does uvisor has the ability to write something in the flash?

as the issue, whether the box can write some information to the flash ,and how i can use the func to achieve it?

The issue names no files, tests, or entry points. Start by checking the uVisor public API and documentation for flash-write support and the constraints on storing information. Done requires a confirmed supported approach or a clearly scoped implementation and usage path.
