SD-CARD implementation with SDMMC and FatFS

[bhoppe]

Hello,

i have a question concerning the SD-Card functionality and the licensee fee of the SDMMC implementation of the STM32H723ZG.
My goal is to log some data on the card. According to the documentation, the FatFs-Filesystem can be used under a BSD-style license. How About the SDMMC Protocol? The SD Association states that a licensee fee must be paid if you plan to develop a host device. Has this fee already been paid with the purchase of the STM32?

Hello,

Already paid by the silicon manufacturer, so use it without any issue.
