u-boot-2011.09在ST2410上的移植之在RAM中运行

作者：boarmy

u-boot版本：u-boot-2011.09

运行环境：Window7  Vmware workstation7.1   CentOS6.0  
交叉编译环境：Arm-linux-gcc-4.3.2 with EABI

硬件环境：

ST2410X开发板（CPU：S3C2410X，64M SDRAM: 2片HY57V561620FTP-H，2M norflash: 39VF1601，64M nandflash:K9F1208U0M，网卡：cs8900a）

移植时间：2011.10.27  
源码下载地址：[ftp://ftp.denx.de/pub/u-boot/u-boot-2011.09.tar.bz2][ftp_ftp.denx.de_pub_u-boot_u-boot-2011.09.tar.bz2]

使用JLink间接烧写S3C2410、S3C2440开发板Nor、Nand Flash的方法：[http://www.ourdev.cn/bbs/bbs\_content\_all.jsp?bbs\_sn=3228953][http_www.ourdev.cn_bbs_bbs_content_all.jsp_bbs_sn_3228953]

一、创建板子文件夹和配置文件

1、解压源码包并进入源码目录

\[just@just study\]$ tar jxvf u-boot-2011.09.tar.bz2

\[just@just study\]$ cd u-boot-2011.09

\[just@just u-boot-2011.09\]$

2、在boards.cfg中的smdk2410后加入

\[just@just u-boot-2011.09\]$ vim boards.cfg //在旧版本中是直接在当前目录下Makefile文件中添加的

smdk2410               arm         arm920t     -                   samsung        s3c24x0

后增加一行

mutes2410                 arm         arm920t     -                   samsung        s3c24x0

st2410\_config :       unconfig

@$(MKCONFIG) $(@:\_config=) arm arm920t st2410 NULL s3c24x0我把我的板子起名叫st2410，可以依自己的喜好修改，注意＠前用tab键空格。

各项的意思如下:

mutes2410:    开发板的目标板型号(BOARD)，对应于board/samsung/mutes2410目录。

arm:        CPU的架构(ARCH)

arm920t:    CPU的类型(CPU)，其对应于cpu/arm920t子目录。

\- ：开发板名称，没有就用‘－’表示

samsung:       开发者/或经销商(vender)。

s3c24x0:    片上系统(SOC)。

最后为Options项，也可不填写

3、建立board/samsung/mutes2410目录，拷贝board/samsung/smdk2410下的文件到board/samsung/mutes2410目录，将smdk2410.c更名为mutes2410.c  //这里比版本多了一级目录samsung

\[just@just u-boot-2011.09\]$ cp -ar board/samsung/smdk2410 board/samsung/mutes2410

mv board/samsung/mutes2410/smdk2410.c board/samsung/mutes2410/mutes2410.c

4、在board/samsung/mutes2410/Makefile中，如下修改(因为前面将smdk2410.c文件改名为mutes2410.c了)：

COBJS:= smdk2410.o   //在新版本中没有flash.o了

改为：

COBJS:= mutes2410.o

5、cp include/configs/smdk2410.h include/configs/mutes2410.h

首先将mutes2410.h中的

131 \#define CONFIG\_SYS\_PROMPT       "SMDK2410 \# "  //早期版本为CFG\_PROMPT

修改为

131 \#define CONFIG\_SYS\_PROMPT       "MUTES2410 \# "

6、测试编译能否成功：

\[just@just u-boot-2011.09\]$ make mutes2410\_config  
awk '(NF && $1 !~ /^\#/) \{ print $1 ": " $1 "\_config; $(MAKE)" \}' boards.cfg > .boards.depend  
Configuring for mutes2410 board...

\[just@just u-boot-2011.09\]$ make  
Generating include/autoconf.mk  
Generating include/autoconf.mk.dep  
arm-linux-gcc -DDO\_DEPS\_ONLY \\

。。。。。。。。。。。。。。。  
然后会生成二进制文件u-boot.bin，这个时候把程序放到开发板上是运行不了的，因为通过tftp下载的程序，它会指定下载地址，然后从指定下载位置运行，而u-boot默认代码地址为0。

