Error: unrecognized/unsupported machine ID

Error: unrecognized/unsupported machine ID (r1 = 0x33f60264).

解决方法一
========================================================
    Linux内核启动时出现：bad machine ID，原因大致是u-boot传递给内核的machine ID错误，可以手动在内核源代码中添加machine ID.

解决方法：
在u-boot命令行中输入bdinfo
查看板卡信息，我的输出如下:
[ ~ljh@GDLC ]# bdinfo
arch_number = 0x000000C1
env_t       = 0x00000000
boot_params = 0x30000100
DRAM bank   = 0x00000000
-> start    = 0x30000000
-> size     = 0x04000000
ethaddr     = 08:00:3E:26:0A:5B
ip_addr     = 10.1.8.245
baudrate    = 115200 bps


修改内核的arch/arm/kernel/head.S，直接将s3c2410的参数赋给内核
# cd linux-2.6.19
# vi arch/arm/kernel/head.S +72
----------------------------------------------    
70     __INIT
71     .type       stext, %function
72 ENTRY(stext)
   /********* add here *********/
   mov    r0, #0
   mov    r1, #0xc1
   ldr    r2, =0x30000100
   /********* end add *********/
73     msr cpsr_c, #PSR_F_BIT | PSR_I_BIT | SVC_MODE @ ensure svc mode
74     @ and irqs disable



解决方法二
========================================================
修改u-boot，填写ID；


# vi common/cmd_boot.c
----------------------------------------------
