STM32F429调试记录（一）

STM32F429的芯片有两路can接口、四路串口、内部以太网以及内部dsp处理器等硬件，硬件的丰富程度可见一斑，而且主频达到180MHZ，虽然比A8-A9架构的ARM芯片还是差一大截，但是在工业控制上的应用还是比较多的。

在程序编写方面STM32F4系列不管在MDK还是库函数都有挺大改动，刚着手调试，将过程记录下来，方便以后积累经验，也让同行碰到类似问题的时候，能尽快找到方法。

首先我是用keil 来开发STM32F4系列代码的，该芯片比较新，采用keil MDK 5.11含有STM32F429芯片（4.72应该也有，但是我没验证过）；

第二、MDK会自动检测山寨版本J-link固件，上次在客户那也出现这种情况，郁闷坏了。。其实这个问题比较简单，只要把以前可以用的keil下ARM/Segger/下的JL2CM3.dll，JLinkARM.dll，放到5.11下同样目录下即可。

第三、断言报错，assert_param 模块没有定义，在options里面的c/c++中加入USE_STDPERIPH_DRIVER，即可。
