Hi,

QSPI is used to interface with QSPI flash. EMIF is used to interface with DDR.

Hi，Rishabh

You mean the TDA QSPI interface only supports SDR, right?

Because I found some SPI Flash ICs can support the following modes:
Single Data Rate (SDR)
Double Data Rate (DDR)

Hi,

If think you are referring to single and quad bit mode. QSPI supports both.

Hi,

I haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).
