最终拿到板子了, 嵌入式开发正式开启.
板子型号 : 三星 S3C6410 基于ARM11, 指令集基于arm6指令集;
为毛不是 Cortext A9的板子;
烧写内容 : BootLoader, Linux Kernel, File System;
烧写流程 :
-- sd卡烧写u-boot并启动 : 首先将 u-boot 烧写到 sd 卡中, 使用 sd 卡的bootloader启动;
-- 擦出nand flash : 之后将开发板的闪存 nand flassh 擦除干净;
-- nand flash 烧写 u-boot : 然后将 u-boot 烧写到 nand flash 中;
-- 烧写内核 : 向nand flash 中烧写内核;
-- 烧写文件系统 : 将文件系统烧写到nand flash 中;
嵌入式开发板软件层次 : 从底层到上层 引导程序 -> Linux内核 -> 文件系统 -> 应用程序
-- 引导载入程序 : 分为两部分 硬件中的固化boot代码 和 BootLoader代码, 当中固化的boot代码可有可无, BootLoader是烧写上去的;
-- Linux内核 : 嵌入式开发板定制的内核 和 其启动參数;
-- 文件系统 : 即Linux中的文件系统;
-- 应用程序 : 即用户运行的应用程序, 应用程序 和 内核之间可能包括嵌入式的图形界面;
引导载入程序介绍 : 引导载入程序是系统上电之后运行的第一段程序;
PC机上的引导载入程序 :
-- 组成结构 : BIOS (固件程序) 和 BootLoader(GRUB等程序);
-- 运行过程 : BIOS运行硬件检測 和 资源分配, 之后将BootLoader读取到内存中, 開始运行BootLoader内容;
-- 运行作用 : 将内核读取到内存中, 跳转到内核的入口运行, 正式运行操作系统程序;
嵌入式BootLoader : BootLoader与硬件的依赖性非常强, 每一种嵌入式设备都有其相应的BootLoader引导程序, 在这里 S3C6410 板子使用的BootLoader 是 U-BOOT;
BootLoader操作模式 : 将BootLoader烧写到 nand flash 中之后, 第一次启动是靠交互模式启动的, 之后就靠子启动模式启动;
-- 自启动模式 : 系统上电之后自己主动将 BootLoader 载入到内存, 之后自己主动开启系统, 整个过程全自己主动, 用户不介入;
-- 交互模式 : BootLoader 通过串口 或者 网络从服务器上下载内核到内存中, 能够将内核写到磁盘, 或者直接进入系统, 同一时候能够从串口中接收用户命令;
BootLoader启动过程 : 分为两个阶段;
-- 第一阶段 : 初始化基本硬件, 将BootLoader载入到内存中, 设置堆栈指针, 清空BSS段;
-- 第二阶段 : 初始化本阶段用的硬件, 读取环境变量, 启动BootLoader(两种启动模式);
烧写过程须要配置 网络, tftp, nfs 三项, 配置完之后重新启动服务器;
须要设置网络ip地址 和 关闭防火墙; 假设是 redhat 系统, 还须要关闭SELinux;
设置ip地址命令 : ifcofig eth0 192.168.1.27 命令;
关闭防火墙 : sudo ufw disable 命令;
重新启动网络服务 : sudo /etc/init.d/networking restart 命令;
octopus@octopus:~$ sudo ifconfig eth0 192.168.1.27 octopus@octopus:~$ sudo ufw disable 防火墙在系统启动时自己主动禁用 octopus@octopus:~$ sudo /etc/init.d/networking restart * Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces * Reconfiguring network interfaces...
安装tftp软件 :
-- 安装tftp服务器 : sudo apt-get install tftpd 命令;
-- 安装tftp客户端 : sudo apt-get install tftp 命令;
-- 安装 xinetd : sudo apt-get install xinetd 命令;
配置 tftp : 建立 /etc/xinetd.d/tftp 文件, 使用 sudo vim /etc/xinetd.d/tftp 命令, 向文件里写入以下内容 :
service tftp { socket_type = dgram wait = yes disable = no user = root protocol = udp server = /usr/sbin/in.tftpd server_args = -s /tftpboot #log_on_success += PID HOST DURATION #log_on_failure += HOST per_source = 11 cps =100 2 flags =IPv4 }
,
创建共享文件夹 : 查看 根文件夹下 有没有 tftpboot 文件夹, 假设没有的话就创建 /tftpboot 文件夹;
-- 创建共享文件夹 : sudo mkdir /tftpboot 命令创建;
-- 改动权限 : sudo chmod -R 777 /tftpboot , 加上 -R 表示 递归将其子文件夹子文件也进行权限改动;
改动 /etc/xinetd.d 配置文件 : 保证配置文件与以下一致就可以;
# Simple configuration file for xinetd # # Some defaults, and include /etc/xinetd.d/ defaults { # Please note that you need a log_type line to be able to use log_on_success # and log_on_failure. The default is the following : # log_type = SYSLOG daemon info } includedir /etc/xinetd.d
# /etc/default/tftpd-hpa TFTP_USERNAME="tftp" TFTP_DIRECTORY="/tftpboot" TFTP_ADDRESS="0.0.0.0:69" TFTP_OPTIONS="-l -c -s"
-- 运行 service tftpd-hpa restart 命令 :
octopus@octopus:~$ service tftpd-hpa restart stop: Rejected send message, 1 matched rules; type="method_call", sender=":1.83" (uid=1000 pid=5737 comm="stop tftpd-hpa ") interface="com.ubuntu.Upstart0_6.Job" member="Stop" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init") start: Rejected send message, 1 matched rules; type="method_call", sender=":1.84" (uid=1000 pid=5734 comm="start tftpd-hpa ") interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")-- 运行 sudo /etc/init.d/xinetd reload 命令 :

The restart(8) utility is also available. xinetd stop/waiting xinetd start/running, process 5769
