I'm using mpc5748g canfd module to receive lots of messages. But canfd module can't use Receive FIFO function.
Now I am using one buf such as buf to receive these messages(not rx interrupt), I found some messages that missing.
My project need to receive can2.0b messages and canfd messages from car's controllers through can bus. If there are not canfd messages, I can using RX FIFO interrupt function to receive messages in case of losing messages. But there are canfd messages(canfd cannot use FIFO function).
Here are my questions: Should I use Rx Interrupt function without FIFO? How can I configure registers?
Or if I don't need Rx Interrupt function to receive meesges,how can I configure registers?
