SiFive-ARTY Trace Adapter
The SiFive-ARTY Trace Adapter allows debug and trace connections between the J-Trace and the ARTY board running SiFive RISC-V core bitstreams.
Overview
The SiFive-ARTY Trace Adapter allows debug and trace connections between the J-Trace and the ARTY board running SiFive RISC-V core bitstreams.
The ARTY board provides several identical headers where the JD header is used as the debug connector and the JC header as the trace connector when running SiFive RISC-V bitstreams on the ARTY board that have trace enabled.
