PX4_simple_app not in Builtin App List?

[KochC]

Hey, I try to create an own application for my DroPix, so I started with the "Hello Sky" Tutorial. First my compiler wants a CMakeList.txt file which is not described in the tutorial, but I was able to create one on my own 😆

px4_simple_app.c

#include <px4_config.h>
#include <px4_tasks.h>
#include <px4_posix.h>
#include <unistd.h>
#include <stdio.h>
#include <poll.h>
#include <string.h>

#include <uORB/uORB.h>
#include <uORB/topics/sensor_combined.h>
#include <uORB/topics/vehicle_attitude.h>

__EXPORT int px4_simple_app_main(int argc, char *argv[]);

int px4_simple_app_main(int argc, char *argv[])
{
    PX4_INFO("Hello Sky!");

    return OK;
}

CMakeLists.txt

px4_add_module(
    MODULE examples__px4_simple_app
    MAIN px4_simple_app
    STACK_MAIN 2000
    SRCS
        px4_simple_app.c
    DEPENDS
        platforms__common
    )

nuttx_px4fmu-v2_default.cmake

# Tutorial code from
# https://px4.io/dev/px4_simple_app
examples/px4_simple_app

Compiler prints correctly compiled:

-- To change the version modify the file configure.ac

and the upload seems to work:

but I do not have the px4_simple_app in my Builtin Apps now:

Where is my fault? 😩🤔

[dagar]

It's probably my fault, not yours. For now try make distclean then build and upload again. There's a problem with the dependencies for the nuttx builtin apps generation.

[KochC]

nope, still not in the Builtin Apps list 😣 The folder px4fmu-v2_default/src/examples/px4_simple_app is correctly generated in the build directory. I also flashed via terminal and QGroundControl.

[KochC]

its still not possible to add any example to the Builtin Apps list. Is the tutorial wrong or is this bug?

[dagar]

Are you on the current firmware master?

This is working for me.

Ok, I hope thats it. Works now. Thanks a lot.
