Note that turning all these to ``y`` will produce an incredible amount of logging output. Set the level you want and
|
||||
the area you're interested in to ``y``, and the rest to ``n``, and then recompile. You can see the full list of
|
||||
debug feature areas in the file `debug.h <https://github.com/apache/incubator-nuttx/blob/master/include/debug.h>`__.
|
||||
The debug options are available under ``Build Setup`` > ``Debug Options``. You will most likely have to enable the
|
||||
following options:
|
||||
|
||||
Timestamps can be enabled by setting ``CONFIG_SYSLOG_TIMESTAMP=y``.
|
||||
* ``Enable Debug Features`` — selecting this will turn on subsystem-level debugging options, they will become visible
|
||||
on the page below. You can then select the ones you want.
|
||||
* ``Enable Error Output`` — this will only log errors.
|
||||
* ``Enable Warnings Output`` — this will log warnings and errors.
|
||||
* ``Enable Informational Debug Output`` — this will produce informational output, warnings, and errors.
|
||||
|
||||
You can then select from the subsystems that are available, Network, Scheduler, USB, etc. Note that you will need to
|
||||
separately enable the subsystem elsewhere in the ``menuconfig`` system. To see the ``CONFIG`` define that is set,
|
||||
use the arrow keys to highlight the subsystem (for instance, ``Network Debug Features``) and type '?'. This will show
|
||||
you that the C macro that is set is called ``CONFIG_DEBUG_NET``. ``debug.h`` defines the ``netinfo()`` logging
|
||||
function that will log output if this macro is set. You can search the source code for ``netinfo`` to see how it is
|
||||
used.

|

You can use the ``kconfig-tweak`` script that comes with the ``kconfig-frontends`` tools to quickly change debug settings,

for instance turning them on or off before doing a build:
|
||||
|
||||
.. code-block:: bash

.. code-block:: console
|

$ kconfig-tweak --disable CONFIG_DEBUG_NET

|

$ kconfig-tweak --enable CONFIG_DEBUG_NET
|
||||
$ make olddefconfig
|

You can put a bunch of these into a simple script to configure the logging the way you want:

.. code-block:: bash
|
||||
.. code-block:: console
|
||||

#!/bin/bash

Custom Debug Logging
|
||||
--------------------
|
||||
|
||||
Sometimes you need to see debug logs specific to your feature, and you don't want the rest of the built-in logs
|
||||
because they're either not relevant or have too much information. Debugging using logs is surprisingly powerful.
|
||||
|
||||
|
||||
You can add your own custom debug logging by adding the following lines to
|
||||
`debug.h <https://github.com/apache/incubator-nuttx/blob/master/include/debug.h>`__:
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
/* after the CONFIG_DEBUG_WATCHDOG_INFO block near line 721 */
|
||||
#ifdef CONFIG_DEBUG_CUSTOM_INFO
|
||||
# define custinfo _info
|
||||
#else
|
||||
# define custinfo _none
|
||||
#endif
|
||||
|
||||
You need to add the following line to your ``.config`` file:
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
CONFIG_DEBUG_CUSTOM_INFO=y
|
||||
|
||||
You would use it like this:
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
/* Custom debug logging */
|
||||
custinfo("This is a custom log message.");
