Agent Debug Probe: an RP2040 probe that gives agents power, reset, SWD and UART

Agent Debug Probe connects a coding agent to a target through an RP2040 probe and MCP adapter. The agent can switch target power and USB data, drive reset and boot straps, and use SWD/JTAG and UART. A validation report dated 8 August logs bench tests of the fabricated board, including an 8.66 MB UART transfer to a Zynq target.

Briefing

The system has five parts: fail-safe RP2040 firmware, a single-owner host daemon, a Tauri and Vue desktop app, an MCP stdio adapter and a CLI. Besides switching and debug, it reads the target's identity and measures its power.

The 8 August report covers USB power-switch overcurrent shutdown and recovery, live RP2040 SWD at up to 500 kHz, and four-wire JTAG and 1 Mbaud UART on an EBAZ4205 Zynq board. The 8.66 MB transfer used XMODEM with zero retries. Firmware 0.2.8 added an AUX warning at 2.5 A and shutdown at 3.0 A, checked with an electronic load.
