uboot移植到6410开发板的过程及环境变量的修改
天涯海阁嵌入式linuxu boot移植到6410开发板的过程及环境变量的修改分类： uboot 2012-09-28 11:16 319人阅读 评论(0) 收藏举报一、通过U盘下载uboot.bin到开发板，U盘事先必须用飞凌光盘里的一个快速烧写工具，把mmc.bin烧写进U盘内，但是打开U盘后看不到这个文件。
然后将uboot.bin烧写进U盘。
（ps，如果要直接通过U盘将内核还有文件系统烧写进开发板里，可以直接将zImage跟cramfs文件系统拷进U盘）二、将U盘插入开发板，选择U盘启动模式，1 2 3 off ，其他on；打开终端，启动；之后就开始烧写，由于没有在U 盘内放zImage ，所以烧写的最后一行会提示not found zImage 等。
三、断开电源，选择nand flash启动：1 2 3 6 7 off，其他on；打开电源，在bootdelay计时的时候按下空格键；进入uboot的命令模式；四、查看环境变量：printenv五、修改环境变量：setenv，包括ip地址等，主要是修改bootcmd跟bootargs，我是用tftp下载uImage，用nfs挂载根文件系统：Setenv bootcmd 'tftp c0008000 uImage;bootm c0008000'（如果要设置多个，就要加上''号，如果有多个命令，在两个命令之间加;号）Setenv bootargs ‘console=ttySAC0 root=/dev/nfs nfsroot=172.22.17.20:/nfsroot/rootfsip=172.22.17.21’(consle是设置平台，nfsroot 是设置nfs的挂载地址，172.22.17.21是开发板的ip,172.22.17.20是主机的ip)都设置完再查看环境变量printenv ，如果没问题就保存：saveenv六、重启 ok**************************************************************************************************** 下面对bootargs的设置做一些介绍：bootargs是环境变量中的重中之重，甚至可以说整个环境变量都是围绕着bootargs来设置的。

更新说明：
Step4: 把开发板S2设置为SDBOOT，并插入SD卡，开机上电，即可运行Ubuntu Ubuntu系统开始启动，如下界面。
我们配置的Ubuntu系统，使用了XFCE窗口管理器，而不是
太庞大了，整个系统几乎无法运行。
进入系统之后，你可能看不到有趣的的应用程卡，并在桌面上显示出来。
这是它的一些设置菜单截图。
说明：通过SD卡运行Ubuntu系统，实际上只用到了
- uzImage : 内核文件，对于不同型号的LCD，分别有不同的内核文件(2)解压安装u-boot源代码
在工作目录/opt/FriendlyARM/mini6410/ubuntu中执行：
小一些，这样也可以烧写的更快一些。
Uboot_for_Tiny6410_移植步骤详解
Uboot_for_Tiny6410_移植步骤详解一、设计要求1.目的1)掌握U-boot剪裁编写2)掌握交叉编译环境的配置3)掌握U-boot的移植2.实现的功能1)U-boot编译成功2)移植U-boot，使系统支持从NAND FLASH启动二、设计方案1.硬件资源1)ARM处理器：ARM11芯片(SamsungS3C6410A)，基于ARM1176JZF-S核设计，运行频率533Mhz, 最高可达667Mhz2)存储器：128M DDR RAM，可升级至256M；MLC NAND Flash(2GB)3)其他资源：具有三LCD接口、4线电阻触摸屏接口、100M 标准网络接口、标准DB9 五线串口、Mini USB 2.0 接口、USB Host 1.1、3.5mm音频输入输出口、标准TV-OUT 接口、SD卡座、红外接收等常用接口；另外还引出4路TTL串口，另1 路TV-OUT、SDIO2 接口(可接SD WiFi)接口等；在板的还有蜂鸣器、I2C-EEPROM、备份电池、AD可调电阻、8 个中断式按键等。
2.软件资源1)arm-linux-gcc-4.5.1（交叉编译）2)u-boot-2010.09.tar.gzarm-linux-gcc-4.5.1-v6-vfp-20101103.tgz三、移植过程1.环境搭建1)建立交叉编译环境2)去这2 个网站随便下载都可以下载得到最新或者你想要的u-boot。

