本人是参考友善官方<>从第一章节开始仔细阅读和试验的,现对本书中出现的漏洞和错误之处以作笔记总结,方便自已的同时希望能对他人有所帮助~
 
hardware: mini2440(64M FLASH)
platform: fedora9 under vmware
 
未标出章节为没有错误的章节,特此说明.
附标记后的友善官方<>PDF
 
3.7章节
 
参照此手册完成本章节后,编译内核之前还应再修改两处,不然不出现很多错误,在此不列出错误内容.
 
1.因为这个mach-mini2440.c是从mach-smdk2440.c处复制过来的,mach-smdk2440.c中未对nand作处理,但这里我们作处理啦,所以应在文件中加入相应的头文件
#include
#include
#include
#include
#include
2.不作下面的修改之前如果编译,以然会出现一个警告
warning:"mini2440_nand_info"defined but not used.
 
解决方法:
   在static void __init mini2440_map_io(void)
    {
    }
    中加入以下代码:
    s3c_device_nand.dev.platform_data = &mini2440_nand_info;
 
3.8章节
 
     完全按照此章节修改好程序后,编译下载到开发板,并下载自已制作适合自已开发板(64M)的文件系统,后出现下面的问题

查找资料发现有这样的说明:
  这个问题是由于arch/arm/mach-s3c2440/mach-mini2440.c中nand flash controller相关配置数据被声明为__initdata属性造成的。这部分数据会在根文件系统挂载后被释放,但事实上它们还会被nand flash driver用到,因此就出现了memory access问题。解决的办法是把arch/arm/mach-s3c2440/mach-mini2440.c中下列几行中的__initdata声明去掉:

static struct mtd_partition mini2440_default_nand_part[] __initdata = {}
static struct s3c2410_nand_set mini2440_nand_sets[] __initdata = {}

按此方法修改后,成功!

3.9章节
 
此章节基本没有什么错误,有两小处要说明:
  1)3.9.1节,DM9000网卡设备的物理基地址宏定义处
#define MACH_MINI2440_DM9K_BASE 空格 (S3C2410_CS4 + 0x300)
  2)就是在mini2440设备集中添加做好的网卡平台设备时,所说的"如下红色部分"未见红色部分,其实为
&mini2440_device_eth;

mini2440_backlight.c中只发现一小处错误,如图中黄色标记行
         
此处就改为:
           ret = copy_form_user(&ch,buffer,sizeof(ch))?-EFAULT:0;
 
另还有一处错误
即本章节结尾处说下载编译后的内核到开发板,启动时可以看到如图所示的企鹅图像,这里所说的图并未指出,其实就是第3.13章节开始的那个小企鹅图,再者经实验验证,启动内核时并不能看到这个图像,这是因为LCD驱动的程序还并没有加载进去,只能开到背光灯点亮.
          
 
3.13 linux logo
   使用netbpm工具将普通的图片转换成logo图片的时候,运行到
#pnmquant 224 linux_logo.png > linux_logo_clut224.pnm
出现问题,如下:
pnmcolormap: Error reading magic number from Netpbm image stream.  Most often, this means your input file is empty.
pnmcolormap failed, rc=256
未解决.
  另外在使用logomaker软件的时候也未说明制作图片的大小,实验发现并不是宽度和高度是任意值的图片都可以用,太大的话,制作后下载到开发板将看不到图片,个人认为应该是控制在240*240范围内.
 
3.14章节
 
此章节在应用程序的编写中有一处小错误,如图中黄色标记行
          
此处应改为:
           int len = read(fd,buffer,sizeof(buffer-1));
 
另外:实验发现在按下触摸屏时并未输出'-1'.
查找ADC驱动源代码发现:
      在没有"A/D转换器"资源时,赋值为'-1'.感觉并不是触摸一下屏时输出'-1'.
 
3.15章节
 
本章节未实验成功,编译也能通过,但就是下载到开发板上,触摸屏无反应.有待解决~
 
后来解决添加笔记:
    他细查看发现在修改相应的Makefile时将
  obj-$(CONFIG_TOUCHSCREEN_S3C2410)   += s3c2410_ts.c
写成了:
  ojb-$(CONFIG_TOUCHSCREEN_S3C2410)   += s3c2410_ts.c
造成触摸屏模块未能被编译进内核,更谈不上触摸屏无反应一说了,粗心造成的~~~~
3.16章节
 
3.16.1--3.16.2
本章节未发现问题,USB键盘,USB鼠标,USB条行码扫描器(正好公司有这个东东,就顺手测试了一下)均测试正常.
 
3.16.3--3.16.4
U盘的配置中,手册中存在未说明清楚的地方,比如在配置SCSI的时候,手册上只说如图配置,然后将<*>SCSI disk support 配置项标记了,其实不然,在配置这个选择之前应该先配置<*>SCSI device support,否则,下面的配置将不会出现*选项,只有M和空选项,这也将影响到USB Mass Storage support选项的配置.
 
          
另外有一点需要读者注意的,手册本省没有错(因为我在这里就犯了错,所以才贴出来~),就是测试U盘的时候,插入U盘后,内核会自动在根目录下创建udisk(可不是/mnt目录下呀~我就晕在这里啦~)目录,U盘将挂载在此.
 
3.16.4--3.16.5
USB摄像头的配置出现说明不清,应按下图所示进行操作
          
编译下载到开发板后,找来公司的USB摄像头,测试通过.
 
3.16.7--3.16.8
由于本手册3.16.8未编写,本人手里没有USB无线网卡,估计本功能未进行验证.
 
3.16.9--3.16.10
USB转串口功能章节友善未编写,故未验证.
 
3.17章节

启动系统后,插入SD卡无反应,解决方法:
在mach-mini2440.c文件中的
static void __init mini2440_machine_init(void)
{
}
中,应再加入一句:
s3c_device_sdi.dev.platform_data = &mini2440_mmc_cfg;
 
重新编译,下载到开发板后,上面红色标记行将会变成:
s3c-sdi s3c2440-sdi: powered down.
s3c-sdi s3c2440-sdi: mmc0 - using pio, sw SDIO IRQ
 
另外实验发现SD卡并不能被自动挂载到开发板的/sdcard目录,任务栏中也没有多出你手册上说的那样一个图标.所以只能手动挂载.
[root@FriendlyARM /]# cat /proc/partitions  //查看分区信息
major minor  #blocks  name

[root@FriendlyARM /]# mount /dev/mmcblk0 /mnt/cdrom  //手动挂载SD卡到相应目录
 
3.19章节
 
   由于手里没有和开发板相应大小的CON3接口,故本章节放到以前再验证.
