Imx93 - Secure Boot

[aditya_h]

Hi,

I am exploring the secure boot feature in imx93 EVK with Win IoT. For generating keys and fusing the srk hash I followed the steps from  i.MX Windows 10 IoT User’s Guide (nxp.com).

Once the srk hash values are fused(device is not closed yet), ahab_status is giving this error,

=> ahab_status
Lifecycle: 0x00000008, OEM Open

        0x0287fad6
        IPC = MU APD (0x2)
        CMD = ELE_OEM_CNTN_AUTH_REQ (0x87)
        IND = ELE_BAD_KEY_HASH_FAILURE_IND (0xFA)
        STA = ELE_SUCCESS_IND (0xD6)

        0x0287fad6
        IPC = MU APD (0x2)
        CMD = ELE_OEM_CNTN_AUTH_REQ (0x87)
        IND = ELE_BAD_KEY_HASH_FAILURE_IND (0xFA)
        STA = ELE_SUCCESS_IND (0xD6)

Can anyone help me to understand what could be the reason for this error code?

Hello @aditya_h,

I hope you are doing well.

->If the fuses have been written properly, there should be no SECO events after boot.
Please make sure of it.

For more details please refer to the below link.
