开发板:     tq2440

工具:       Win7 + VMware + Debian6

U-boot版本: u-boot-2015.01

Linux版本:  天嵌自带的 linux-2.6.30.4

GCC版本:     gcc version 4.3.3 (Sourcery G++ Lite 2009q1-176)

之前由于移植过u-boot-2014.04到tq2440上,现在移植u-boot-2015.01的时候就不说那么详细了,因为之前已经说的很详细了,现在简略移植一下。

在移植的时候,基本上是参考移植u-boot-2014.04时写的文档,可以到这里下载:

一、 U-boot 1.2.0移植
移植环境:VMware5.5.2+RedHat9
开发板:SKY_2440B_V5.0或者V3.0
编译器:cross3.2(下载地址)
Uboot:u-boot-1.2.0(下载地址:http://www.linuxidc.com/Linux/2011-07/38897.htm)
先说明一下,uboot的移植参照http://www.linuxidc.com/Linux/2012-04/59294.htm
做的。
所下面写的移植过程,很多都是从blog上copy过来的,有不同的地方,我会另外指出。

首先到
http://www.linuxidc.com/Linux/2011-07/38897.htm 下载u-boot-2014.04.tar.bz2

首先说明一下u-boot-2015.01跟之前版本的差别


u-boot-2015.01.tar.bz2

下面是解压后得到的文件:

可以看到目录内容跟u-boot-2014.04不同了,下面是u-boot-2014.04的顶层目录内容:

其中最不同的就是我们所熟悉的在u-boot-2014.04中的boards.cfg和mkconfig没有了,而同时又在u-boot-2015.01的顶层目录下多出了一个configs目录,还有一个Kconfig文件(这不是Linux内核所特有的吗?),可以看到u-boot一直在学习Linux内核的配置和编译方法。

在configs目录下有很多默认的配置文件:

在Linux的arch/arm/configs下面也有很多默认的配置文件,Linux内核在配置的时候可以使用
make xxx_defconfig 来配置,

看样子,u-boot也可以使用make xxx_defconfig,Linux内核还可以使用make
menuconfig来配置,u-boot也可以使用make
menuconfig来配置,下面我们用smdk2410为例实验一下:

在u-boot-2015.01的configs目录下有一个叫做smd2410_defconfig的配置文件,那么执行
make smd2410_defconfig

然后我们再执行make menuconfig试试:

果然如此。

我们选择的是smdk2410的配置文件,在这里体现出来:

然后就可以编译了, 直接执行 make 即可,刚开始会报错:

原因是我们没有指定交叉编译工具链的名字,修改顶层的Makefile即可:

然后再执行make就可以编译成功。

在以前的u-boot配置是总是有什么ARCH、CPU、BOARD和SOC之类的变量,同时编译完成后会在include下生成一个叫做config.mk的文件,其中对这几个变量赋值了,如:

但是在u-boot-2015.01编译完成后,在include下面却没有config.mk了,只有autoconf.mk了,那它是怎么做的呢?

在u-boot-2015.01中执行完make
smdk2410_defconfig后,会在顶层目录中生成一个.config文件,我们大致看一下其中的内容:

可以看到,在.config中还是有ARCH、CPU、SOC以及BOARD之类的配置项,在顶层目录下的config.mk中会使用.config中的配置:

在arch/Kconfig中对这几个配置进行了说明:

config SYS_ARCH 
    string           
    help           
      This option should contain the architecture name to build the           
      appropriate arch/<CONFIG_SYS_ARCH> directory.           
      All the architectures should specify this option correctly.
config SYS_CPU          
    string           
    help           
      This option should contain the CPU name to build the correct           
      arch/<CONFIG_SYS_ARCH>/cpu/<CONFIG_SYS_CPU> directory.
      This is optional.  For those targets without the CPU directory,          
      leave this option empty.
config SYS_SOC          
    string           
    help           
      This option should contain the SoC name to build the directory           
      arch/<CONFIG_SYS_ARCH>/cpu/<CONFIG_SYS_CPU>/<CONFIG_SYS_SOC>.
      This is optional.  For those targets without the SoC directory,          
      leave this option empty.
config SYS_VENDOR          
    string           
    help           
      This option should contain the vendor name of the target board.           
      If it is set and           
      board/<CONFIG_SYS_VENDOR>/common/Makefile exists, the vendor common           
      directory is compiled.           
      If CONFIG_SYS_BOARD is also set, the sources under           
      board/<CONFIG_SYS_VENDOR>/<CONFIG_SYS_BOARD> directory are compiled.
      This is optional.  For those targets without the vendor directory,          
      leave this option empty.
config SYS_BOARD          
    string           
    help           
      This option should contain the name of the target board.           
      If it is set, either board/<CONFIG_SYS_VENDOR>/<CONFIG_SYS_BOARD>              
      or board/<CONFIG_SYS_BOARD> directory is compiled depending on             
      whether CONFIG_SYS_VENDOR is set or not.
      This is optional.  For those targets without the board directory,          
      leave this option empty.
config SYS_CONFIG_NAME            
    string             
    help             
      This option should contain the base name of board header file.             
      The header file include/configs/<CONFIG_SYS_CONFIG_NAME>.h              
      should be included from include/config.h.        

