我的问题是F4支持多大的NAND。回答如下：
You can use NAND flash by mounting it on the FSMC of STM32F4. There is no capacity limitation to the nand flash as the D0~D7 or D0~D15 is the bus multiplexed by data and address and command. If higher capacity NAND flash is used, more address cycles would be launched on above multiplex bus when accessed.
我理解的就是NAND大小无限制，但是寻址的方法更复杂了（多轮？），但网上的示例代码基本都是用ST官方改的，不知道自己该怎么改啊，感觉很复杂 |
