    S25FL128S SPI No Response


      I am working on S25FS128S SPI. I don't get SPI response back from the Flash device. I use Single Bit Data mode.  CS, CLK, MTSR signals are good. I send RDID (0x9F/0x00/0x00/0x00). I don't receive 3 bytes of device id. MRST pin has no signal. It is my first time to work on the device. I am not sure if the device is in good condition or not. How can I verify that the device is in good condition? Are there some ways to identify whether the problem is from HW or SW?
