11.4.4.2. Embedded Trace Router

The ETR can route trace data to the HPS on-chip RAM, the HPS SDRAM, and any memory in the FPGA fabric connected to the HPS-to-FPGA bridge. The ETR receives trace data from the AMBA* Trace Bus Replicator. By default, the buffer to receive the trace data resides in SDRAM at offset 0x00100000 and is 32 KB. You can override this default configuration by programming registers in the ETR.
