uboot 移植遇到的问题及解决方法(转)

http://blog.sina.com.cn/s/blog_988ec60801017iy3.html

一  在commond 

env_nand.c: In function 'saveenv':

env_nand.c:196: error: stray '#' in program

env_nand.c:196: error: expected ')' before 'define'

env_nand.c:196: error: too few arguments to function 'nand_erase'

env_nand.c:201: error: stray '#' in program

env_nand.c:201: error: expected ')' before 'define'

env_nand.c: In function 'env_relocate_spec':

env_nand.c:276: error: expected ')' before 'define'

env_nand.c:276: error: too few arguments to function 'nand_read'

make[1]: *** [env_nand.o] 错误 1

make[1]:正在离开目录 `/home/cgc/yangshanjin/u-boot-1.1.6_3/common

make: *** [common/libcommon.a] 错误 2

因此 我就把有错误的语句注释掉，即196 201 276

二  上面问题搞定，我用注释的办法 

现在 又有问题如下

解决办法 我修改办法

 修改cpu/arm920t/config.mk文件中的

 

PLATFORM_RELFLAGS += -fno-strict-aliasing  -fno-common

-ffixed-r8 \

   -msoft-float

改为

PLATFORM_RELFLAGS += -fno-strict-aliasing

-fno-common -ffixed-r8

还是一样的错误

我的参考网站http://bbs.chinaunix.net/forum.php?mod=viewthread&action=printable&tid=1938330

解决办法（成功）在顶层Makefile

把CROSS_COMPILE=…………（你的交叉编译器），改为：CROSS_COMPILE=/opt/EmbedSky /crosstools_3.4.5_softloat/gcc-3.4.5-glibc-2.3.6/arm-linux/bin/arm-linux-

就可正常编译成功。

无打印信息。参考网站http://www.armbbs.net/forum.php?mod=viewthread&tid=6442

我的修改一

在include/configs/YSJ2440.h里修改#define CONFIG_SMDK2440 1 

                                 #define  CONFIG_S3C2440  1 我已经改回来了

要不的话就会报错

修改二 在include/s3c2410.h 中添加了 #include <s3c2440.h>

我把s3c2440.h删除掉了，因为其作用是跟s3c24x0.h是一样的

今天发现configs/YSJ2440.h是应该许多预编译中变量的定义，还有s3c2410.h里包含了s3c24x0.h

 

我把YSJ2440.C board_init函数中对于s3c2410的时钟设置消去，用if(0)

我把cpu/arm920t/s3c24x0/nand_flash.c有关2410的nand_flash都注释掉

出现错误

nand_flash.c: In function `board_nand_init':

nand_flash.c:140: error: `s3c2410_nand_hwcontrol' undeclared (first use in this

function)

nand_flash.c:140: error: (Each undeclared identifier is reported only once

nand_flash.c:140: error: for each function it appears in.)

nand_flash.c:141: error: `s3c2410_nand_devready' undeclared (first use in this

function)

nand_flash.c:142: error: `s3c2410_nand_select_chip' undeclared (first use in

this function)

make[1]: *** [nand_flash.o] 错误 1

make[1]:正在离开目录 `/home/cgc/yangshanjin/u-boot-1.1.6_3/cpu/arm920t/s3c24x0'

现在复原

 

我修改了cpu/arm920t/start.S中的160行 把bl cpu_init_crit注释掉

接着修改/board/YSJ2440/config.mk中TEXT_BASE 值为0x33000000

还是搞回来

修改

relocate:

adrr0, _start

ldrr1, _TEXT_BASE

cmp     r0, r1      

beq     clear_bss

@ldr r2, _armboot_start

ldr   r1,_armboot_start

ldrr3, _bss_start

subr2, r3, r2

#if 1

bl CopyCode2Ram

#else

addr2, r0, r2

copy_loop:

ldmiar0!, {r3-r10}

stmiar1!, {r3-r10}

cmpr0, r2

ble copy_loop

#endif

#endif

 

 

我把上面的ldr r1, r1,_armboot_start     修改为mov r1,#0x33f80000  但是报错 start.S:181: Error: invalid constant -- `mov r1,#0x33f80000' 原来是精简指令问题

