[*]U-Boot 2013.07-rc1 (Jun 21 2013 - 20:44:00) TonyLianLong Software
[*]QQ:1040424979（这也是）

复制代码
教程0，下载uboot源码：
这里从http://www.tonylianlong.com下载，TLL提供技术和空间支持
[*]wget http://www.tonylianlong.com/file/2013-6-21/u-boot-sunxi.zip
[*]unzip u-boot-sunxi
[*]cd u-boot-sunxi
[*]
复制代码
教程1，添加驱动（以NAND为例）：
A 一个一个添加：
[*]nano include/config_cmd_default.h
复制代码
然后在里面（#endif前）添加：
[*]#define CONFIG_CMD_NAND
复制代码
即可
提供驱动表，按照上面的方式，只不过是要把CONFIG_CMD_NAND替换成你要的：

复制代码
提示：适合cb的网络驱动官方没有，我看见论坛里好像有个教程帖子可以弄
B 直接把所有驱动和命令都弄上：
在源码包里:
[*]cd include
[*]cp config_cmd_all.h config_cmd_default.h
[*]cp config_cmd_all.h config_cmd_defaults.h
[*]cd ..
复制代码
然后编译试试～
提示：如果不想要全部驱动，可以编辑 include/config_cmd_default.h
教程2 编译：
[*]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
复制代码
/dev/sdb是你的卡的号
教程3 DIY：
亮点1和2：
修改 include/configs/sunxi-common.h文件里面的
[*]#define CONFIG_IDENT_STRING " Allwinner Technology"
复制代码
我改成
[*]#define CONFIG_IDENT_STRING " TonyLianLong Software\nQQ:1040424979"
复制代码
可以用搜索功能，nano里的CTRL+W
提示\n是换行
亮点3，4：
修改board/sunxi/board.c
[*]int checkboard(void)
[*]{
[*]printf("Board: %s\n", CONFIG_SYS_BOARD_NAME);
[*] return 0;
[*]}
[*]
复制代码
为
[*]int checkboard(void)
[*]{
[*] //printf("Board: %s\n", CONFIG_SYS_BOARD_NAME);
[*] printf("Board: TLL board\n"); //改你要的
[*] return 0;
[*]}
[*]
复制代码
修改
[*]void spl_display_print(void)
[*]{
[*]printf("Board: %s\n", CONFIG_SYS_BOARD_NAME);
[*]}
复制代码
为
[*]void spl_display_print(void)
[*]{
[*] //printf("Board: %s\n", CONFIG_SYS_BOARD_NAME);
[*] printf("Board: TLL board\n");
[*]}
[*]
复制代码
把要删掉的东西打上注释是个好习惯
然后改arch/arm/cpu/armv7/sunxi/cpu_info.c
把print_cpuinfo函数改成这样：
[*]int print_cpuinfo(void)
[*]{
[*]#ifdef CONFIG_SUN4I
[*] puts("CPU: TLL A10 CPU\n"); //改这有用，如果用cubieboard的配置编译
[*]#elif defined CONFIG_SUN5I
[*] /* TODO: Distinguish A13/A10s */
[*] puts("CPU: Allwinner A13/A10s (SUN5I)\n"); //改这是A13和A10S的
[*]#else
[*]#warning Please update cpu_info.c with correct CPU information
[*] puts("CPU: TLL other SUNXI CPU\n"); //改这是其他sunxi处理器显示的
[*]#endif
[*] return 0;
[*]}
复制代码
【第二弹】
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
[*]
复制代码
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
[*]
复制代码
修改common/cmd_bootmenu.c把里面的这个if改成这样：
[*] 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");
[*] }
[*]
复制代码
修改include/configs/sun4i.h：
[*]#define CONFIG_SYS_PROMPT "sun4i#"
[*]
复制代码
到：
[*]#define CONFIG_SYS_PROMPT "cubie-u-boot#"
[*]
复制代码
修改common/console.c：
[*]puts("Print-In: ");
[*] if (stdio_devices == NULL) {
[*] puts("No input devices available!\n");
[*] } else {
[*] printf ("%s\n", stdio_devices->name);
[*] }
[*]
[*] puts("Print-Out: ");
[*] if (stdio_devices == NULL) {
[*] puts("No output devices available!\n");
[*]} else {
[*] printf ("%s\n", stdio_devices->name);
[*] }
[*]
[*] puts("Print-Err: ");
[*] if (stdio_devices == NULL) {
[*] puts("No error devices available!\n");
[*] } else {
[*] printf ("%s\n", stdio_devices->name);
[*] }
[*]
[*]

保存编译～（教程2）好了，就如本文开头（第二弹还更精彩）
