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，
