We can use IAP command to get device ID,

/* Read part identification number */
status = IAP_ReadPartID(&partID);

There is demo code under SDK iap_basic which includes the command usage.

Have a nice day,

Hi Karthikeyan

In-Application (IAP) programming is performing erase and write operation on the on-chip flash memory, It is not for external SPIFI flash.

If you want to operate external SPIFI flash, please refer demo code spifi_polling_transfer and spifi_dma_transfer in SDK folder.

Have a nice day,
