Zynq 7000 Flash Compatibility

go_er00
go_er00 over 4 years ago

Dear Sir:

 

       I would like to verify the compatibility of the flash, non-volatile, memory that I plan to interface with my Zynq 7000 Avnet Zedboard.

 

       I plan to use a Micron, serial, NOR, flash - N25Q256A.

 

       UG908  asserts that the Micron, manufacturer family, "N25Q" is compatible.   Please see the screenshot below that I have uploaded for your convenience.

 

       However, the term "Device Alias" is a term that is not well specified, and references N25Q64 

 

       I would like to eliminate the uncertainty of how to interpret the data found in UG908, can anyone tell me with certainty that the N25Q256A flash is compatible with the Zynq 7000 QSPI IP interface

or that the N25Q256A is incompatibe with my Avnet Zedboard?

 

       Thank you for your time and consideration.

    Hi, again,

     

          This discussion gets a little confusing because of how "UG908" - Vivado Programming and Debug - is specifying flash compatibility.

     

          Please see the next screenshot that I have uploaded for your convenience.

     

          The designation of the flash that I plan to interface, N25Q256A, is referenced, however, it is cross-listed under a different Micron family name.

     

          Hopefully, someone can answer my question

    My apologies for troubling anyone looking into this question.    I can answer my own question.    I overlooked UG908 again (a different version of UG908) and I saw an exact reference to the N25Q256 part/family and a corresponding matching "device alias."

     

    I am posting a screenshot to be complete:
