@elkick now I’m wondering if I made a mistake when I took this photo, I believe that error message shot above came after trying to run this command:
mkdir BLDC cd BLDC git clone https://github.com/vedderb/bldc-bootloader.git bldc-bootloader cd bldc-bootloader make upload
There are some reports here, specifically this one, that make me wonder whether I have a hardware defect that is preventing the bootloader from being loaded, which might explain why it wasn’t successful at the factory that @onloop used:
“I’ve tried it with and without the USB cable connected. I suspect the “unable to connect” indicates a hardware error, presumably in my soldering, unless anyone has other ideas.”
