MPC5775K FlexCAN and ENET

[ronliu]

Hi all,

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 ?

Thanks.

Best regards,

Ron

Hi Ron,

check if you do not use any pin for FlexCAN and Ethernet together. It is possible you initialize pins correct if you use modules independently, but when you combine modules you can overwrite the configuration. It is the only one I have.
