Debug and trace
The V2M‑Juno motherboard supports processor debug, P‑JTAG, 16‑bit and 32‑bit trace to enable sofware debug and trace in the Juno Arm® Development Platform SoC.
You connect a debug unit to the P-JTAG connector on the V2M‑Juno motherboard to run processor debug, P-JTAG.
NoteThe processor debug device can be any compatible debug unit, for example DSTREAM, or a compatible third-party debugger.
You connect a compatible trace port analyzer, for example DSTREAM, or a compatible third-party debugger, to the TRACEA‑SINGLE connector to run 16‑bit trace or to both the TRACEA‑SINGLE and TRACEB‑DUAL connector to run 32‑bit trace.
The following figure shows an overview of the V2M‑Juno motherboard debug and trace architecture.
