Hello to all. I noticed that in the latest release of firmware for the STM32F7 (v1.9.0) the example application FatFs_USBDisk no longer works. During any fs_open command, an error is generated, and the app halts.


This did not happen in the previous version of firmware for the STM32F7 (v1.7.0).


I saw in the product release notes that there was an upgrade of components to the entire FatFs structure. I tried to follow the new rules of operation for the new upgrade (i.e - use updated usbh_diskio files, set block size to 512, etc), but still can't get it to run properly.


The folder for the FatFs applications is \STM32Cube_FW_F7_V1.9.0\Projects\STM32F767ZI-Nucleo\Applications\FatFs\FatFs_USBDisk.


Can somebody verify that they are seeing the same errors as I am seeing here now with this newly upgraded FatFs structure?


Thanks so much!!!
