Ticket Name: Linux/TDA2: tda2 QSPI interface Query Text: Part Number: TDA2 Tool/software: Linux Can the tda2 QSPI interface support SDR or DDR mode communication? Responses: Hi, QSPI is used to interface with QSPI flash. EMIF is used to interface with DDR. Regards, Rishabh 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. Regards, Rishabh 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). Regards, Rishabh I have already learned through other channels,TDA does not support SPI DDR mode。 thank you。 Hi, Can you please elaborate on the solution and “other channels “. Thanks. Regards, Rishabh
