Thank you for contacting Cypress Community.
Micron MT29F is software compatible with Cypress S34ML-2.
We have an Application Note for migrating from MT29F to S34ML-1 (http://www.cypress.com/file/197966/download ), and since S34ML-2 is backward compatible with S34ML-1, you can use this AN as a reference for migrating from MT29F to S34ML-2 as well.
For further clarity, here is the link to the Application Note for migrating from S34ML-1 to S34ML-2 (https://www.cypress.com/documentation/application-notes/an200516-migration-s34ml-1-s34ml-2 ), which compares the features of Cypress S34ML-1 and S34ML-2.
Please let me know if you have further confusion.
Thanks and Regards,
