AM2434: AM243 OSPI PHY Tuning parameters for Octal ISSI flash

Part Number: AM2434

Hi Team,

We would require to run Octal DDR mode with 100MHz. The OSPI controller PHY tuning is performed by referring to the link .

Could you please share the tuning parameters required for the ISSI flash - IS25WX256?

Thanks,

Akshay

  • Hi Akshay,

    the tuning parameters required for an application will depend on the board and current conditions on the moment you run the tuning algorithm. the above link points to an example condition where MX flash is used. Even if I provide you with the values that I would get from testing a platform with ISSI flash, they would correspond to that specific set up and not necessarily work for your application. 

    Do you currently have a board with the ISSI flash you are inquiring about? if you do, it is possible to obtain the required parameters for you by following instructions in the link above or even just stepping through the flash io example that contains a tuning loop where rx, tx, and rd values are obtained and set for that moment.

    Best,

    Daniel
