I am working with MK12DX128xxx5 flash programming, I have no MK12DX128xxx5 flash driver in hand so I use the flash drive which works well in MK10DX128xxx5. The complier is IAR Embedded Workbench for ARM 184.108.40.20670. The C/C++ Compiler Optimizations setting is High (Size). If I set some function optimize=none then the flash write data function works well, but it cannot work correctly if I remove one or two optimize=none. I checked running status of write flash function, it can write correct 1 byte and return the error of flash read collision.
My question is:
- Why the problem is related to the optimize setting?
- The MK10DX128xxx5 flash driver can be used for MK12DX128xxx5?
Somebody can post MK12DX128xxx5 flash write code?
Thank you very much!
