Hi,
in our application we use SDCard and USB stack with the following configuration:

The communication with the nRF5340 is done by using a Linux Embedded systems. When the device is connected to Linux, I copy a folder inside the SDCard without any problem.
When I remove the folder and put into a new one the copy fails and the linux systems told us that the memory was corrupted.
Instead, if I remove the folder directly from the OS (by removing the SDCard from the board with the nRF5340), and after that I write the folder by using the nRF5340 it works correctly.
The device are in production and we don't know how solve this issue!! Can you help us?
Best
Marco
