Hi.

I have been using solox sabresd board, part name is MCIMX6X4EVM10AC

And I found this RM.

i need to know the value of SEC_CONFIG[1:0]

I haven't boot this device yet.

 

How can I know SEC_CONFIG[1:0]?

According to part number naming, my board is security enabled.

So Boot Security setting is also Closed??

And according to this boot flow, if authenticate image is failed,

retry and retry download authenticated image.

It's confusing.

 

So this Boot Flow is only for Closed Boot security settings?

 

 

Thanks

Best regards

Phillip
