Aurora

Aurora trace is supported via ARM HSSTP II Active Probe, which is available for iC5700 On-Chip Analyzer.

 

Note that you have to select Trace Port in the 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.

 

Generate clock

HSSTP (High Speed Serial Trace Port) can use an external reference clock (REFCLK) to produce the desired high-speed trace clock. Provisions for this clock signal have been made on the connector (pins CLK+ and CLK-). If the reference clock source is available on your target board, this is not needed. Alternatively you can enable this option and iSYSTEM BlueBox will generate the reference clock signal for you.

 

Generate CRC

This option adds CRC generation to Aurora packets. Since this incurs extra trace data overhead, enable this option if trace results are suspect or so advised by iSYSTEM Technical support.
