&请教下SPI驱动 加载的问题

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 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-& 72&&&&&&&& 73&&&&&&&& 74&&&&&&&& 75
76&&&&&&&& s3c_gpio_lock(ourchip, flags); 77
78&&&&&&&& dat = __raw_readl(base + 0x04); 79&&&&&&&& dat &= ~(1 && offset); 80&&&&&&&& if (value) 81&&&&&&&&&&&&&&&& dat |= 1 && 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 }

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。
