my VESC 4.12 suddenly stopped moving the motor mid driving.
All LED’s are lighting up (without blinking) when the power is connected. It is not communicating over UART anymore.
Furthermore, the connection to the VESC tool is not working (tried different cables and different PC’s). (Device is not found)
I do not see any visual damage to the components.

Unfortunately, the focus of my camera is limiting the image quality…
I’ve checked like 100 times, if the cables soldered to the UART ports have a shortage - they don’t.
There are three LEDs on my VESC: Blue, Green and Red - all of them light up
Well… I’ve used my board on rough terrain - but without me driving on it. Due to the low friction, it only went at about 5km/h for a few meters. Then it stopped working. So the vibration are responsible?
I think you messed up your bootloader and require you to reflash the firmware.
You can do this with Stlink v2 or using another VESC to reflash the broken vesc (you will need vesc with firmware 3.57 or above. There will be an option in VESC Tool called SWD prog to reflash a vesc with another vesc).
I had a big issue with two of my vescs and i contacted a guy called Martin who is fixing them for me, 35euro to fix ans ship back. If the StLink doesnt work (it didnt with mine) i recommend sending them to him. PM me and i can send his email over if you need it.