我改成ldr r1,=0x33f80000,就可以了 ，但是还是启动不了内核，

 

start.S 设置完中断向量表后 ， 加上这句是什么意思

.balignl 16,0xdeadbeef

 

 

#if 1 //HJ_add_start

int getc_errno = 0;

__u8 do_getc(unsigned long timeout, int *statp)

{

__u8 c, rxstat;

int do_timeout = timeout != 0;

S3C24X0_UART * const uart = S3C24X0_GetBase_UART(UART_NR);

 

getc_errno = 0;

 

while(!(uart->UTRSTAT & 0x1)) {

 

if (do_timeout) {

if (!timeout)

break;

timeout--;

}

 

}

 

if (do_timeout && timeout == 0) {

c = 0;

rxstat = -1;

} else {

c = (uart->URXH & 0xff);

rxstat = (uart->UERSTAT & 0xf);

}

 

if (rxstat) {

getc_errno = rxstat;

if (statp)

*statp = rxstat;

}

return (c);

}

char awaitkey2(unsigned long delay, int* error_p)

{

return (do_getc(delay, error_p));

}

#endif //HJ_add_end

在天嵌的uboot里serial.c里多出了这两个函数，待查

 

我在u-boot-1.1.6_3的cpu/arm920t/speed.c中把函数应该返回的值都用自己认为的值代替，结果可以了。我查了一些，好像MPLLCON在speed.c中没有赋值，是在boot_init中有赋值。具体的自己查查。

 

 

这里可以支持nand flash.

 

1.修改include/configs/Prodigal.h文件

增加NAND 命令：CFG_CMD_NAND | \

#define CFG_ENV_IS_IN_NAND                1

#define CFG_ENV_OFFSET 0x40000

#define CFG_ENV_SIZE                        0x20000        

#define CFG_NAND_BASE                        0

#define CFG_MAX_NAND_DEVICE                1

#define NAND_MAX_CHIPS                        1

2.添加nand_flash.c文件到cpu/arm920t/s3c24x0/目录

（建议直接拷贝TQ做好的nand_flash.c文件）

同时修改该目录下的 Makefile：

COBJS = i2c.o interrupts.o serial.o speed.o usb_ohci.o nand_flash.o

3.修改include/s3c24x0.h文件，增加S3C2440_NAND结构体

（在nand_flash.c文件中有用到）

typedef struct {

S3C24X0_REG32 NFCONF;

S3C24X0_REG32 NFCONT;

S3C24X0_REG32 NFCMD;

S3C24X0_REG32 NFADDR;

S3C24X0_REG32 NFDATA;

S3C24X0_REG32 NFMECCD0;

S3C24X0_REG32 NFMECCD1;

S3C24X0_REG32 NFSECCD;

S3C24X0_REG32 NFSTAT;

S3C24X0_REG32 NFESTAT0;

S3C24X0_REG32 NFESTAT1;

S3C24X0_REG32 NFMECC0;

S3C24X0_REG32 NFMECC1;

S3C24X0_REG32 NFSECC;

S3C24X0_REG32 NFSBLK;

S3C24X0_REG32 NFEBLK;

} S3C2440_NAND;

4、同时在 include/s3c2410.h 中添加（在nand_flash.c文件中有用到）

static inline S3C2440_NAND * const S3C2440_GetBase_NAND(void)

{

return (S3C2440_NAND * const)S3C2410_NAND_BASE;

}

 

把配置文件configs/YSJ2440.h的分区改为天嵌的uboot 暂时不改

之前添加了天嵌的boot_zImage.c文件，我在command/main.c

400行中调用了do_boot_zImage() 里面的参数都被我删除了

，本想用这个来启动内核，现在改回原型，包括Makefile

 

 

参考网站http http://blog.csdn.net/ce123/article/details/7336810 把cmd_bootm.c中的第175行开始删除linux的头部校验；

在lib_arm/armlinux.c中修改内核启动地址，在第93列改为theKernel = (void (*)(int,int,uint))addr;

可以正常启动linux了，
