    interfacing S25FL127S with STM32

              Hi, Is it possible to provide any sample code for interfacing S25FL127S with any of the STM32 controller.

          Hello Sathyavathi,


          We do not have any sample code with STM32 controller. We do have sample code with our PSoC which can be used as reference.


          I am attaching the project where basic code for read and write for S25Fl512S is implemented using Cy8CKIT -042. You can use this as reference.


          The basic read and write operations will be same. Please go through it and let us know if you need any clarifications.

            Im trying to use S25FL127S with STM32F407VETX. When i send RDID(0x9F)  command i always receive 0xFFFFFF instead of getting 0x012018 (01h,20h,18h). 


            Any clue on this is appreciated.




            Hardware SetUp:


            Pin1(CS#) ----> has 10K pullup and connected to STM32 CS Pin


            Pin2(SO) ----> connected to STM32  MISO through level shifting.


            Pin3(WP#)----> 10K pullup resistor is connected. Not Connected to STM32.


            Pin4(GND)----> made SS25FL127S GND and STM32 GND common.


            Pin5(SI) --------> connected to STM32  MOSI through level shifting.


            Pin6(CLK) --------> connected to STM32  CLK through level shifting.


            Pin7(HOLD#) ------> 10K pullup resistor is connected. Not Connected to STM32.


            Pin8(VCC) -------> 3.3V




            Thank You.
