As I mentioned in the title, I am designing a vesc75 / 300 based controller. There is a problem with my first prototypes that I cannot understand. PCB can successfully communicate with vesc tool. Real time data etc. I can reach parts. However, whenever I try to detect the motor, the connection is broken and the vesc resets itself when the power stage is supposed to work.

I think the problem is due to power stage. I suspect Mosfet drivers but not sure. If anyone has an idea, please share it with me

Thanks everyone!

I use IRF135B203 mosfets, UCC27211 mosfet drivers
