EMX CAN bus timing

Hi,

I am using the EMX to communicate with a TI controller, bitrate is 500K, CAN standard, the micro-controller has a CAN Clock of 30Mhz and TQ of 12 (T1=7, T2=2 on the micro-controller, meaning 75% SP), the only setup i managed to work with on the EMX side is this:
BRP = 12
T1 = 6
T2 = 5

RX is perfect (all messages, ~10 per second) but TX is not received at all by the micro-controller and I get BusOff error messages, i am using CAN2 channel with a 5V transceiver.

Any ideas?

Play with t1 and t2. Remove one from one side and add to other I mean.
