Make cload Error

[kul46]

Hello, I am using Ubuntu 24.04.01 LTS and installed the cfclient and firmware. However, on following the "Getting started with development" doc I am getting this error when I use the last "make cload" command. Would really appreciate any help to flash the firmware successfully.

Hi @kul46 !
Thank you for the detailed description of you issue, this helps a lot when trying to find the root cause!
It looks like the Crazyradio is not found for some reason. There could be several reasons for this.
It could be a crazyradio software issue, is the radio behaving normally when connecting and communicating with the Crazyflie?
Is the radio connected via a dock?

I would also try updating my libusb library. It looks like it old be old, based on the deprecation warnings.

Hello! Thank you for your reply!

I got the Crazyradio to connect to the Crazyflie and send python scripts. They work. However, after I send one script, to send another one I have to wait for the program to end then remove the radio, restart the crazyflie, and execute another script. I am not sure if that is normal but removing and reconnecting the Crazyradio/restarting the Crazyflie everytime I want to reconnect to cfclient or upload another script seems redundant.

Additionally, while the radio is transmitting and the crazyflie is executing scripts well, the warnings have still not disappeared:

Also, for some reason the ".takeoff()" command kept sending an error that the drone is "Already Flying" that I had to bypass using a try/catch statement.

I did try to update my libraries but the notices have not disappeared:

Is my hardware faulty or is there something else to this issue? Really appreciate your help. I need to get the radio to be able to transmit two scripts at the same time while one is running but it cant as I need to remove and reconnect and restart the drone for every individual script.
