问： SPI_Init()没有被加载。

驱动的SPI_Init()没有被加载，注册表builtin和Active里均有spi，但是就是加载不上，SPI_Init()没有被调用。

在TQ6410.bat中将set BSP_NOSPI=1
改为set BSP_NOSPI=就会加载了

亲 set BSP_NOSPI= 设置好了，现在注册表里有spi，但是SPI_Init()还是没有调用，CreateFile(TEXT("SPI1:"),...)可以打开的，但就是不能初始化，急呀。

你凭什么依据来判断他没调用，有没有加有效的打印信息？

你调试串口开启了没有，其他驱动的调试信息看到了吗？是不是编译成3串口的那种了
