你好,

非常感谢你的回答。但是我其实是想问如何像k60、stm32那样,使用内部flash储存一些数据(比如某个变量的数据)?

希望再次收到你的回复。

Hi,

There is an example in SDK_2.7.0_EVK-MIMXRT1064\boards\evkmimxrt1064\driver_examples\flexspi\nor

你好,

感谢你的回答。你提及的demo是操作外部flash的,请问有没有操作内部flash的例子。

Hi,

确实是没有写flexspi2的例子。你可以参考flexspi1的例子,从它上面改。flexspi1和flexspi2的结构和程序是一样的。

Hi,

我想Jeremy的意思应该是EVK板上的flash是ISSI的,但是RT1064内嵌的是MXIC的。LUT表是要改的。如果用ROMboot的参数和函数就比较方便,省了设置的麻烦。
