A tutorial on how to set up Lauterbach for Xilinx ZYNQ Ultrascale+ MPSoC. ZCU102 is used in this documentation.
This tutorial covers normal debug and trace with analyzer. The board might run a standalone (bare-metal) application without an operation, or it might run an embedded linux. So this gives four situations.
| situation | status |
|---|---|
| normal debug + standalone | success |
| normal debug + embedded linux | success |
| trace with analyzer + standalone | success on demo |
| trace with analyzer + embedded linux | success |
In our project, the hardware for normal debug is PowerDebug PRO, and for trace with analyzer is PowerTrace-II AutoFocus-II. Even if no trace analyzer presents, the PowerDebug PRO can still perform trace. This type of trace is referred as On-Chip trace. Because the trace information generated by Embedded Trace Macrocells (ETM) is stored in the on-chip memory. ETB, ETF, ETR referred in some literatures are all On-Chip trace. Due to the limited size of the on-chip memory, the buffer would be filled up in no time, i.e. the trace can only record the information in a short period of time.
When using an analyzer, the trace information can be exported via the equipment, thus a much larger buffer. This is referred as Off-Chip trace. Trace-port interface units (TPIU) on board is used in this case. To do so, the hardware design has to be configured accordingly.
