I am following the CST Code Signing Tool guide paragraph : running the hab4_pki_tree. script to create the Keys efuses bin data.

I don't know what I should answer to the question : 

– Do you want the SRK certificates to have the CA Flag set?
– Answer ‘y’ for a standard tree, ‘n’ for fast authentication tree.

Is fast authentication tree supported by iMX8m mini processor ?

Is there a place where they explain what this fast authentication for PKI tree is ?

Can I answer yes even if at the beginning I answered no to the question "Do you want to use an existing CA key ?"


thank you
