After power up the module I'am trying to read the Manufacture Device ID through 1s-1s-1s transaction (SDR) giving command for reading manufacture Device ID (RDIDN_0_0) transmitting 9F with No dummy cycles, No latency cycles after that 64 bits for reading the manufacture Device Id.

PIN CONNECTION: -

SCK---> CONNECTED  

CS---> CONNECTED 

MOSI---> CONNECTED 

MISO ---> CONNECTED 

3V3---> CONNECTED 

GND--->CONNECTED 

RST---> Connected with the GPIO PIN as it is active Low driving zero 0 sometime and then de-assert to 1  

->Observed there is no transaction on the MISO line 

-> are we missing any initialization?

->initialization sequence is wrong? 

I had referred the data sheet but still didn't not an clear idea

we are using S25HL512T for our project for QSPI implementation , can you please explain here briefly, step by step procedure for QSPI how to configure and commands for that ?

 queries related to QSPI Implementation :-

1) how to read the device Id of Flash in QSPI mode 

2)how to read the data from the flash memory

3) For configuring into QSPI Mode we need to program it but by default it is in Single SPI , can you provide the sample C script so that we can edit accordingly for our project .

Hi,

Need your help, can you forward this mail to respect AE? We will create test case also.

We are using the S25FL064LABMFM010 flash in IOT project.

We want to integrate with our Chip. Do you have any document that’s define the integration of flash

Master is driving the clock and MOSI signals but we are not seeing any response from Flash.

Thanks,
