    I am using the ev-21569-som development board and running the example routine ospi_flashdirectaccess. I've noticed that the program's read and write operations are not correct. Could you please help me identify the possible issues? Are there any other examples you could provide?

      Hi,
       
      Thank you for your inquiry.
       
      We observed the same issue (incorrect read and write operations) while running the "ospi_flashdirectaccess" example. Despite this, we tested the same example from the EV-2156x_EZ-KIT-Rel1.0.1 BSP, and it worked correctly. We are planning to check this with our Internal Development team.
      

      But the same application works fine in EV-2156x_EZ-KIT-Rel1.0.1 BSP.
      

      Please download and install this BSP package "EV-2156x_EZ-KIT-Rel1.0.1" from the link below:
       
      download.analog.com/.../ADI_EV-2156x_EZ-KIT-Rel1.0.1.exe
       
      After successful installation, you can find the example in the following path:
       
      <installation>\Analog Devices\EV-2156x_EZ-KIT-Rel1.0.1\EV-2156x_EZ-KIT\Examples\drivers\ospi\ospi_flashdirectaccess
       
      Can you please run this example and let us know how you are getting on.
      

      Best Regards,
      Santhakumari.V
