Understanding Communication Flow between RD772BJBCANFDEVB, RD-K358BMU and RD33774CNC3EVB

Hi NXP Team,

We are evaluating the following NXP BMS evaluation boards:

While reviewing the available example software, we are unable to understand the complete communication flow between the BJB, BMU and CMU.

We would appreciate clarification on the following:

Overall communication sequence between the three boards.
CAN messages exchanged between them.
Signal flow from one board to another.
Which software modules/files implement this communication.
Whether any communication flow diagrams or architecture documents are available.

Any documentation or application notes explaining the software communication flow would be greatly appreciated.

Thank you.