-- 进入tftp : 使用 tftp localhost , 进入本地的tftp服务器;
-- 下载当中的文件 : 使用 get uboot.bin 下载当中的 uboot 文件到本地文件夹, 假设文件不存在会提示 Error code 1: File not found 错误;
octopus@octopus:~$ tftp localhost tftp> get aaa Error code 1: File not found tftp> get uboot.bin tftp> quit octopus@octopus:~$ ls aaa develop icmp ndk Source Insight x86-probe 模板 图片 下载 桌面 arm-probe gcc log4c-1.2.1 programs uboot.bin 公共的 视频 文档 音乐
安装nfs服务器 : sudo apt-get install nfs-kernel-server 命令;
配置 nfs 服务 : 使用 sudo vim /etc/exports 命令配置, 将以下的内容加入到文件末尾 ;
/nfsroot *(rw,sync,no_root_squash)
-- 最终配置 :
# /etc/exports: the access control list for filesystems which may be exported # to NFS clients. See exports(5). # # Example for NFSv2 and NFSv3: # /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check) # # Example for NFSv4: # /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check) # /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check) /nfsroot *(rw,sync,no_root_squash)
-- * : 表示随意IP都能够訪问;
-- rw : 表示 能够 读 写;
-- sync : 表示 同步;
-- no_root_squash : 表示 root 用户登录不做权限检查;
创建共享文件夹 : sudo mkdir /nfsroot ;
重新启动端口映射 : sudo /etc/init.d/portmap restart ;
octopus@octopus:~$ sudo /etc/init.d/portmap restart Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service portmap restart Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the stop(8) and then start(8) utilities, e.g. stop portmap ; start portmap. The restart(8) utility is also available. portmap stop/waiting portmap start/running, process 5234

烧写位置 : 烧写的 u-boot 位于 sd卡的末端, 假设SD卡存满了数据, 就会将最后的数据破坏掉, 烧写的 u-boot 在文件系统中是看不到的;
计算位置 : 依据SD卡类型计算出 烧写 u-boot 的初始位置;
-- SD卡 : SD 卡 最后2个文件块 不能用于烧写 u-boot, 因此烧写的位置是 SD卡块大小 减去 2 再减去 u-boot 的块大小, 注意是 块 大小, 一块是 512字节;
-- SDHC卡 : SDHC 卡 最后 1026 字节不能用于烧写 u-boot, 因此烧写的位置是 SDHC卡 块大小 减去 1026, 再减去 u-boot 块大小;
将SD卡装入读卡器, 查看设备名称 : 使用 sudo fdisk -l /dev/sd* 查看sd卡大小, 推断sd卡;
-- 查找sd卡 : 使用 ls /dev/sd* 命令查找sd卡;
octopus@octopus:~$ ls /dev/sd* /dev/sda /dev/sda1 /dev/sda2 /dev/sda5 /dev/sdb /dev/sdb1-- 查看SD卡信息 : 使用 sudo fdisk -l /dev/sdb 命令, 能够看到 SD卡的块大小是 512字节, 总字节数为 1018691584 , 总块数为 1989632 块;
octopus@octopus:~$ sudo fdisk -l /dev/sdb Disk /dev/sdb: 1018 MB, 1018691584 bytes 30 heads, 29 sectors/track, 2286 cylinders, total 1989632 sectors Units = 扇区 of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 设备 启动 起点 终点 块数 Id 系统 /dev/sdb1-- 查看 SD 卡块大小 : 使用 cat /sys/block/sdb/size 命令;
octopus@octopus:~$ cat /sys/block/sdb/size 1989632
octopus@octopus:~$ ll u-boot-movi.bin -rw-r--r-- 1 octopus octopus 270336 4月 20 16:59 u-boot-movi.bin
烧写 u-boot 到 SD卡 : 将 u-boot 放到 ~ 文件夹, 进入该文件夹, 运行以下的命令 :
sudo dd if=u-boot-movi.bin of=/dev/sdb bs=512 count=528 seek=1989102
-- if : 烧写的源文件;
-- of : 要烧写的设备;
-- bs : 设备的文件块大小;
-- count : 烧写的源文件块大小;
-- seek : 烧写的sd卡的初始位置, 设立是 sd卡块大小 - 2 - 528;
须要注意的问题 :
-- 权限不够 : 须要 root 用户运行 dd 命令;
-- 仅仅读文件系统 : 将 SD卡中的 写 开关打开;
octopus@octopus:~$ dd if=u-boot-movi.bin of=/dev/sdb bs=512 count=528 seek=1989102 dd: 正在打开"/dev/sdb": 权限不够 octopus@octopus:~$ sudo dd if=u-boot-movi.bin of=/dev/sdb bs=512 count=528 seek=1989102 dd: 正在打开"/dev/sdb": 仅仅读文件系统 octopus@octopus:~$ sudo dd if=u-boot-movi.bin of=/dev/sdb bs=512 count=528 seek=1989102 记录了528+0 的读入 记录了528+0 的写出 270336字节(270 kB)已复制。0.0582359 秒。4.6 MB/秒
使用 SD 卡启动 uboot : 烧写完毕之后, 将SD卡插入开发板, 并使用 SD卡启动模式, 进入系统;
-- 权限问题 : 进入 minicom , 注意 这个也要使用 sudo minicom 运行, 须要 root 权限;
-- 载入完uboot立马中断 : 打开开发板, 注意要不停的按回车, 由于 u-boot 启动之后就会载入内核 和 系统文件, 这里我们仅仅有 u-boot, 没有kernel 会出现未知问题, 因此 不能让其继续载入;
