An unknown SECO event occurred using i.MX8

[minsiklee]

Hi all,

When I do sc_seco_sab_msg(), the following seco event occurs.

Life cycle : 0x 80, OEM closed

SECO Event[0] = 0x C1F729

1. What does "addr: address of message block" mean among the two sc_seco_sab_msg() api parameters? (it mean the flash ram address?)

2. What does seco event 0xC1F729 mean?

If anyone knows what the event means and how it needs to be handled, that would be of great help.

Thank you

best regard.

Hi @minsiklee,

I hope you are doing well.

Please mention the scfw porting kit version and the Linux BSP version that you are using.

One can refer to 18.20 SECO: Security Controller Driver (Enumration ) in System Controller Firmware Porting Guide.

1. What does "addr: address of message block" mean among the two sc_seco_sab_msg() api parameters? (Does it mean the flash ram address?)

[Ans]: address of the message block refers to where the signed message block can be found.

Please make sure that you are using the latest scfw for Linux BSP used as shown in the below link.

Embedded Linux for i.MX Applications Processors

Hi @Dhruvit.

Thank you for your kind reply.

Linux BSP version and scfw porting kit version are used to support i.MX 8DXL.
(maybe, using Linux 5.4.70_2.3.0​, SCFW Porting Kit​ 1.10.0 or later version)

I would appreciate it if you could answer the question 2 I asked.
(2. What does seco event 0xC1F729 mean?)

Thanks,
Duncan.
