    S25FS128S interfacing problem with RTD2660

    BhuraMalik

      Hi, How can i use s25fs128s as a simple SPI flash. I am using this flash mem with RTD2660 but when i send the command 0x46(comman instruction type is read ) and 0x9f(command for Jedec ID ) but it's not responding, when i read the Jedec id  always showing 0xFFFFFF.

       

      #wp not connected  - 3

      #reset not connected -7
