I've acquired a few 4.12 Vesc with 2.18 firmware. Was able to reflash one using stlink. The other using the same process will not connect with usb or stlink. It will briefly connect stlink but before I can flash it disconnects. Unplug, wait a day and I get another 2 second window before it won't read again. Curious to know what the issue may be.
I've tried the canbus method, using the working vesc as an stlink, any other methods I might have missed ?
