include a RJ45 interface (8 pin) for data equipment (called a BRI-S/T) and the other physical connection type is a two-wire, RJ11 type standard (called the BRI-U).

ARM gdb howto (轉載)
一.下载gdb-6.4.tar.gz源代码
http://ftp.gnu.org/gnu/gdb/
二．编译 GDB
#tar zxvf gdb-6.4.tar.gz
2.1 编译GDB Server
#cd gdb-6.4
#./configure --target=arm-linux --prefix=/usr/local/arm-gdb
#make
#make install // 生成/usr/local/arm-gdb/bin
2.2 编译GDB Client
#cd ./gdb/gdbserver
#export PATH=$PATH:/usr/local/arm-gdb/bin
#./configure --target=arm-linux --host=arm-linux
#vi config.h
//#define HAVA_SYS_REG_H //注释此句
#make CC=arm-linux-gcc //编译用于目标机的stub程序 生成gdbserver是GDB客户端程序，在板子上运行。
三．实战调试
1．编辑文件
# vi gdbtest.c
1 #include <stdio.h>
2
3 int
4 func(int n){
5 int sum=0, i;
6 for (i=0; i<n; i++){
7 sum += i;
8 }
9 return sum;
10 }
11
12 int
13 main(void)
14 {
15 int i;
16 long result = 0;
17 for (i=0; i<=100; i++){
18 result += i;
19 }
20
21 printf("result[1-100] = %d \n", result);
22 printf("resutl[1-225] = %d \n", func(255));
23
24 return 0;
25 }
# arm-linux-gcc -g gdbtest.c -o gdbtest // 交叉编译
2.下载文件到目标板: gdbtest和gdbserver
假设 host pc ip:192.168.1.45
board ip:192.168.1.180
将文件拷贝到目标板上：
先将gdbtest和gdbserver两个文件拷贝到主机的/tftpboot目录下
在目标板的Linux中运行：
#mount 192.168.1.108:/tftpboot /mnt/nfs
#cd /mnt/nfs
#ls
看是否有gdbtest和gdbserver两个文件。
3.运行调试
client board：
#./gdbserver 192.168.1.45:1234 gdbtest // 目标板上运行gdbtest 监听端口1234
host pc：
#cd /usr/local/arm-gdb/bin/
#copy gdbtest /usr/local/arm-gdb/bin/ // 将前面编译的文件gdbtest拷贝到此目录
#./arm-linux-gdb gdbtest
(gdb) target remote 192.168.1.180:1234 // 连接到开 发板 成功后就可以进行调试
(gdb)list or l
(gdb)break func
(gdb)break 22
(gdb)info br
(gdb)continue or c // 这里不能用 run
(gdb)next or n
(gdb)print or p result
(gdb) finish // 跳出func函数
(gdb) next
(gdb) quit
建立连接后进行gdb远程调试和gdb本地调试方法相同
