Understanding Communication Flow between RD772BJBCANFDEVB, RD-K358BMU and RD33774CNC3EVB

Hi NXP Team,

We are evaluating the following NXP BMS evaluation boards:

  • RD772BJBCANFDEVB (BJB)
  • RD-K358BMU (BMU)
  • RD33774CNC3EVB (CMU)

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.
RD33774CNC3EVB , RD-K358BMU , RD772BJBCANFDEVB