tiny6410内核移植
Tiny6410 的内核移植（拿来主义）一、开发环境宿主机: vista+VMware+ fedoral13(win7下虚拟机)编译器: 友善自带arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz开发板: tiny6410，核心板号1106 NAND 2G RAM 256M注意：移植内核时，确保引导文件为u-boot类型，否则到后面下载到开发板使会出现乱码以及不必要的错误二、移植nand_flash1 下载linux-2.6.38的源码ftp:///pub/linux/kernel/v2.6/linux-2.6.38.tar.bz22 解压#tar xvfj /mnt/ubuntu/linux-2.6.38.tar.bz2 -C .3 修改根下的Makefile#vi Makefile191行改为ARCH ?= armCROSS_COMPILE ?= arm-linux- (找到其交叉编译环境)4 生成默认配置文件#cp arch/arm/configs/s3c6400_defconfig .config（如果省略的话，后面会找不到System Type）5 修改配置项（基本配置）#make menuconfigGeneral setup->(/usr/4.5.1/bin/arm-linux-) Cross-compiler tool prefix 我将编译器解压到了/opt/Friendly/toolschain/4.5.1/bin目录（如果第三步中以修改“plier ? = arm-linux- ”此项，这步可以不作）System Type->[*] MINI6410 选上，其他的可以去掉，不确定的可以参考友善之臂的（这样编译出来的内核是可以被uboot引导的，然后是增加nand flash支持）vi arch/arm/mach-s3c64xx/mach-mini6410.c第117行struct mtd_partition mini6410_nand_part[] = {{.name = "Bootloader",.offset = 0,.size = (4 * 128 *SZ_1K),.mask_flags = MTD_CAP_NANDFLASH,},{.name = "Kernel",.offset = (4 * 128 *SZ_1K),.size = (5*SZ_1M) ,.mask_flags = MTD_CAP_NANDFLASH,},{.name = "File System",.offset = MTDPART_OFS_APPEND,.size = MTDPART_SIZ_FULL,}}; //update at 2011-8-26 经过测试发现，这里改完后根本不起作用，甚至将整个注释也无妨，估计分区已经固死在后面的s3c_nand_mlc.fo 中6 拷贝NAND FLASH驱动（将6410内核中的如下文件拷到相应的目录下）需拷贝文件：drivers/mtd/nand/s3c_nand.carch/arm/plat-samsung/include/plat/regs-nand.h 覆盖掉drivers/mtd/nand/s3c_nand_mlc.fo《s3c_nand_mlc.fo友善没有开源的一个驱动之一，所以不用研究了，拷过来就是了。
tiny6410烧写环境
1、准备SD卡uboot需要SD卡烧写器和uboot镜像下载地址为：SD卡烧写器：/detail/songlan0012/7297353sd卡uboot镜像：/detail/songlan0012/73033692、将串口转usb线硬件连接好，串口接到tiny6410开发板，usb口接到电脑，会检查到新usb硬件图一这个是串口转USB驱动没有安装，点击取消，下载安装文件：PL2303_Prolific_DriverInstaller_v110.zip（我使用的是这个硬件）。
usb转串口驱动下载地址：/detail/songlan0012/7303905安装完后在设备管理器其中查看如图（可能需要重新拔掉再插上usb接口）图二图中COM3就是了。
打开dnw（串口界面工具），下载地址：/detail/songlan0012/7297327初始状态如图：图三点击Serial Port 菜单中的Connect选项，状态如下图：图四如果如上图出现COM3，115200bps （COM3是设备管理器中的COM3可能是其他COM口编号）恭喜，至此tiny6410串口驱动安装成功。
2、制作sd卡uboot资源：需要一个大于等于4G的SD卡，格式化成FAT32格式工具：SD-Flasher.exe （SD卡烧写器）工具下载地址：/detail/songlan0012/7297353这个工具不需要安装，直接运行使用。
直接打开界面为下图：图五点击Image file to fuse输入框后面的按钮选择要烧写的superuboot镜像，镜像下载地址为：/detail/songlan0012/7303369然后点击Scan按钮，按钮左侧的显示区会显示sd卡信息，例如下图：图六这说明已经检测到了正确检测到了SD卡点击Fuse按钮烧写会出现如下图信息：图七这说明sd卡uboot烧写成功。
将sd卡插入tiny6410的sd卡插槽内，将选择sd卡或者nand启动的开关拨到SD卡启动，连接好usb转串口线，插上开发板电源线，打开DNW至图四状态，上电，DNW会显示如下图信息：图八恭喜您，sd卡中的Uboot已经启动了。

Uboot_for_mini6410_移植步骤详解
这是u-boot-2010.09 针对友善之臂MINI6410移植的最基础版本，只包含了就基本的系统引导，NAND读写，DM9000网卡等等。
但是这个足够开发的方便使用。
今后会陆续添加原先我为mini2440添加的所有功能。
但是此次移植并非我的功劳，首先基本的移植是由Alex Ling <kasimling at >完成的，你可以在这里看到他提交的补丁，但是编译后无法使用，可能是因为host系统不同，对脚本的解析不同，使得spl部分的生成出现问题,只需修改一下nand_spl目录下目标板目录的中config.mk中的PAD_TO := $(shell expr $$[$(TEXT_BASE) + 4096])即可。
DM9000的驱动没有太大的问题（修改了一点可能出现问题的地方，感谢肖工指教），但是原本的u-boot并没有调整所有SROM控制器的配置（其中包括连接DM9000所使用的bank1的总线），我使用了友善带的u-boot的参数配置了一下就好了。
一：/batch.viewlink.php?itemid=1694ftp://ftp.denx.de/pub/u-boot/去这2个网站随便下载都可以下载得到最新或者你想要的u-boot。
现在我将下载u-boot-2010-09，这个也就是最新的版本啦。
下载后把它解压，然后得到u-boot-2010-09的文件夹，然后进去，并且做下面几件事情：1：进入arch这个文件夹，把出arm外的前部文件夹删掉2：进入board这个文件夹，把除samsung外前部文件夹删掉3：进入include/configs，把除smdk6400.h外的所有文件删除。
4: 把顶层目录下有一个叫onenand_ipl的文件夹删除掉，因为没有用到。
5：进入nand_spl/board，把除samsung外全部文件删除掉。
6：再进入arch/arm/cpu文件夹，把除arm1176外其他文件夹删除掉。
