Not able to flash crazyflie drone.

[cuber-1]

I'm currently trying to run the crazyflie drone through my Windows computer. I'm not using a VM and am trying to install the firmware to my computer. I am using this link: https://www.bitcraze.io/documentation/repository/crazyflie-firmware/master/building-and-flashing/build/.
I am in the compiling section currently and have ran

$ make cf2_defconfig
$ make -j 12

The build was successful and showed CLEAN in the command prompt.

I am in this section now:

---

Automatically enter bootloader mode
Make sure the Crazyflie is on
In your terminal, run CLOAD_CMDS="-w [CRAZYFLIE_URI]" make cload
or run cfloader flash build/cf2.bin stm32-fw -w [CRAZYFLIE_URI] with [CRAZYFLIE_URI] being the uri of the crazyflie.

I've tried to run both the CLOUD_CMDS command and the cfloader flash command but neither works.

For CLOUD_CMDS:

For the cfloader, however, when I do "pip show cfloader", it shows:

What do I do?

Under WSL, the makefile tries to run the Windows python python.exe -m cfloader -w radio://0/80/2M flash cf2.bin stm32-fw. So you must make sure that cfclient is installed on the windows side by running pip install cfclient in a Windows shell or with pip.exe. This is the relevant part of the documentation: https://www.bitcraze.io/documentation/repository/crazyflie-firmware/master/building-and-flashing/build/#windows

I believe my cfclient is already installed on the windows side. I just type cfclient into no specified directory and the application pops open and works great. I've been able to connect and fly the drone before. Just to be safe I tried again:

Now that you bring this section up, however, I do remember doing something that could have an impact, but I'm not sure. In the Windows instructions, one part asks to follow the instructions made for Ubuntu. After I completed the Windows and Ubuntu instructions, I began to follow the instructions in compile section.

I ran the following:

root@NAME:/mnt/c/Users/NAME/crazyflie-firmware# make cf2_defconfig
make[1]: Entering directory '/mnt/c/Users/NAME/crazyflie-firmware/build'
  HOSTCC  scripts/basic/fixdep
/bin/sh: 1: gcc: not found
make[2]: *** [scripts/Makefile.host:91: scripts/basic/fixdep] Error 127
make[1]: *** [tools/kbuild/Makefile.kbuild:318: scripts_basic] Error 2
make[1]: Leaving directory '/mnt/c/Users/name/crazyflie-firmware/build'
make: *** [tools/kbuild/Makefile.kbuild:150: sub-make] Error 2

It said the gcc was not found, and ChatGPT said to run this

sudo apt install gcc

Everything worked fine after that, and the build showed CLEAN

Does this have anything to do with the issue?

[cuber-1]

Here is an update: I deleted all files and installed everything again. I tried flashing the sample code found here: https://www.bitcraze.io/documentation/tutorials/getting-started-with-development/. Here is what happens when I try to run the build:

I'm worried about the MODIFIED note here, but let me know if this is how it is supposed to be.

When I run the command to flash, this is what I get:

However, when I turn the drone on, the code I changed doesn't work. Rather than the M1 light changing from red to green, there is no light at all.

[evoggy]

If you revert your changes and build/flash again does it work?

[cuber-1]

It does work again if I build/flash again. The red light blinks at a continuous rate.

[evoggy]

So if I understand correctly if you make the change and flash it no LEDs go on (not even M2) but if you revert the changes everything works? If this is the case it a bit strange since M2 is controlled by the nRF so it should not be effected. Can you still scan/connect to the Crazyflie from the client if you flash the example changes?

[cuber-1]

Yes, it flies perfect. Just to make sure this wasn't a drone issue, I went ahead and installed the VM to see if anything different happens. The modified code works on the VM - the light flashes green instead of red. I'll describe a bit more of what I saw on my Windows (WSL). both the M1 and M4 lights just didn't show at all.

[cuber-1]

Update: I unplugged the drone battery, plugged it back, turned the drone on, turned the drone off, held the power button to enter bootloader mode, and everything seems to work fine now. Thanks for all your help guys!

[evoggy]

Good to hear!
