HAB on iMX6

[saisuryanarayan]

Hi yuri,

Thanks for your reply.

Now my HAB status is not giving any events.Now i want to know what happens

exactly if make *SEC_CONFIG *fuse to closed.You said it is not recommended

to close it.my doubts are,

If close the SEC_CONFIG fuse can i change the u-boot in my boot device(*u-boot

signed with same keys*) ?

Is there any silicon problems comes in closed mode with signed u-boot?

If i close the fuse and if any authentication problem comes and board is

not booting then how to recover it ?

Thank You

With Warm Regards,

1.

   Yes, customers can change the u-boot in boot device ( with same keys) .

2.

  As for close configuration, please pay attention on section 6.3 (Unlocking the RNG

on i.MX 6 Series) of the app note AN4581.

  If (SRK) fuses are "not broken" - it is possible to re-write boot image again.

Have a great day,
Yuri.
