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:
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 ?
