TriCore emulation devices implement 1 lane Aurora interface. For these devices the selection is disabled and forced to 1. Selection of lanes depends on the TriCore device used, but may be additionally limited if only a portion of lanes is physically connected to the Aurora trace port connector on the target board.

Note that you have to select Aurora Trace Port in Hardware | CPU Options | Analyzer for Aurora interface use.

Number of lanes

Select the number of lanes available for the Aurora trace. This selection depends on the microcontroller you are using, as well as your target board design.

Lane link speed

Select the highest possible baudrate that still works on your target board. It is best if you start with the higher baudrates and then switch to lower ones until you get a stable trace line connection.

By default the lowest Aurora link speed is set which ensures the most likely working trace operation. Note that this setting directly impacts on Aurora trace interface bandwidth. The higher the speed, more trace information per time unit can be broadcasted over the interface. Hence, once the Analyzer trace operation is confirmed with the default setting, higher Aurora link speeds should be tested and the highest operational speed then selected for usage. This way the Active Probe will be configured for maximum possible Analyzer session time.
