Hi @Severin Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.
As far as I know, LevelX does not hold any safety certifications such as TÜV or UL. LevelX is an add-on to FileX that provides wear leveling for flash memory devices. It is designed to work with FileX and ThreadX, which are both safety-certified real-time operating systems.
Update:
LevelX itself is not safety certified. Aside from ThreadX itself, the following middleware components are safety certified: NetX Duo, USBX, FileX and GuiX.
