I'm working with MPC5775K now. There's a strange problem happened to me these days. The FLEXCAN module works well independently. And the RX and TX module can receive and transmit right messages. Similarly, the ENET module can work well independently. My problem is that the CAN module would never receive any message when I open both FLEXCAN and ENET. At first I called the ENET initialization function , and then I called the FLEXCAN initialization function. Could someone give me instructions about this problem please ?
