baidu一下,发现有人(原文)遇到同样的错误,OK,按照原文的做,在mach-mini2440.c加入头文件,在 static void __init mini2440_map_io(void)加入红色内容

#include <linux/mtd/mtd.h>

#include

#include

#include

#include

static void __init mini2440_map_io(void)

{

    s3c24xx_init_io(mini2440_iodesc, ARRAY_SIZE(mini2440_iodesc));

    s3c24xx_init_clocks(120000000);

    s3c24xx_init_uarts(mini2440_uartcfgs, ARRAY_SIZE(mini2440_uartcfgs));

    s3c_device_nand.dev.platform_data = &mini2440_nand_info;

}

再次make试试看....

还是出现错误,提示找不到mini2440_nand_info'

arch/arm/mach-s3c2440/mach-mini2440.c: In function 'mini2440_map_io':

arch/arm/mach-s3c2440/mach-mini2440.c:172: error: 'mini2440_nand_info' undeclared (first use in this function)

arch/arm/mach-s3c2440/mach-mini2440.c:172: error: (Each undeclared identifier is reported only once

arch/arm/mach-s3c2440/mach-mini2440.c:172: error: for each function it appears in.)

make[1]: *** [arch/arm/mach-s3c2440/mach-mini2440.o] 错误 1

make: *** [arch/arm/mach-s3c2440] 错误 2

可能是分区信息在文件的后面导致找不到的原因,把第二步加入的分区信息移到最前面试试看…经过十多分钟,make成功了,把zImage下载到板上试试看

郁闷,跟第一步信息一下,到booting the kernel.就不到了. 下班了,先吃饭去,下午再回来试试.
