Px4-autopilot: drivers/platform/Kconfig' not found error.

[heshananupama]

Every time I try to build a firmware, it just end up with this error. I followed the web while building the firmware but it complains me about this. What would be the reason?

[dagar]

Which version of PX4 is this?

Try

make distclean
make px4_fmu-v4_default

[heshananupama]

its PX4 version: v1.11.0-beta2-38-g951969ba00 It didn't fix. Still the build just stop stating the same error :(

[dagar]

its PX4 version: v1.11.0-beta2-38-g951969ba00 It didn't fix. Still the build just stop stating the same error :(

Can you check the toolchain installation? Is that the default terminal and shell or something different? From the firmware checkout you can run ./Tools/setup/OSX.sh.

[heshananupama]

Its my mac terminal. After I run the shell script you said following is the output. But still the error is there.

[wanderzell]

I have same error. While trying to build a firmware for Kakute F7

Is there any places where one could just go and download the Firmware to flash and use? I spent entire evening on installing "developers toolchain". Yet my only intention was to install the firmware and try how it flies on a racer.

[wanderzell]

Ignore my last comment - found firmware downloads from https://github.com/PX4/Firmware/releases

Look for small link "Assets" where it has more than 2

Would help if all releases have builds for all targets. Will save people from wasted effort setting up development environment that they will never really use.

[dagar]

@heshananupama let's see if we can capture more targeted error output to find the problem. I can tell you it isn't a problem in general as we have automated Mac builds. http://ci.px4.io:8080/blue/organizations/jenkins/PX4_misc%2FFirmware-compile_mac/detail/master/1917/pipeline

make distclean
V=1 make px4_fmu-v4_default

[heshananupama]

@wanderzell where did you find the firmware file? I downloaded the source from assets but still could not figure out the place of the firmware

[heshananupama]

@dagar Do we need to export some environment variables before running the make command?
Following are the entire output that I am getting

@wanderzell where did you find the firmware file? I downloaded the source from assets but still could not figure out the place of the firmware

I ended up grabbing a build from v1.11.0 Beta 1 release (not the latest)

Latest release has only source code but If you scroll down a bit then you see that some releases have more assets attached - code and ready built firmwares.

[dagar]

@dagar Do we need to export some environment variables before running the make command?
Following are the entire output that I am getting

No you don't need to, but it's possible you have something already set that's breaking it.

Your python path is a bit surprising (/Library/Frameworks/Python.framework/Versions/3.8/bin/python3). We need to try and capture real error output from the failed make olddefconfig NuttX build step.

After the failed build is there a nuttx_olddefconfig.log in the build directory?

We might need to add some debugging here to see what's going on. https://github.com/PX4/Firmware/blob/1c0925a189990f29f21c8c3eb2bdd594d52cb984/platforms/nuttx/NuttX/tools/kconfig-conf#L16

@dagar Following is the output. So I had format my Laptop and reinstalled everything. Still the error is same.

The debugging line is already there in my kcongif-conf file

[heshananupama]

@wanderzell Thank you, I found the files under assets. However the file has a .px4 extension right? How would we create the .hex file or the .bin file that could be uploaded to Microcontroller.

Hi,

I am running linux (manjaro) and I am having exactly the same problem when trying to build the kakute F7 firmware. I was trying to build from master, commit: af5c48b8699b8ef1ee274e0268678fb0dd7db212

In particular, I get:

Update 1: I tried building version 1.10.2 and did not have this problem
Update 2: It worked with the docker image
