注意 CONFIG_ENV_OFFSET和 CONFIG_ENV_SIZE 的设置,不要覆盖了其他分区。
CONFIG_ENV_OFFSET是在整个存储器中的偏移地址;
CONFIG_ENV_SIZE是指其使用的大小。
命令:
loadb - load binary file over serial line (kermit mode)
loadx - load binary file over serial line (xmodem mode)
loady - load binary file over serial line (ymodem mode)
功能:以不同的协议从串口获取文件.。
格式基本都为:
load? [ off ] [ baud ]
第1个参数是下载到SDRAM的地址,如果不填,就是用默认配置:CONFIG_SYS_LOAD_ADDR
第2个参数是波特率,一般不填,用默认的115200.
在windows下的超级终端可以用这些协议发送文件,但是在ubuntu下基本只能用kermit协议。一下使用C-kermit来发送一个文件到mini2440。
[u-boot@MINI2440]# loadb ## Ready for binary (kermit) download to 0x30008000 at 115200 bps... |
上面已经启动了U-boot的kermit传输协议,这时按下 Ctrl + \ , 再按 c, 切换到C-kermit的命令行模式,输入命令:send <文件路径>,回车。

(4)网络命令
只要你的网卡驱动没问题,那么你就可以通过网络来传输文件到开发板,这可比串口快多了。你可以直接用交叉网线连接开发板和电脑,也可以用普通直连网线连接路由器,再连到电脑,不过记得配置好网络,关闭防火墙哦。
先测试网络是否通了,现在开发板使用ping 命令,看看是否可以ping通电脑:

内核引导
内核的引导步骤如下:为什么要用U-boot的mkimage工具处理内核映像zImage? 因为在用bootm命令引导内核的时候,bootm需要读取一个64字节的文件头,来获取这个内核映象所针对的CPU体系结构、OS、加载到内存中的位置、在内存中入口点的位置以及映象名等等信息。这样bootm才能为OS设置好启动环境,并跳入内核映象的入口点。而mkimage就是添加这个文件头的专用工具。具体的实现请看U-boot中bootm的源码和mkimage的源码。 |
mkimage工具的使用: 参数说明: -A 指定CPU的体系结构,可用值有:alpha、arm 、x86、ia64、mips、mips64、ppc 、s390、sh、sparc 、sparc64、m68k等 -O 指定操作系统类型,可用值有:openbsd、netbsd、freebsd、4_4bsd、linux、svr4、esix、solaris、irix、sco、dell、ncr、lynxos、vxworks、psos、qnx、u-boot、rtems、artos -T 指定映象类型,可用值有:standalone、kernel、ramdisk、multi、firmware、script、filesystem -C 指定映象压缩方式,可用值有: none 不压缩(一般使用这个,因为zImage是已经被bzip2压缩过的自解压内核) gzip 用gzip的压缩方式 bzip2 用bzip2的压缩方式 -a 指定映象在内存中的加载地址,映象下载到内存中时,要按照用mkimage制作映象时,这个参数所指定的地址值来下载 -e 指定映象运行的入口点地址,这个地址就是-a参数指定的值加上0x40(因为前面有个mkimage添加的0x40个字节的头) -n 指定映象名 -d 指定制作映象的源文件 以下是制作内核映像的命令示例: mkimage -n 'tekkaman' -A arm -O linux -T kernel -C none -a 0x30008000 -e 0x30008040 -d zImage zImage.img |
