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 ..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/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"我改成#define CONFIG_IDENT_STRING " TonyLianLong Software\nQQ:1040424979"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.cint checkboard(void)
{
printf("Board: %s\n", CONFIG_SYS_BOARD_NAME);
return 0;
}
为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);
}为void spl_display_print(void)
{
//printf("Board: %s\n", CONFIG_SYS_BOARD_NAME);
printf("Board: TLL board\n");
}
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;
}【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
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");
}
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 == 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） 有没有U-boot的NAND驱动？？？？求一个 andy 发表于 2013-6-22 11:05 static/image/common/back.gif
有没有U-boot的NAND驱动？？？？求一个
早就有了，下次给教程 andy 发表于 2013-6-22 11:05 static/image/common/back.gif
有没有U-boot的NAND驱动？？？？求一个
教程来了 我手上的u-boot移植了网络驱动，我测试了tftp功能
把你这个nand加进去，就达到我使用的要求了 我在你给的网址下的u-boot不对呀，实测nand不能用，你移植成功了吗？
分享一下呗
