Hi, I have STM32F091RC board and I am using CAN interface to read CAN BUS data from car. CAN works when I am powering STM32 from USB port (U5V). When I try to power STM32 from car (with E5V port), I get error in can interface 0x000E0000.
What could be causing this error?
I tested car 5V adapter, it seems that it is giving ~4.6V instead of exact 5V, could this be the cause?
