Hi @youxi 

How to update the Nvm key and the Master key?
- Standard Memory Update Protocol defined by SHE specification should be used. You can take a look at function MemoryUpdateProtocol() in HSE DEMO APP or in HSE examples.

Do I need super user rights?
- No, these rights do not apply to SHE Memory Update Protocol.

- I didn't find an example directly for SHE version, so it's just necessary to follow section 9.5 Request for Super User rights in the HSE FW RM.
