tfm_ns_fault_handler_callback is called when booting

[Replay]

Hi,

I have a problem where tfm_ns_fault_handler_callback is called when booting the system.

This results in arm_fault and k_sys_fatal_error_handler is called. The reason is 41.

I have upgraded to SDK v2.6.1

Custom board based on nrf9160-SIP

The project is based on a azure iot hub example.

This is the error log:

Hi,

The project is based on a azure iot hub example.

Did the project ever work before?

Hi,

Yes without any problem.

Here is the history:

Starting the project using 2.0.0, encountered a sdk problem. upgraded to 2.2.0 to resolve the issue.

Now using 2.2.0 without debugging enabled. A problem need more debugging information enabled.

When debug was enabled enabled the program would not start. Found a devzone post (cannot find it again) where other did encounter problems with enabling debugging on 2.2.0, when I upgraded to 2.6.1 to solve the debugging issue I meet the issue described above.

Hi again,

Okay, I have narrowed it down to, when the config is changed from SIZE_OPTIMIZATION to DEBUG_OPTIMIZATION, the system will never run the main app.

The TFM PM_PARTITION_SIZE changes as well:

-CONFIG_PM_PARTITION_SIZE_TFM=0xC000 - With debug disabled.
+CONFIG_PM_PARTITION_SIZE_TFM=0x10000 - With debug enabled.

Good find.

In this case, I have a guess:

TF-M uses UART1 to log. So you need to disable UART1 in DTS for your custom board.
If you have not disabled this, it may cause the errors you see.

Hi Sigurd,

I'm sorry for jumping around with this post, but I'm desperate to find any solution.

The main problem I rand into was enabling Seggers SystemView configs.

I thought I need to enable debugging, due to some warnings and build errors.

Now I'm convinced, that the warnings when enabling SystemView is due to the use of K_EVENT_DEFINE.

Some of the building log - Sorry for bad formatting. The code insert would not work..

I thought I need to enable debugging, due to some warnings and build errors.

So you no longer use DEBUG_OPTIMIZATION or?

Replay said:

Now I'm convinced, that the warnings when enabling SystemView is due to the use of K_EVENT_DEFINE.

How do you enable this? I need specifics

No, it seems not to be the issue.

CONFIG_SIZE_OPTIMIZATIONS=y
# CONFIG_SPEED_OPTIMIZATIONS is not set
# CONFIG_DEBUG_OPTIMIZATIONS is not set
# CONFIG_NO_OPTIMIZATIONS is not set

[Sigurd Hellesvik]

So if you build without those configurations, it works.
And with them, it does not work.

Right?

[Replay]

Yes if I build without these configurations, everything works fine.

# Enable Segger SystemView
CONFIG_STDOUT_CONSOLE=y
# enable to use thread names
CONFIG_THREAD_NAME=y
CONFIG_SEGGER_SYSTEMVIEW=y
CONFIG_USE_SEGGER_RTT=y
CONFIG_TRACING=y
# enable for post-mortem tracing
CONFIG_SEGGER_SYSVIEW_POST_MORTEM_MODE=n

I think it is due to the project uses CONFIG_EVENTS.

If I build with those configurations, I get build errors:

With those configurations, are you able to build for the DK, or do you get the same error then?

I am asking cause if you get the same for the DK I can try to reproduce.

[Replay]

If I create a new project using SDK version 2.2.0, and having this prj.config, with the target board nrf9160dk_nrf9160_ns, some build warnings will occur. The same as I get in my project.

prj.conf

CONFIG_EVENTS=y

# Enable Segger SystemView
CONFIG_STDOUT_CONSOLE=y
# enable to use thread names
CONFIG_THREAD_NAME=y
CONFIG_SEGGER_SYSTEMVIEW=y
CONFIG_USE_SEGGER_RTT=y
CONFIG_TRACING=y
# enable for post-mortem tracing
CONFIG_SEGGER_SYSVIEW_POST_MORTEM_MODE=n

[Sigurd Hellesvik]

I get build errors for that config in v2.2.0, but not in v2.4.2 or v2.6.1.
