imx28 HAB event (0x33 0x28 0xA 0x0)

[collinshi]

Hello,

I have the HAB EVENT output in imx28 when runing Eboot:

dispay_hab_event ,hab_event_number=1

-----------------------------

   dispay_hab_event ,hab_event_length=0x8

    0xDB 0x0 0x8 0x40 0x33 0x28 0xA 0x0

-----------------------------

0x28 0xA in the HAB_API_UG means : HAB_INV_CALL: hab_rvt.entry() not run successfully prior to call

What does it mean ?

What can I do to fix it ?

my csf is:

[Header]
    Version = 4.0
    Hash Algorithm = sha256
    Engine Configuration = 0
    Certificate Format = X509
    Signature Format = CMS

    File = "../crts/SRK_1_2_3_4_table.bin"
# Specify the index of the SRK in the SRK Table
   Source index = 0

and IVT 'S self pointer is 0x8000 ,it is 32 Bytes.

Hello,

HAB_INV_CALL event occurs when  hab_rvt.entry() not run successfully prior to call.

Function hab_rvt.entry() initializes the HAB library and Security Hardware plugins.

Please refer to HAB API description for more details.

Have a great day,
Yuri

HI Yuri,

with the Mx28 Secure Boot ,after patching

the uboot_ivt.bd is :

where will the power_prep be loaded using  load power_prep; ?

why does load power_prep bin>0x10; should load the in to 0x10 ? Can we load it into other address such as 0x0010000 ?
