MFR4310 communication issue

Makabaka — Fri, 29 Jan 2021 02:27:33 GMT

Dear:

We have a project that uses MFR4310 and TJA1082 to communicate with FlexRay nodes.When sending data, the receiving node will detect the phenomenon that a frame of data is sent repeatedly occasionally, and the repeated data frames are not fixed.

Example of data transmission mode: in one time interval, two frames of data with ID 1 and 2 are first sent, then the ID are added 1, and the data with ID 3 and 4 are sent, and repeated successively.

So Data frames with Frame ID 1,2,3,4,5,6,7,8 are sent on the FlexRay bus.However, the receiving data will have Frame ID of 1,2,3,3,5,6,7,8 or 1,2,3,4,5,5,7,8. A frame is repeated and a frame is missed

At present, only one board appears this problem, do not understand the cause of this issue. Please help to analyze it.
