Hi,
We have been trying to get CleanFlight to work with our FC, but have been struggling for the past few days. We have gotten the same aforementioned errors: "Failed to open Serial Port" and "No response from Bootloader, programming FAILED". We installed all of the proper drivers and have flipped the dip switches to the proper settings. I contacted a friend at a different school who is also participating in the Games, and he said he's been having the same issues. If anybody has any solutions, please let me know!
