[Dev] eFUSE ?

Hello,

The eFUSE decription in "Hi6220V100_Multi-Mode_Application_Processor_Function_Description.pdf" Chapter 1.6.1 and 1.6.2 is difficult to understand.

Are there any function on the platform that can be used as a "consumer unit switch" i.e. lock boot-code or similar ?

Do you know any memory that can be programmed once, i.e. store keys etc ?

Thanks, Stefan
