我也对照了以下这个表, 只是不知道默认该怎么配置了, 我也就接一个SPI的TFT.

8.5   [spi_devices]

将 bus_num = 2 可以生成了 现在测试 读写

嗯. 晚上回去再试试修改下这些参数. 不知道CT的有哪里可以查到这些参数定义不.

另外能加你QQ沟通吗?

如果是旧的内核，看modalias，这个名字要跟spidev.c中的相同.name =  "spidev"是否一样，还有更新了新的SPI-SUNXI
这是我的配置
[spi_board0]
modalias = "spidev"
max_speed_hz = 12000000
bus_num = 0         设为0
chip_select = 0
mode = 3
full_duplex = 0
manual_cs = 0

这个补丁文件中，有一个头文件找不到：
  1. #include <plat/sys_config.h>
复制代码

当我把这个头文件换成：
  1. #include <mach/sys_config.h>
复制代码
它编译的时候又报这个错误：

换3.4内核或添加plat/sys_config.h ，这个是解析script.bin的库非常重要

是这个吗？

另外，我把android  linux-3.3 替换成linux-3.4 会不会需要修改什么脚本文件呢..

android 3.3 和  linux-3.4 还是有区别的，肯定不能简单替换，加个库文件吧， 我也没编译过android的驱动
