大家好,  我的板子是MINI6410  NAND：256M，DDR 256M  LCD ：H43

按照http://www.aiothome.net/read.php?tid-10788.html 的步骤,做了如下操作:

步骤1 增加头文件
#include <linux/spi/spidev.h>
#include <linux/spi/spi.h>
#include <plat/s3c64xx-spi.h>  
步骤2 配置内核选项
Device Drivers  ---> [*] SPI support  ---> <M>   Samsung S3C24XX series SPI
                                           <M>   User mode SPI device driver support      
步骤三:
   增加 &s3c64xx_device_spi0, 到 --->>> [static struct platform_device *mini6410_devices[]] 的末尾    
   增加 add [obj-y       +=dev-spi.o] 到 arch/arm/mach-s3c64xx/Makefile
   在头文件语句的下面增加  
     static void  cs_set_level(unsigned line_id, int lvl) {
    gpio_direction_output(line_id, lvl);
};
static struct s3c64xx_spi_csinfo s3c64xx_spi0_csinfo = {
  .fb_delay=100,
  .line=S3C64XX_GPC(3),
  .set_level=cs_set_level,
};
static struct spi_board_info s3c6410_spi0_board[] = {
[0] = {
.modalias = "spidev",
.bus_num= 0,
.chip_select= 0, //必须小于s3c6410_spi0_platdata.num_cs
.irq =IRQ_SPI0,
.max_speed_hz= 500*1000,
.mode=SPI_MODE_0,
.controller_data=&s3c64xx_spi0_csinfo,
},
};
在mini6410_machine_init(before platform_add_devices)中增加
[ s3c64xx_spi_set_info(0,0,1);   //gzj++
       //s3c64xx_spi_set_info(1,0,1);

       spi_register_board_info(s3c6410_spi0_board, ARRAY_SIZE(s3c6410_spi0_board));
     // spi_register_board_info(s3c6410_spi1_board, ARRAY_SIZE(s3c6410_spi1_board));
  ]
    
步骤四:
        do make zImage
        do make
然后再6410的板子上执行:
             insmod spi_s3c64xx.ko  
             insmod spidev.ko  
            
            
             结果打印的信息是这样的:
            
[root@FriendlyARM plg]# insmod spi_s3c64xx.ko

请教一下

这样的操作过后，可以在/dev下生成对应的spidev0.0这个设备，spi也可以首发，但是问题是： 当接收大概4－－8个包以后，就不再接收 了，就是说我应用层读不来了。

从给板子上电，到 insmod 后出现错误的打印信息，如下：

这个错误信息不会导致SPI的硬件通信问题，它只是在你没有调用gpio_request的情况下就操作相应gpio的情况下的一个警告。我想通信的问题还是需要从SPI上的读取和发出数据分析入手。

哦，谢谢了，你说的GPIO是不是 SPI的   .line=S3C64XX_GPC(3), 这个引脚，因为只有这个引脚的我调用GPIO的库来设置的。

现在的问题是：我能确定SPI的 CLK MISO MOSI是正常的，因为我把发送和接收脚短接，发现发送和接收数据完全正常的。
但我现在不能保证  .line=S3C64XX_GPC(3), 这个引脚是不是正常的，因为我在实际中发现 当外面接上spi的芯片时，小数据(比如读写某个寄存器)是正常的，但是如果大数据量 就会出现接收的数据错误， 请教下！！
谢谢了！

请问下楼主，我一直怀疑是 spi的cs脚 没有正常的拉高或拉低导致的，请问下这个SPI的cs脚只是设置了输出，他会自动的把GPC3脚设置为输出模式，并且是输出为1或0 吗，谢谢！

负责输出0或1的是下面的代码：

在头文件语句的下面增加  
     static void  cs_set_level(unsigned line_id, int lvl) {
    gpio_direction_output(line_id, lvl);
};
static struct s3c64xx_spi_csinfo s3c64xx_spi0_csinfo = {
  .fb_delay=100,
  .line=S3C64XX_GPC(3),
  .set_level=cs_set_level,
};

另外，在gpio_direction_output()里最终应该会调用到arch/arm/plat-samsung/gpio.c里的 s3c_gpiolib_output()函数，在它里面会把对应GPIO的模式设置成output

复制代码 67 static int s3c_gpiolib_output(struct gpio_chip *chip, 68                               unsigned offset, int value) 69 { 70         struct s3c_gpio_chip *ourchip = to_s3c_gpio(chip); 71         void __iomem *base = ourchip->base; 72         unsigned long flags; 73         unsigned long dat; 74         unsigned long con; 75 76         s3c_gpio_lock(ourchip, flags); 77 78         dat = __raw_readl(base + 0x04); 79         dat &= ~(1 << offset); 80         if (value) 81                 dat |= 1 << offset; 82         __raw_writel(dat, base + 0x04); 83 84         con = __raw_readl(base + 0x00); 85         con &= ~(3 << (offset * 2)); 86         con |= 1 << (offset * 2); 87 88         __raw_writel(con, base + 0x00); 89         __raw_writel(dat, base + 0x04); 90 91         s3c_gpio_unlock(ourchip, flags); 92         return 0; 93 }

感谢总版主，亲自找到源代码的位置并贴出来， 让人感动啊。！

我在积极的找这个问题的解决的办法，等找到了，贴上来，以免以后有人也遇到这样的问题，谢谢了

这没有什么。在我看来，在这里讨论问题如果脱离了源代码，是一点意义也没有的。事实上这也是论坛上很多问题得不到解决的一个重要原因。

拜读了。。。

请问楼主现在这个问题解决了吗，后来人又遇到同样问题了，求指导啊~~
