Yes thank you, calling unitialize before initializing solves the problem

Okay, here you go:
I tried to send can message from my GUI to the microcontroller using the function writeFD while the MCU's CAN is not configured, so i get an error in my gui which is normal saying that the chip is not in CAN bootloader mode.
