Hello ,this has been my process :

1.Enable password at OTP ,then setting 00000000000000000000000000000000 over a new imx pcb works ok with default OTP key (0)

2.Then i set my password at the OTP registers …

in elftosb I added pasword (this example with human readable

string, .. NOTE : i used HEX values at real password like freescale docs refers

and in HW_OCOTP_CRYPTO0:

this_is_

HW_OCOTP_CRYPTO1:

my_passw

HW_OCOTP_CRYPTO2:

ord_leng

HW_OCOTP_CRYPTO3:

ht_32_by

I am using right format for HW_OCOTP_CRYPTOx .. ?

What's my problem ?

After this i use elftosb to encrypt my boot loader + kernel but my pcb imx doesn't boot and i'm not able of watch fuses with bit burner (cause the blow surely)

what's my fail? someone knows a proper method for password and boot loader + kernel encryption ?

HEEEEEELPPPPP!!!!

After burn secuity fuse, bit burner can't work because there are firmware in bitburn, which can't run because security key mismatch.

Please make sure order of key. I can't remember it is big-endian and little endian.

You can revert byte order, and use elfttosb generate sb again
