一  在commond env_nand.c: In function ‘saveenv‘:env_nand.c:196: error: stray ‘#‘ in programenv_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 programenv_nand.c:201: error: expected ‘)‘ before ‘define‘env_nand.c:201: error: too few arguments to function ‘nand_write‘env_nand.c: In function ‘env_relocate_spec‘:env_nand.c:276: error: stray ‘#‘ in programenv_nand.c:276: error: expected ‘)‘ before ‘define‘env_nand.c:276: error: too few arguments to function ‘nand_read‘make[1]: *** [env_nand.o] 錯誤 1make[1]:正在離開目錄 `/home/cgc/yangshanjin/u-boot-1.1.6_3/commonmake: *** [common/libcommon.a] 錯誤 2因此 我就把有錯誤的語句注釋掉，即196 201 276二  上面問題搞定，我用注釋的辦法 現在 又有問題如下/gcc/arm-none-linux-gnueabi/4.3.3/armv4t/libgcc.a(_udivdi3.o) has EABI version5, but target u-boot has EABI version 0arm-linux-ld: failed to merge target specific data of

`raise‘make: *** [u-boot] 錯誤1解決辦法 我修改辦法 修改cpu/arm920t/config.mk檔案中的 PLATFORM_RELFLAGS += -fno-strict-aliasing  -fno-common-ffixed-r8 \   -msoft-float改為PLATFORM_RELFLAGS += -fno-strict-aliasing-fno-common -ffixed-r8還是一樣的錯誤我的參考網站http://bbs.chinaunix.net/forum.php?mod=viewthread&action=printable&tid=1938330解決辦法（成功）在頂層Makefile把CROSS_COMPILE=…………（你的交叉編譯器），改為：CROSS_COMPILE=/opt/EmbedSky /crosstools_3.4.5_softloat/gcc-3.4.5-glibc-2.3.6/arm-linux/bin/arm-linux-就可正常編譯成功。無列印資訊。參考網站http://www.armbbs.net/forum.php?mod=viewthread&tid=6442我的修改一在include/configs/YSJ2440.h裡修改#define CONFIG_SMDK2440 1                                  #define  CONFIG_S3C2440  1 我已經改回來了要不的話就會報錯修改二 在include/s3c2410.h 中添加了 #include <s3c2440.h>我把s3c2440.h刪除掉了，因為其作用是跟s3c24x0.h是一樣的今天發現configs/YSJ2440.h是應該許多先行編譯中變數的定義，還有s3c2410.h裡包含了s3c24x0.h 我把YSJ2440.C board_init函數中對於s3c2410的時鐘設定消去，用if(0)我把cpu/arm920t/s3c24x0/nand_flash.c有關2410的nand_flash都注釋掉出現錯誤nand_flash.c: In function `board_nand_init‘:nand_flash.c:140: error: `s3c2410_nand_hwcontrol‘ undeclared (first use in thisfunction)nand_flash.c:140: error: (Each undeclared identifier is reported only oncenand_flash.c:140: error: for each function it appears in.)nand_flash.c:141: error: `s3c2410_nand_devready‘ undeclared (first use in thisfunction)nand_flash.c:142: error: `s3c2410_nand_select_chip‘ undeclared (first use inthis function)make[1]: *** [nand_flash.o] 錯誤 1make[1]:正在離開目錄 `/home/cgc/yangshanjin/u-boot-1.1.6_3/cpu/arm920t/s3c24x0‘現在複原 我修改了cpu/arm920t/start.S中的160行 把bl cpu_init_crit注釋掉接著修改/board/YSJ2440/config.mk中TEXT_BASE 值為0x33000000還是搞回來修改relocate:adrr0, _startldrr1, _TEXT_BASEcmp     r0, r1      beq     clear_bss@ldr r2, _armboot_startldr   r1,_armboot_startldrr3, _bss_startsubr2, r3, r2#if 1bl CopyCode2Ram#elseaddr2, r0, r2copy_loop:ldmiar0!, {r3-r10}stmiar1!, {r3-r10}cmpr0, r2ble copy_loop#endif#endif  我把上面的ldr r1, r1,_armboot_start     修改為mov r1,#0x33f80000  但是報錯 start.S:181: Error: invalid constant -- `mov r1,#0x33f80000‘ 原來是精簡指令問題我改成ldr r1,=0x33f80000,就可以了 ，但是還是啟動不了核心， start.S 設定完中斷向量表後 ， 加上這句是什麼意思.balignl 16,0xdeadbeef  #if 1 //HJ_add_startint 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裡serial.c裡多出了這兩個函數，待查 我在u-boot-1.1.6_3的cpu/arm920t/speed.c中把函數應該返回的值都用自己認為的值代替，結果可以了。我查了一些，好像MPLLCON在speed.c中沒有賦值，是在boot_init中有賦值。具體的自己查查。  這裡可以支援nand flash. 1.修改include/configs/Prodigal.h檔案增加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                        12.添加nand_flash.c檔案到cpu/arm920t/s3c24x0/目錄（建議直接拷貝TQ做好的nand_flash.c檔案）同時修改該目錄下的 Makefile：COBJS = i2c.o interrupts.o serial.o speed.o usb_ohci.o nand_flash.o3.修改include/s3c24x0.h檔案，增加S3C2440_NAND結構體（在nand_flash.c檔案中有用到）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、同時在 include/s3c2410.h 中添加（在nand_flash.c檔案中有用到）static inline S3C2440_NAND * const S3C2440_GetBase_NAND(void){return (S3C2440_NAND * const)S3C2410_NAND_BASE;} 把設定檔configs/YSJ2440.h的分區改為天嵌的uboot 暫時不改之前添加了天嵌的boot_zImage.c檔案，我在command/main.c400行中調用了do_boot_zImage() 裡面的參數都被我刪除了，本想用這個來啟動核心，現在改回原型，包括Makefile  參考網站http http://blog.csdn.net/ce123/article/details/7336810 把cmd_bootm.c中的第175行開始刪除linux的頭部校正； printf ("## Booting image at lx ...\n", addr)； #ifdef CONFIG_HAS_DATAFLASHif
