Failed to enable tracking in Net subsys.

I found this in Zephyr 4.0.0 Release notes:

"Fixed compilation issues with networking and SystemView Tracing enabled."

See https://github.com/zephyrproject-rtos/zephyr/issues/79805

Edit:
Okay just by adding CONFIG_NETWORKING=y to the tracing sample the issue is present.

Old:

My bad thought I used the correct prj.conf file.

Issue can be replicated when combining the tracing sample and azure_iot_hub sample:

Here is a snippet from the .config from the tracing sample:

#
# Tracing Configuration
#
CONFIG_TRACING_SYSCALL=y
CONFIG_TRACING_THREAD=y
CONFIG_TRACING_WORK=y
CONFIG_TRACING_ISR=y
CONFIG_TRACING_SEMAPHORE=y
CONFIG_TRACING_MUTEX=y
CONFIG_TRACING_CONDVAR=y
CONFIG_TRACING_QUEUE=y
CONFIG_TRACING_FIFO=y
CONFIG_TRACING_LIFO=y
CONFIG_TRACING_STACK=y
CONFIG_TRACING_MESSAGE_QUEUE=y
CONFIG_TRACING_MAILBOX=y
CONFIG_TRACING_PIPE=y
CONFIG_TRACING_HEAP=y
CONFIG_TRACING_MEMORY_SLAB=y
CONFIG_TRACING_TIMER=y
CONFIG_TRACING_EVENT=y
CONFIG_TRACING_POLLING=y
CONFIG_TRACING_PM=y
# CONFIG_TRACING_NETWORKING is not set
# end of Tracing Configuration

and here is for the tracing sample where azure_iot_hub sample has been merged:

#
# Tracing Configuration
#
CONFIG_TRACING_SYSCALL=y
CONFIG_TRACING_THREAD=y
CONFIG_TRACING_WORK=y
CONFIG_TRACING_ISR=y
CONFIG_TRACING_SEMAPHORE=y
CONFIG_TRACING_MUTEX=y
CONFIG_TRACING_CONDVAR=y
CONFIG_TRACING_QUEUE=y
CONFIG_TRACING_FIFO=y
CONFIG_TRACING_LIFO=y
CONFIG_TRACING_STACK=y
CONFIG_TRACING_MESSAGE_QUEUE=y
CONFIG_TRACING_MAILBOX=y
CONFIG_TRACING_PIPE=y
CONFIG_TRACING_HEAP=y
CONFIG_TRACING_MEMORY_SLAB=y
CONFIG_TRACING_TIMER=y
CONFIG_TRACING_EVENT=y
CONFIG_TRACING_POLLING=y
CONFIG_TRACING_PM=y
CONFIG_TRACING_NETWORKING=y
CONFIG_TRACING_NET_SOCKETS=y
CONFIG_TRACING_NET_CORE=y
# end of Tracing Configuration

Note the difference in network tracing in the bottom of the configs.

You need to build using one of the prj_file_suffix.conf files instead of with the default prj.conf

The tracing sample from zephyr is building but "CONFIG_TRACING is not set" in the build folder .config.

[quote user="Replay"]It builds fine but I'm having a hard time to understand why the "CONFIG_TRACING is not set" in the build folder .config[/quote]

Of your sample or the tracing sample?

Hi Sigurd,

Thank you for your suggestion.

It builds fine but I'm having a hard time to understand why the "CONFIG_TRACING is not set" in the build folder .config

Hi,

Check out the tracing sample and its prj_sysview.conf config. Try to build that sample with that file.
