教程0，下載uboot源碼：
這裏從http://www.tonylianlong.com下載，TLL提供技術和空間支持

wget http://www.tonylianlong.com/file/2013-6-21/u-boot-sunxi.zip

unzip u-boot-sunxi

cd u-boot-sunxi

教程1，添加驅動（以NAND爲例）：
A 一個一個添加：

nano include/config_cmd_default.h

而後在裏面（#endif前）添加：

#define CONFIG_CMD_NAND

提示：適合cb的網絡驅動官方沒有，我看見論壇裏好像有個教程帖子能夠弄

B 直接把全部驅動和命令都弄上：
在源碼包裏:

cd include

cp config_cmd_all.h config_cmd_default.h

cp config_cmd_all.h config_cmd_defaults.h

cd ..

而後編譯試試～
提示：若是不想要所有驅動，能夠編輯 include/config_cmd_default.h

教程2 編譯：

make cubieboard CROSS_COMPILE=arm-linux-gnueabi-

dd if=spl/sunxi-spl.bin of=/dev/sdb bs=1024 seek=8

dd if=u-boot.bin of=/dev/sdb bs=1024 seek=32

/dev/sdb是你的卡的號

教程3 DIY：
亮點1和2：
修改 include/configs/sunxi-common.h文件裏面的

#define CONFIG_IDENT_STRING " Allwinner Technology"

我改爲

#define CONFIG_IDENT_STRING " TonyLianLong Software\nQQ:1040424979"

能夠用搜索功能，nano裏的CTRL+W
提示\n是換行
亮點3，4：
修改board/sunxi/board.c

int checkboard(void)

{

printf("Board: %s\n", CONFIG_SYS_BOARD_NAME);

return 0;

}

爲

int checkboard(void)

{

//printf("Board: %s\n", CONFIG_SYS_BOARD_NAME);

printf("Board: TLL board\n"); //改你要的

return 0;

}

修改

void spl_display_print(void)

{

printf("Board: %s\n", CONFIG_SYS_BOARD_NAME);

爲

void spl_display_print(void)

{

//printf("Board: %s\n", CONFIG_SYS_BOARD_NAME);

printf("Board: TLL board\n");

}

把要刪掉的東西打上註釋是個好習慣

而後改arch/arm/cpu/armv7/sunxi/cpu_info.c
把print_cpuinfo函數改爲這樣：

int print_cpuinfo(void)

{

#ifdef CONFIG_SUN4I

puts("CPU: TLL A10 CPU\n"); //改這有用，若是用cubieboard的配置編譯

#elif defined CONFIG_SUN5I

/* TODO: Distinguish A13/A10s */

puts("CPU: Allwinner A13/A10s (SUN5I)\n"); //改這是A13和A10S的

#else

#warning Please update cpu_info.c with correct CPU information

puts("CPU: TLL other SUNXI CPU\n"); //改這是其餘sunxi處理器顯示的

#endif

return 0;

}

【第二彈】
修改common/main.c

#ifdef CONFIG_MENUPROMPT

printf(CONFIG_MENUPROMPT);

#else

if (bootdelay >= 0)

printf("Hit any key to stop autoboot: %2d ", bootdelay);

#endif

到：

#ifdef CONFIG_MENUPROMPT

printf(CONFIG_MENUPROMPT);

#else

if (bootdelay > 0){

printf("Hit any key to enter command: %2d ", bootdelay);

}else{

printf("No boot delay,start booting");

}

#endif

修改common/cmd_bootmenu.c把裏面的這個if改爲這樣：

if (menu->delay > 0) {

printf(ANSI_CURSOR_POSITION, menu->count + 5, 1);

printf(" Hit any key to enter command: %2d ", menu->delay);

}else{

printf(" No boot delay,start booting");

}

修改include/configs/sun4i.h：

#define CONFIG_SYS_PROMPT "sun4i#"

到：

#define CONFIG_SYS_PROMPT "cubie-u-boot#"

修改common/console.c：

puts("Print-In: ");

if (stdio_devices[stdin] == NULL) {

puts("No input devices available!\n");

} else {

printf ("%s\n", stdio_devices[stdin]->name);

}

puts("Print-Out: ");

if (stdio_devices[stdout] == NULL) {

puts("No output devices available!\n");

} else {

printf ("%s\n", stdio_devices[stdout]->name);

}

puts("Print-Err: ");

if (stdio_devices[stderr] == NULL) {

puts("No error devices available!\n");

} else {

printf ("%s\n", stdio_devices[stderr]->name);

}

保存編譯～（教程2）好了，就如本文開頭（第二彈還更精彩）
