AWR6843: CAN_FD Timing Parameter calculation AWR6843

Franz Schmid

Part Number: AWR6843
Other Parts Discussed in Thread: AWR1642

The CLK of MCAN module is at 80MHz so that the timings parameters need to be changed in TimingParams

Using the tooling of PeakSystems he defined following parameter:

Bit Rate Calculation Tool: PEAK-System (peak-system.com)

How to calculate the propagation time segment. Timings depend on hardware (Transceiver) and of the CAN Bus topology. The apps not swru520e shows only information about standard HighSpeedCAN.

Can you please support the configuration and calculations?