下面修改相关文件，开启调试配置

1）、修改u-boot默认代码地址为0x33e00000（st2410的SDRAM空间是0x30000000~0x34000000，共64M），然后修改mutes2410.h：

vim include/configs/mutes2410.h

将

\#define CONFIG\_SYS\_TEXT\_BASE    0x0

修改为

\#define CONFIG\_SYS\_TEXT\_BASE    0x33e00000

2）、在mutes2410.h文件最后\#endif前一行添加下面一行

\#define CONFIG\_SKIP\_LOWLEVEL\_INIT

CONFIG\_SKIP\_LOWLEVEL\_INIT这个宏用于cpu/arm920t/start.S里，主要是对CPU和存储控制器的初始化，因为我要在RAM中运行，所以调试阶段跳过初始化。

然后重新生成u-boot.bin，通过tftp将uboot.bin下载到开发板运行了，当然运行会出错的。

ST2410 \# tftp 0x32000000 u-boot.bin  
TFTP from server 192.168.1.91; our IP address is 192.168.1.200

U-Boot 2011.09 (Oct 27 2011 - 18:42:31)

DRAM:  64 MiB  
WARNING: Caches not enabled  
Flash: \*\*\* failed \*\*\*  
\#\#\# ERROR \#\#\# Please RESET the board \#\#\#

运行到这里死了。从串口输出信息可以看到u-boot-2011.09默认是不支持39VF1601的norflash，在后面我们先去掉对norflash的支持，先让它只在内存运行。

3）、去掉对norflash、网卡的支持

在include/configs/mutes2410.h文件中可以看到

54 /\*  
 55  \* Hardware drivers  
 56  \*/  
 57 \#define CONFIG\_NET\_MULTI  
 58 \#define CONFIG\_CS8900           /\* we have a CS8900 on-board \*/  
 59 \#define CONFIG\_CS8900\_BASE      0x19000300  
 60 \#define CONFIG\_CS8900\_BUS16     /\* the Linux driver does accesses as shorts \*/

我们注释掉第58行

在include/configs/mutes2410.h文件中找到“FLASH and environment organization”项，可以看到

179 /\*-----------------------------------------------------------------------  
180  \* FLASH and environment organization  
181  \*/  
182  
183 \#define CONFIG\_SYS\_FLASH\_CFI  
184 \#define CONFIG\_FLASH\_CFI\_DRIVER  
185 \#define CONFIG\_FLASH\_CFI\_LEGACY  
186 \#define CONFIG\_SYS\_FLASH\_LEGACY\_512Kx16  
187 \#define CONFIG\_FLASH\_SHOW\_PROGRESS      45  
188  
189 \#define CONFIG\_SYS\_MAX\_FLASH\_BANKS      1  
190 \#define CONFIG\_SYS\_FLASH\_BANKS\_LIST     \{ CONFIG\_SYS\_FLASH\_BASE \}  
191 \#define CONFIG\_SYS\_MAX\_FLASH\_SECT       (19)  
192  
193 \#define CONFIG\_ENV\_ADDR                 (CONFIG\_SYS\_FLASH\_BASE + 0x070000)  
194 \#define CONFIG\_ENV\_IS\_IN\_FLASH  
195 \#define CONFIG\_ENV\_SIZE                 0x10000  
196 /\* allow to overwrite serial and ethaddr \*/  
197 \#define CONFIG\_ENV\_OVERWRITE

我们注释掉第183到194行，在后面添加宏定义\#define CONFIG\_SYS\_NO\_FLASH  
及加上宏定义\#undef CONFIG\_CMD\_IMLS

CONFIG\_CMD\_IMLS是在include/config\_cmd\_all.h中定义的，这里要把它取消掉，否则将出现如下错误：

In file included from cmd\_bootm.c:35:  
/home/just/study/u-boot-2011.09/include/environment.h:152: error: 'CONFIG\_ENV\_SIZE' undeclared here (not in a function)

make\[1\]: Leaving directory \`/home/just/study/u-boot-2011.09/common'  
make: \*\*\* \[common/libcommon.o\] 错误 2

