T2080 Secure Boot : Enqueuing to SEC error

[ganesh_sullad]

Hi,

We are seeing 0x700 in the scratch register SCRATCHRW2, which corresponds to ERROR_SEC_ENQ as per Trust 2.0 device ISBC error codes. 

What are the possible reasons this error will show up? Could you guide on this?

Few other details: 

Using custom image, generated RSA key pairs using CST, generated CSF, digital signature and loaded on the T2080RDB setup. Upon code execution the above observation was made. 

OTPMK is fused, no error observed on the Security Monitor registers. 

SRKH is updated through script(using debugger) with values given by CST tool. 

Let me know if additional details are necessary. 

Note: If require, i can share the NDA file number.

Please let customer check whether their SOC supports SEC engine?

Hi Yipingwang,

Using T2080RDB setup and DCFG_CCSR_SVR content is 85300011 which indicates “0000_0000_0000 T2080 without security” under the VAR_PER field.

Does it mean the T2080 reference development PC board here not having Security engine enabled?

If yes for the above one, What is the procedure to enable the SEC module in the T2080RDB setup?

Supporting snap is attached, which shows the RCW is booted from NOR FLASH and along with SVR, PVR.

Thank you,

Ganesh Sullad

Secure boot depends on SEC module.

Please try secure boot with chip that includes SEC engine.
