Hello, in the process of using MFR4310, channel A and B were configured in the tx slot, but in the actual work, channel A can communicate normally, but channel B has no data.The channel configuration and usage methods refer to the official routine.What might be the reason?Is it not supported by itself?

Please check that the FlexRay controller is configured to work in the dual channel mode and that the channel B is enabled. Please, see the FR_MCR register for more details. Especially FR_MCR.SCM and FR_MCR.CHA and FR_MCR.CHB configuration.
