Set EX_SSS_BOOT_DO_ERASE to 0
If set to 1, all objects, which are handled by Secure chip except for predefined ones, are deleted when a client application starts. This breaks the logic of existing example, and functions "getbinkey", "erasekey", and "decryptaes" start to fail because a requested key is already removed when ex_sss_entry() is called.