取消宏定义后就不会出现了

修改后如下：

183 /\*\#define CONFIG\_SYS\_FLASH\_CFI  
184 \#define CONFIG\_FLASH\_CFI\_DRIVER  
185 \#define CONFIG\_FLASH\_CFI\_LEGACY  
186 \#define CONFIG\_SYS\_FLASH\_LEGACY\_512Kx16  
187 \#define CONFIG\_FLASH\_SHOW\_PROGRESS      45  
188  
189 \#define CONFIG\_SYS\_MAX\_FLASH\_BANKS      1  
190 \#define CONFIG\_SYS\_FLASH\_BANKS\_LIST     \{ CONFIG\_SYS\_FLASH\_BASE \}  
191 \#define CONFIG\_SYS\_MAX\_FLASH\_SECT       (19)  
192  
193 \#define CONFIG\_ENV\_ADDR                 (CONFIG\_SYS\_FLASH\_BASE + 0x070000)  
194 \#define CONFIG\_ENV\_IS\_IN\_FLASH\*/  
195  
196 \#define CONFIG\_SYS\_NO\_FLASH  
197 \#undef CONFIG\_CMD\_IMLS  
198 \#define CONFIG\_ENV\_ADDR                 (PHYS\_SDRAM\_1)  
199 \#define CONFIG\_ENV\_IS\_IN\_NVRAM  
200 \#define CONFIG\_ENV\_SIZE                 0x10000  
201 /\* allow to overwrite serial and ethaddr \*/  
202 \#define CONFIG\_ENV\_OVERWRITE

因为在RAM中运行，环境参数也要做相应修改，如198,199行。默认环境参数是在flash中的。

修改后编译出错如下：

mutes2410.c:149: error: expected declaration specifiers or '...' before 'flash\_info\_t'  
mutes2410.c: In function 'board\_flash\_get\_legacy':  
mutes2410.c:151: error: 'info' undeclared (first use in this function)  
mutes2410.c:151: error: (Each undeclared identifier is reported only once  
mutes2410.c:151: error: for each function it appears in.)  
mutes2410.c:151: error: 'FLASH\_CFI\_16BIT' undeclared (first use in this function)  
mutes2410.c:152: error: 'FLASH\_CFI\_BY16' undeclared (first use in this function)  
mutes2410.c:153: error: 'FLASH\_CFI\_X16' undeclared (first use in this function)

在mutes2410.h中我已经添加了CONFIG\_SYS\_NO\_FLASH并取消了CONFIG\_SYS\_FLASH\_CFI的宏定义不知道为什么新版u-boot的board/samsung/mutes2410/mutes2410.c文件中对board\_flash\_get\_legacy函数没加宏开关，在这里我们在对'board\_flash\_get\_legacy'函数添加一个宏开关如下：（添加第149和157行）

149 \#ifdef CONFIG\_SYS\_FLASH\_CFI  
150 ulong board\_flash\_get\_legacy(ulong base, int banknum, flash\_info\_t \*info)  
151 \{  
152         info->portwidth = FLASH\_CFI\_16BIT;  
153         info->chipwidth = FLASH\_CFI\_BY16;  
154         info->interface = FLASH\_CFI\_X16;  
155         return 1;  
156 \}  
157 \#endif

编译下载运行如下：

ST2410 \# tftp 0x32000000 u-boot.bin  
TFTP from server 192.168.1.91; our IP address is 192.168.1.200

ST2410 \# go 0x32000000

U-Boot 2011.09 (Oct 28 2011 - 06:51:39)

DRAM:  64 MiB  
WARNING: Caches not enabled

到这里然后自动重启了。

4）、开启u-boot打印调试信息的功能

为了查找原因，在这里我又开启了u-boot打印调试信息的功能

在mutes2410.h文件最后\#endif前一行再添加“\#define DEBUG  1  
”添加后的结果如下：

244 \#define CONFIG\_SKIP\_LOWLEVEL\_INIT  
245 \#define DEBUG  1  
246 \#endif /\* \_\_CONFIG\_H \*/

为什么添加这个宏定义，我们在include/common.h文件中可以看到以下代码

119 \#ifdef  DEBUG  
120 \#define debug(fmt,args...)      printf (fmt ,\#\#args)  
121 \#define debugX(level,fmt,args...) if (DEBUG>=level) printf(fmt,\#\#args);  
122 \#else  
123 \#define debug(fmt,args...)  
124 \#define debugX(level,fmt,args...)  
125 \#endif  /\* DEBUG \*/  
126  
127 \#ifdef DEBUG  
128 \# define \_DEBUG 1  
129 \#else  
130 \# define \_DEBUG 0  
131 \#endif

显然需要我们开启DEBUG宏定义，源码中的debug函数才生效，而要debugX函数生效，这里我定义了DEBUG为1  
保存编译下载运行如下：
