Hi, currently using STM32F103R8T6.

CAN interface is connect like:
PB8 -> CAN_RX -> TJA1050
PB9 -> CAN_TX -> TJA1050

in void Setup I'm using:
bool ret = CANInit(CAN_500KBPS, 2); // CAN_RX mapped to PB8, CAN_TX mapped to PB9

What happens is that while debugging i notice that on this line, the while loop never ends.

Communication works ok outside this unit. Am i missing something?
