我使用mini2440开发板和其自带的Linux内核代码编译出uImage烧写到Nand flash 0x60000开始的地址空间,然后
[u-boot@MINI2440]# nand read.jffs2 0x30007fc0 0x60000 0x200000 NAND read: device 0 offset 0x60000, size 0x200000 2097152 bytes read: OK [u-boot@MINI2440]# bootm 0x30007fc0 ## Booting kernel from Legacy Image at 30007fc0 ...

我仅修改了flash分区部分的代码如下:
static struct mtd_partition friendly_arm_default_nand_part[] = { [0] = { .name = "u-boot", .size = 0x00040000, .offset = 0, }, [1] = { .name = "u-boot-env", .size = 0x00020000, .offset = 0x00040000, }, [2] = { .name = "kernel", .offset = 0x00060000, .size = 0x00500000, }, [3] = { .name = "root", .offset = 0x00560000, .size = 0x03aa0000, } }; 有u-boot使用经验的朋友帮帮忙 QQ372017601 |

$gedit arch/arm/mach-s3c2440/mach-mini2440.c
MACHINE_START(PNX4008, "FriendlyARM Mini2440 development board") 改为 MACHINE_START(MINI2440, "FriendlyARM Mini2440 development board") 在include/asm/mach-types.h中有定义 #define MACH_TYPE_PNX4008 782 #define MACH_TYPE_MINI2440 1999 |
