Binho Atira

In this guide: Setup · Hardware reference · Protocols · Firmware · FAQ · Troubleshooting

Summary

The Binho Atira is a USB debug probe for Arm Cortex-M microcontrollers. One probe provides:

SWD debug: attach, halt, run, step, read and write registers and memory, hardware breakpoints.
Target flashing: the Atira is a CMSIS-DAP probe, so stock pyOCD programs the target’s internal flash.
Target power: a switched 3.3 V rail on the debug header, with voltage, current and power readings.
SPI controller and SPI NOR flash programming: detect, erase, program and verify an external 25-series flash.
USB-to-UART bridge: an ordinary serial port on the computer.

Drive it from the Mission Control 3 desktop app (MCU Programmer and MCU Debugger), from Python with PyCosmicSDK 1.7.0 or newer, from C/C++ with CosmicSDK 1.7.0 or newer, or from pyOCD for flashing.

Software

Software	Version	What it covers
PyCosmicSDK (Python)	1.7.0 and later	`DebugProbe` (blocking) and `AsyncDebugProbe` (asyncio): power, SWD debug, SPI, SPI flash, UART bridge port
CosmicSDK (C/C++)	1.7.0 and later	`libdebugprobe` with C++ (`debugprobe/DebugProbe.hpp`) and C (`DebugProbe_API_c.h`) headers
Mission Control 3 (desktop app)	9.1 and later for device packs	MCU Programmer and MCU Debugger: flash, verify, erase, halt, step and set breakpoints, with no code. See Install a device pack
pyOCD	0.44.1 verified	Program, erase and read back the target’s internal flash

A probe and a Supernova or Pulsar can be open in the same Python process.
