语法
userkeys = <filename>
文件格式
user_key0 <userkey0 value>
user_key1 <userkey1 value>
user_key2 <userkey2 value>
user_key3 <userkey3 value>
user_key4 <userkey4 value>
user_key5 <userkey5 value>
user_key6 <userkey6 value>
user_key7 <userkey7 value>
描述
指向用户密钥文件的路径。密钥文件包含用于加密分区的用户密钥。用户密钥的大小可以为 128 或 256 位。128 位密钥只能用于运行时加载的分区。
示例
在以下示例中，FPD 分区将密钥源用作 user_key2，因此该分区的 .nky 文件必须使用 userkeys 文件中的 user_key2 作为 key0。然后，Bootgen 使用 .nky 文件中的此 key0 进行加密。解密期间，PLM 将使用由 pmc_data 编程的 user_key2。
