iMX8M HAB

Hi,

 

I'll start with the bottom line. I followed a document, received from NXP, for applying HAB on iMX8M processor. After updating the signed boot image and running "hab_status" command I receive the following:

 

Secure boot disabled
HAB Configuration: 0xf0, HAB State: 0x66

As you can see, on one hand I don't see any event printed but on the other hand I also don't see the  following typical message you see on a successful secure boot:

No HAB Events Found!

This leaves me with a question regarding the real status.

 

I must say that the document I'm following, seems to be in early stages of wring and far from a formal document you can find for iMX6, for example. In this document, there are references to figures that don't exist in the document. Some of the figures contain information that is referenced later. Specifically it can be found when generating CSF files and updating the relevant HAB blocks. I believe I was able to fill this gap of information, but there is some doubt here.

 

So to conclude:

1. Is it OK or not, that I don't see " No HAB Events Found!" message?

2. Do you have an updated and more complete version of the document?

 

Thanks,

Eli.
