Dear @Adrian_Gherca ,
I hope you are well. I have built a MBDT Can transmit model mimicking the Can Transmit 342 S32CT example model in the Simulink library. However, when I observe it in Freemaster, the status of the Can_Write module is 2, which means the buffer is full or busy. ( pleas see the attached image). I have also attached the file of my whole model. Could you please help me to see where the issue is? Many thanks, Xiaomei
