Stm32mp157 optee ETC panic 0 0 ECO 5.0.3

[MWoło.2]

Hello,

I encountered a problem with optee that I could not resolve due to a misunderstanding of debug information.

During boot up the board, I get the following debug log

and with Panic at the end. I have to admit that I don't see any trouble with the debug text above.

I also attached two dts files tf-a and optee and full log. 

The files were generated from the latest STMCubeIde 1.17.0 with the necessary supplementation.

Thanks for any help

Hello Michal,

In order to have some more information on what causes the panic, you can print the call stack. Please have a look at https://optee.readthedocs.io/en/latest/debug/abort_dumps.html.

This will heavily narrow down the search to the root cause.

Br,

Hi GatienC,

I think Your suggestion did not resolve my problem because in my debug-log.txt there are no records with just empty addresses or data dumps like

"E/TC:0  0x001044a8" 

 Besides in my log, I have no records like "E/TC" without the last 'panic'.

Can I find the example dts of optee for DK2 board or ED1.

In my opinion Cube generator did something improper or I defined something wrong in it.

BR,

Michal

[GatienC]

It most probably is linked to this but the backtrace will allow you to know which part of the code makes the platform panic.

Can you check in the "conf.mk" file in the build directory, that you have 

CFG_UNWIND=y

You can also set 

CFG_TEE_CORE_DEBUG=y

as well.

BR,

Gatien

[MWoło.2]

OK, I check and try new options and let You know soon.

Thanks for now.

BR,

My activity now is

[MWoło.2]

Finally, I resolved a panic problem. The problem was related to iwdg2. Cube generates an iwdg2 section but without providing information into 

&etzpc {

DECPROT(STM32MP1_ETZPC_IWDG2_ID, DECPROT_S_RW, DECPROT_UNLOCK)

}

When I change iwdg2 to iwdg1 cube put the above information for IWDG1. I'm not sure if it is a feature or a bug.

Now log look much better

I/TC: Secondary CI/TC: Secondary CPU 1 switching to normal world boot

Of course, there is still in the log some error but go up to the Kernel booting. Unfortunately stuck on the last line in the log and that's all. Do I need to add something special to the Kernel dts?

Shall I again add more debug logs to see a problem or it is something obvious I omit?

BR,

Michal

Hello Michal,

Be aware that only secure peripherals will have their driver probed in OP-TEE, as you have figured while fixing this issue. I don't think the CubeMX is supposed to omit the firewall configuration if you select OP-TEE AFAIK but the IWDG2 peripheral is non-securable on stm32mp15x platforms so it's normal that it was not generated. Only securable watchdog is IWDG1 on these platforms.

Please note that if you're using a peripheral in the secure world (hence configuring it as secure) you cannot expect the non-secure world to access it directly.

The error log in OP-TEE indicates that a service failed to initialize so I would try to fix or understand this before going further. Adding more debug log will hopefully allow you to identify the service that failed, so yes, I would add a higher log level in OP-TEE.

Regarding the freeze in the kernel, I would also add the early console on the kernel side to get some more information as well.

[MWoło.2]

Hi GatienC,

First, thanks for the explanation. I'm a newbie in the trust zone, optee, and other security-related topics. Understanding it at a minimal level is necessary to go further.

Regarding IWDG2 I misunderstand the checkbox in the cube

The checkbox does not always mean that the peripheral is secured. In the documentation, I found confirmation of what You wrote above.

Documentation source RM0436 Rev 6 page 1121

Now I understand how many things I do wrong, and what I should fix in my dts files.

Today, I am going to try to re-enable all debug features of OP-TEE to investigate why the kernel is not starting and to remove all OP-TEE errors, even if they do not affect the boot process.

BR,

Michal

After adding earlycon into the kernel param I get something like
