【转】u-boot在s3c2410开发板上移植（NAND Flash Boot）过程收藏

1）u-boot版本1.1.3，gcc version 3.3.3 (DENX ELDK 3.1.1 3.3.3-9)

2）在Makefile中加入
bks2410_config : unconfig
 @./mkconfig $(@:_config=) arm arm920t bks2410 NULL s3c24x0
我把我的板子起名叫bks2410，可以依自己的喜好修改

3）建立board/bks2410目录，拷贝board/smdk2410下的文件到board/bks2410目录，将smdk2410.c更名为bks2410.c

4）cp include/configs/smdk2410.h include/configs/bks2410.h

5）将arm-linux-gcc的目录加入到PATH环境变量中，我的是目录/opt/eldk/usr/bin:/opt/eldk/bin

6）测试编译能否成功：
make bks2410_config
make all ARCH=arm
生成u-boot.bin就OK了

7）依照你自己开发板的内存地址分配情况修改board/bks2410/memsetup.S文件，我的程序：
#include <config.h>
#include <version.h>

#define BWSCON 0x48000000

/* BWSCON */
#define DW8    (0x0)
#define DW16    (0x1)
#define DW32    (0x2)
#define WAIT    (0x1<<2)
#define UBLB    (0x1<<3)

#define B1_BWSCON    (DW32)
#define B2_BWSCON    (DW16)
#define B3_BWSCON    (DW16 + WAIT + UBLB)
#define B4_BWSCON    (DW16)
#define B5_BWSCON    (DW16)
#define B6_BWSCON    (DW32)
#define B7_BWSCON    (DW32)

/* BANK0CON */
#if 0
#define B0_Tacs    0x0 /*  0clk */
#define B0_Tcos    0x0 /*  0clk */
#define B0_Tacc    0x7 /* 14clk */
#define B0_Tcoh    0x0 /*  0clk */
#define B0_Tah    0x0 /*  0clk */
#define B0_Tacp    0x0
#define B0_PMC    0x0 /* normal */

【转】Ether Types

Ether Types (last updated 2008-09-09) NOTE: Please see [RFC5342] for current information and registration procedures. This registry will be revised soon and will be replaced with up-to-date information. Many of the networks of all classes are Ethernets (10Mb) or Experimental Ethernets (3Mb). These systems use a message "type" field in much the same way the ARPANET uses the "link" field. If you need an Ether Type, contact: IEEE Registration Authority IEEE Standards Department 445 Hoes Lane Piscataway, NJ 08854 Phone +1 732 562 3813 Fax: +1 732 562 1571 Email: <ieee-registration-authority& ieee.org > http://standards.ieee.org/regauth/index.html The following list of EtherTypes is contributed unverified information from various sources. Another list of EtherTypes is maintained by Michael A. Patton and is accessible at: <URL: http://www.cavebear.com/CaveBear/Ethernet/ > <URL: ftp://ftp.cavebear.com/pub/Ethernet-codes > Assign...

【转】udp编程实例

UDP通讯实例 2008-04-29 15:30:05 / 个人分类： linux C编程 UDP协议的几点好处： 1.UDP不要求保持一个连接； 2.UDP没有因接收方认可收到数据包（或者当数据包没有正确抵达而自动重传）而带来的开销； 3.设计UDP的目的是用于短应用和控制信息； 4.在一个数据包接一个数据包的基础上，UDP要求的 网络 带宽比TCP更小。 UDP的几个缺点： 1.程序员必须创建代码检测传输错误并进行重传（如果应用程序要求这样做）； 2.程序员必须把大数据包分片。 code： <1> /* * sender.c--UDP protocol example */ #include <stdio.h> #include <stdlib.h> #include <string.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> #include <netdb.h> int port = 6789; int main() {     int socket_descrīptor;     int iter = 0;     char buf[80];     struct sockaddr_in address;     /* Initialize socket address structure for Interner Protocols */     bzero(&address, sizeof(address)); // empty data structure     address.sin_family = AF_INET;     address.sin_addr.s_addr = inet_addr("127.0.0.1");     address...
