Colibri race fc No response from bootloader
The first thing that you have to be sure of is that you have the vcp drivers installed for the Colibri. The Colibri and other newer flight controllers are using a virtual com port to communicate via USB as opposed to older hardware that uses a cp210x serial to USB chip to communicate via USB.
You can download load and install the VCP drivers from the betaflight setup screen
If this is a QQ190 or a TBS Vendetta then you can use the TBS agent software to update the board. For more info see manual.qq190racingdrone.com
