Crazyflie Bootloader Flasing: No DFU cable USB device available

Post by cboustead » Wed Feb 06, 2019 2:06 pm

I'm setting up PX4 on my Crazyflie 2.0. I'm having an issue trying to flash the bootloader using USB. I get the message "dfu-util: No DFU capable USB device available". The cable I am using is a Micro USB -> USB and then I'm using a USB -> USB-C for my Mac.

When I execute the command "dfu-util -l --list", no devices are found.

Can anyone confirm whether this issue is because I am using an adapter rather than a cable straight through?

To boot the stm32 in DFU mode you should press the power button about 5 seconds until the LED is blinking fast. You might need to click the button once more after that. Are you doing this procedure?

Yes, I have been putting it into the Bootloader mode. The LED is blinking fast.

Are you sure your cable is working for data? (for example usb cables shipped with USB batteries usually do not have the data lines cabled...).

For reference, I tried on our dev mac and without battery, I press the button, connect the USB cable and release the button when the LED blinks fast, I get the bootloader to appear in the system report:

I tried with a new data cable today. I do not see any bootloader appear in my system report. Any ideas?

Hold on, it's working! The "without battery" was the most important part for your comment. Thanks
