S25HL512T QSPI flash

[Shraddha]

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?

Hello,

Could you please check how much time you are waiting after Power up to Device ID read operation? As mentioned in the datasheet, you need to wait for tPU time after VCC reaches VCC(min) before reading device ID.

You can find more details about tPU parameter on page 70 of our datasheet, https://www.infineon.com/dgdl/Infineon-S25HS256T_S25HS512T_S25HS01GT_S25HL256T_S25HL512T_S25HL01GT_2....

Thanks and Regards,