同时在arch/Kconfig中又会加载其他目录下的Kconfig,如 source
“arch/arm/Kconfig”,在arch/arm/Kconfig中又会加载board目录下的Kconfig,如
source
“board/samsung/smdk2410/Kconfig”,下面我们看一下board/samsung/smdk2410/Kconfig中的内容:

不错,就是在这里对.config中的那几个配置赋了值,可以看到,第一个行用TARGET_SMDK2410进行了判断,这个在arch/arm/Kconfig中:

意思是:
如果选择的是smd2410,TARGET_SMDK2410会被选择,然后board/samsung/smdk2410/Kconfig会对CONFIG_SYS_CPU、CONFIG_SYS_SOC、CONFIG_SYS_VENDOR、CONFIG_SYS_BOARD、CONFIG_SYS_CONFIG_NAME赋值:

先说到这里吧。

1.用dk登录linux主机,在dk下创建一个myboard文件夹
2.解压cross3.2:解压到/usr/local/arm/文件夹下
最好在/usr/local/arm/下创建一个3.2文件夹,把解压在arm文件夹下的文件(夹)全部移到3.2下,因为后面可能还会用到3.4.1的交叉编译器。
3.解压uboot:将uboot解压到myboard文件夹下
tar xzvf u-boot-1.2.0.tar.bz2 –C /home/dk/myboard/
4.进入uboot目录,修改Makefile
cd u-boot-1.2.0
vi Makefile
(1) 新建我的编译项
在1923行,即smdk2410_config编译项之后增加我的编译项
tekkaman2440_config    :    unconfig
        @$(MKCONFIG) $(@:_config=) arm arm920t tekkaman2440 tekkaman
s3c24x0
各项的意思如下:
arm: CPU的架构(ARCH)
arm920t: CPU的类型(CPU),其对应于cpu/arm920t子目录。
tekkaman2440:
开发板的型号(BOARD),对应于board/tekkaman/tekkaman2440目录。
tekkaman: 开发者/或经销商(vender)。
s3c24x0: 片上系统(SOC)。
(2) 修改交叉编译器路径,我用的cross3.2是在/usr/local/arm/
修改128行
CROSS_COMPILE=/usr/local/arm/3.2/bin/arm-linux-

解压后在board/samsung/目录下仍然没有2440,虽然没有直接支持2440开发板但其代码已经支持只需添加, 相关配置即可。

下面开始移植tq2440

参考u-boot-2014.04移植手册(TQ2440).pdf文档

  1. 清理一下刚才编译的垃圾

   make distclean

  1. 拷贝
  •    cp -a board/samsung/smdk2410/ board/tq2440
  •    cd board/tq2440
  •    mv smdk2410.c tq2440.c
  •    修改board/tq2440/Makefile

      修改board/tq2440/Kconfig

   修改arch/arm/Kconfig, 添加smdk2440的配置项

   修改arch/arm/Kconfig, 加载board/tq2440/Kconfig

 

  •   
    拷贝配置文件include/configs/smdk2410.h为include/configs/tq2440.h:

         cp include/configs/smdk2410.h include/configs/tq2440.h

  •    拷贝默认配置文件

         cp configs/smdk2410_defconfig configs/tq2440_defconfig

  •    修改configs/tq2440_defconfig, 在配置时我们就可以使用 make
    tq2440_defconfig了。

   将include/configs/tq2440.h中的smdk2410的信息注释掉,注意不能使用 //
这种注释方法,而必须使用 #if … #endif 或者
/**/,否则在编译链接时会出错,可能是u-boot的一个bug。

 
下面的内容就不说了,需要注意的是由于定义了宏CONFIG_SYS_GENERIC_BOARD,代码运行的过程跟以前有所不同,如在arch/arm/lib/crt0.S中的board_init_f和board_init_r分别调用的是common/board_f.c中的board_init_f和common/board_r.c中的board_init_r。

下面是patch的下载地址,目前仅支持norflash和dm9000,还不支持nandflash等(可以参考u-boot-2014.04移植手册完成)。

通过将天嵌自带的内核uImage通过tftp下载到内存的0x30008000地址处,然后设置bootargs为”noinitrd
root=/dev/mtdblock2 init=/linuxrc
console=ttySAC0″,然后设置machid为a8,使用bootm
0x30008000可以正确的启动内核:
