u-boot的2010.03版本最接近三星定制的s3c-u-boot-1.1.6版本，所以选此版本尝试移植。对于arm11架构的芯片，u-boot-2010.03仅支持6400，我们可以复制并修改6400的相关文件，使u-boot支持6410。

1.获得源码

到http://ftp.denx.de/pub/u-boot/下载u-boot-2010.03.tar.bz2，解压。

2.首次编译

在u-boot根目录配置并编译

 

make smdk6400_config 
make

 

编译成功，在u-boot根目录下生成的u-boot.bin即为u-boot镜像。

3.文件添加

 

make clean

 

3.1）board目录

 

cd board/samsung/
mkdir smdk6410
cp smdk6400/* smdk6410/
cd smdk6410
mv smdk6400.c smdk6410.c

 

将目录下所有文件中的。

查找board/samsung/smdk6410目录下含有“6400”的文件，将这些文件中的“6400”替换成“6410”。vim下的替换命令是“:%s/6400/6410/g”。

 

[root@tanghuimin smdk6410]# find . -name "*" | xargs grep "6400"
./Makefile:COBJS-y    := smdk6400.o
./lowlevel_init.S:#include <asm/arch/s3c6400.h>

./smdk6410.c:ulong virt_to_phy_smdk6400(ulong addr)
[root@tanghuimin smdk6410]# 

 

3.2)cpu目录

查找cpu/arm1176目录下含有“6400”的文件，将这些文件中的“6400”替换成“6410”。vim下的替换命令是“:%s/6400/6410/g”。

 

[root@tanghuimin arm1176]# pwd
/home/thm/u-boot/u-boot-2010.03/cpu/arm1176

3.3)nand_spl目录

 

cd nand_spl/board/samsung/
mkdir smdk6410
cp smdk6400/* smdk6410/
cd smdk6410

 

查找nand_spl/board/samsung/smdk6410目录下含有“6400”的文件，将这些文件中的“6400”替换成“6410”。vim下的替换命令是“:%s/6400/6410/g”。

 

[root@tanghuimin smdk6410]# pwd
/home/thm/u-boot/u-boot-2010.03/nand_spl/board/samsung/smdk6410
[root@tanghuimin smdk6410]# 
[root@tanghuimin smdk6410]# find . -name "*"| xargs grep "6400"
./Makefile:    @ln -s $(TOPDIR)/board/samsung/smdk6400/lowlevel_init.S $@
./lowlevel_init.S:#include <asm/arch/s3c6400.h>
./lowlevel_init.S:    /* r1 = physical address of s3c6400_cpu_resume function */
./lowlevel_init.S:    /* Jump to kernel (sleep-s3c6400.S) */
./lowlevel_init.S:     * seem to make much sense on S3C6400.
./lowlevel_init.S:#ifndef CONFIG_S3C6400
./lowlevel_init.S:#elif !defined(CONFIG_S3C6400)

./config.mk:# Samsung S3C64xx Reference Platform (smdk6400) board
[root@tanghuimin smdk6410]# 

 

3.4）添加头文件smdk6410.h

cd include/configs
cp smdk6400.h smdk6410.h
vim smdk6410.h
:%s/6400/6410/g

3.5）添加头文件s3c6410.h

cd include/asm-arm/arch-s3c64xx/
cp s3c6400.h s3c6410.h
vim s3c6410.h
:%s/6400/6410/g

并且修改

 

#include "s3c64x0.h"

 

为

#include "./asm/arch/s3c64x0.h"

3.6）修改根目录下mkconfig

if [ "$2" = "arm" ] ; then
    rm -f asm-$2/proc
    ln -s ${LNPREFIX}proc-armv asm-$2/proc
fi

if [ "$1" = "smdk6410" ]; then
    rm -f regs.h
    ln -s asm-$2/arch/s3c6410.h regs.h
fi

3.7）修改根目录下Makefile

搜索6400可以看到smdk6400的配置项，复制smdk6400的配置项并把6400改为6410。

3.8)配置编译

 

make smdk6410_config
make

 

可以编译成功。

4.文件修改

4.1)cpu/arm1176/start.S

4.1.1）将如下红色代码段注释掉，添加“mcr p15,0,r0,c1,c0,0”。

 

#ifndef CONFIG_NAND_SPL 
        /* 
         * flush v4 I/D caches 
         */ 
        mov     r0, #0 
        mcr     p15, 0, r0, c7, c7, 0   /* flush v3/v4 cache */ 
        mcr     p15, 0, r0, c8, c7, 0   /* flush v4 TLB */ 

        /* 
         * disable MMU stuff and caches 
         */ 
        mrc     p15, 0, r0, c1, c0, 0 
        bic     r0, r0, #0x00002300     @ clear bits 13, 9:8 (--V- --RS) 
        bic     r0, r0, #0x00000087     @ clear bits 7, 2:0 (B--- -CAM) 
        orr     r0, r0, #0x00000002     @ set bit 2 (A) Align 
        orr     r0, r0, #0x00001000     @ set bit 12 (I) I-Cache 

        /* Prepare to disable the MMU */ 
        adr     r1, mmu_disable_phys 

        /* We presume we're within the first 1024 bytes */ 
        and     r1, r1, #0x3fc 
        ldr     r2, _TEXT_PHY_BASE 
        ldr     r3, =0xfff00000 
        and     r2, r2, r3 
        orr     r2, r2, r1 
        b       mmu_disable 

        .align 5 

        /* Run in a single cache-line */ 

mmu_disable: 
        mcr     p15, 0, r0, c1, c0, 0 nop nop mov pc, r2 

#endif 

 

修改后的代码如下：

 

#ifndef CONFIG_NAND_SPL 
        /* 
         * flush v4 I/D caches 
         */ 
        mov     r0, #0 
        mcr     p15, 0, r0, c7, c7, 0   /* flush v3/v4 cache */ 
        mcr     p15, 0, r0, c8, c7, 0   /* flush v4 TLB */ 

        /* 
         * disable MMU stuff and caches 
         */ 
        mrc     p15, 0, r0, c1, c0, 0 
        bic     r0, r0, #0x00002300     @ clear bits 13, 9:8 (--V- --RS) 
        bic     r0, r0, #0x00000087     @ clear bits 7, 2:0 (B--- -CAM) 
        orr     r0, r0, #0x00000002     @ set bit 2 (A) Align 
        orr     r0, r0, #0x00001000     @ set bit 12 (I) I-Cache 

      mcr p15, 0, r0, c1, c0, 0 
#if 0 
        /* Prepare to disable the MMU */ 
        adr     r1, mmu_disable_phys 

        /* We presume we're within the first 1024 bytes */ 
        and     r1, r1, #0x3fc 
        ldr     r2, _TEXT_PHY_BASE 
        ldr     r3, =0xfff00000 
        and     r2, r2, r3 
        orr     r2, r2, r1 
        b       mmu_disable 

        .align 5 

        /* Run in a single cache-line */ 

mmu_disable: 
        mcr     p15, 0, r0, c1, c0, 0 
        nop 
        nop 
        mov     pc, r2 
#endif 

#endif 

 

4.1.2）查找“lowlevel_init”，在其下添加

 

 /* when we already run in ram, we don't need to relocate U-Boot. 
         * and actually, memory controller must be configured before U-Boot 
         * is running in ram. 
         */ 
        ldr     r0, =0xff000fff 
        bic     r1, pc, r0              /* r0 <- current base addr of code */ 
        ldr     r2, _TEXT_PHY_BASE      /* r1 <- original base addr in ram */ 
        bic     r2, r2, r0              /* r0 <- current base addr of code */ 
        cmp     r1, r2                  /* compare r0, r1                  */ 
        beq     after_copy 

#ifdef CONFIG_BOOT_NAND 
        mov     r0, #0x1000 
        bl      copy_from_nand 
#endif

 

4.1.3）查找

 

#ifdef CONFIG_ENABLE_MMU 
_mmu_table_base: 
        .word mmu_table 
#endif

 

在其下添加

 

/* 
 * copy U-Boot to SDRAM and jump to ram (from NAND or OneNAND) 
 * r0: size to be compared 
 * Load 1'st 2blocks to RAM because U-boot's size is larger than 1block(128k) size 
 */ 
        .globl copy_from_nand 
copy_from_nand: 
        mov     r10, lr         /* save return address */ 

        mov     r9, r0

        bne     compare_failed  /* not matched */ 
        subs    r9, r9, #4 
        bne     1b

        b       copy_failed 

compare_failed: 
        nop                     /* compare failed */ 
        b       compare_failed

 

4.2）在cpu/arm1176下添加nand_cp.c

4.6）修改nand_spl/board/samsung/smdk6410/Makefile

COBJS   = nand_boot.o nand_ecc.o s3c64xx.o nand_cp.o

补全规则

 

# from SoC directory 
$(obj)cpu_init.S: 
        @rm -f $@ 
        @ln -s $(TOPDIR)/cpu/arm1176/s3c64xx/cpu_init.S $@ 

$(obj)nand_cp.c: 
        @rm -f $@ 
        @ln -s $(TOPDIR)/cpu/arm1176/nand_cp.c $@ 

 

4.7）修改根目录下u-boot.lds

 .text : 
 { 
   cpu/arm1176/start.o (.text) 
   cpu/arm1176/s3c64xx/cpu_init.o (.text) 
   board/samsung/smdk6410/lowlevel_init.o (.text) 
   cpu/arm1176/nand_cp.o (.text) 
   lib_arm/board.o (.text) 
   *(.text) 
 } 

4.8）修改include/configs/smdk6410.h

#if !defined(CONFIG_NAND_SPL) && (TEXT_BASE >= 0xc0000000)
#define CONFIG_ENABLE_MMU
#ifdef CONFIG_ENABLE_MMU
#define virt_to_phys(x) virt_to_phy_smdk6410(x)
#else
#define virt_to_phys(x) (x)
#endif
#endif

#define MACH_TYPE               2520

//#define PHYS_SDRAM_1_SIZE     0x08000000      /* 128 MB in Bank #1    */ 
#define PHYS_SDRAM_1_SIZE       0x10000000      /* 256 MB in Bank #1    */

//#define CONFIG_SYS_HZ                 1000 
#define CONFIG_SYS_HZ                   2062500 //PCLK 66HZ

文件末尾添加

 

#define NAND_DISABLE_CE()       (NFCONT_REG |= (1 << 1)) 
#define NAND_ENABLE_CE()        (NFCONT_REG &= ~(1 << 1)) 
#define NF_TRANSRnB()           do { while(!(NFSTAT_REG & (1 << 0))); } while(0)

#define CFG_PHY_UBOOT_BASE      CONFIG_SYS_PHY_UBOOT_BASE

 

4.9）再次编译，生成u-boot.bin，将u-boot.bin烧写到nand flash，开发板从nand flash启动。

打印信息如下：

5. 问题解决

开发板从nand flash启动时，有异常信息打印。

 

 

5.1）问题1：

 

DRAM:   0 kB

 

解决方法：

将include/asm_arm/global_data.h中

 

#define DECLARE_GLOBAL_DATA_PTR     register volatile gd_t *gd asm ("r8")

 

修改为

 

#define DECLARE_GLOBAL_DATA_PTR     extern volatile gd_t *gd;

 

将lib_arm/board.c中

 

DECLARE_GLOBAL_DATA_PTR;

 

修改为

 

volatile gd_t *gd;

 

5.2）问题2：

 

NAND:  raise: Signal # 8 caught 
raise: Signal # 8 caught 
raise: Signal # 8 caught 
NAND device: Manufacturer ID: 0xec, Chip ID: 0xd5 (Samsung NAND 2GiB 3,3V 8-bit) 
NAND bus width 8 instead 16 bit 
No NAND device found!!! 
0 MiB

 

解决方法：

将drivers/mtd/nand/s3c64xx.c函数board_nand_init中

 

nand->options           = 0;

 

改为

 

nand->options           = 0x20000;

 

将drivers/mtd/nand/nand_base.c函数nand_get_flash_type中

 

busw = (extid & 0x01) ? NAND_BUSWIDTH_16 : 0;

 

改为

busw = 0;

修改cpu/arm1176/s3c64xx/timer.c中函数get_timer_masked（解决“raise: Signal # 8 caught” ）

 

ulong get_timer_masked(void)                                                                                                                                        { 
        unsigned long long res = get_ticks(); 
        //do_div (res, (timer_load_val / (100 * CONFIG_SYS_HZ))); 

        return res;  
} 

 

5.3）问题三：

 

*** Warning - bad CRC, using default environment

 

暂时无解，此警告不影响u-boot功能。

 

 

重新编译，烧写，启动

6.修改网卡配置

smdk6400.h中网卡配置为CS8900，而开发板上的网卡为DM9000，网卡相关配置修改如下：

6.1）修改include/configs/smdk6410.h

/*
 * Hardware drivers
 */
#define CONFIG_NET_MULTI
//#define CONFIG_CS8900            /* we have a CS8900 on-board    */
//#define CONFIG_CS8900_BASE          0x18800300
//#define CONFIG_CS8900_BUS16        /* follow the Linux driver    */

#define CONFIG_DRIVER_DM9000    1    /* we have a DM9000 on-board    */
#define CONFIG_DM9000_USE_16BIT    1
#define CONFIG_DM9000_BASE    0x18000300
#define DM9000_IO    CONFIG_DM9000_BASE
#define DM9000_DATA    (CONFIG_DM9000_BASE+4)

#define CONFIG_ETHADDR    08:90:90:90:90:90
#define CONFIG_NETMASK    255.255.255.0
#define    CONFIG_IPADDR    192.168.1.230
#define CONFIG_SERVERIP    192.168.1.88
#define CONFIG_GATEWAYIP    192.168.1.1

6.2）修改net/eth.c

#if defined(CONFIG_DB64360) || defined(CONFIG_CPCI750) 
    mv6436x_eth_initialize(bis); 
#endif 
#if defined(CONFIG_DB64460) || defined(CONFIG_P3Mx) 
    mv6446x_eth_initialize(bis); 
#endif 

#if defined(CONFIG_DRIVER_DM9000) 
    dm9000_initialize(bis); 
#endif
