Thanks for your reply. I have tried to do what as your suggestion, But there is no option about the Fatfs on LPC54606 SDK. I can find the option on LPC54608 samples. why? due to my SDK downloaded from NXP server?
Maybe it is not the root cause that the SDK package includes the Fatfs file or not. I have created two projects with the same SDK as below, and make sure that the SDK includes the Fatfs file .
So what i should do next?
thanks for your quick reply very much!
Understand what your said. If i create the project based on LPC54608, there is the fatfs option in Middleware for selecting. however there is not fatfs option in Middleware for selecting while creating project based on LPC54606.
