CAN peripheral crashes when using very low baud rates on stm32f4.

[Vde P.1]

I'm trying to transmit CAN messages with the stm32f4 from CAN2 to CAN1 (using a transceiver and so on). I'm trying to put the baud rate at arround 1khz so I can watch it using my arduino as an oscilloscope (which is able of performing 3666 samples per second). But when doing so HAL_CAN_AddTxMessage works sometimes and other fails with param error. Does anybody know which is the minimum baudrate allowed by bxCAN?

Nevermind, I think that I have CAN1 pins blown up
