ctxLink

Wireless debug probe for ARM Cortex-M microprocessors

This project is coming soon. Sign up to receive updates and be notified when this project launches.


ctxLink is an open hardware, open firmware debugging probe, based on the Black Magic Probe (BMP), that supports Wi-Fi connectivity and battery powered operation. It implements SWD and JTAG interfaces for remote, cable-free programming and debugging of ARM Cortex-M microcontrollers. It is ideal for debugging mobile projects such as robotic devices and other embedded systems that are not always physically accessible.

Features

  • Usability
    • Open hardware and open source firmware based on the BMP
    • Uses built-in STM32 system bootloader for firmware updates
    • Compatible with Windows, Mac, and Linux
  • Debugging
    • Implements SWD and JTAG interfaces
    • Supports a wide range of ARM Cortex targets, including ST, Atmel, Nordic, NXP, and others
    • Includes a built-in GDB Server that can be used with a wide range of Integrated Development Environments (IDEs)
    • Supports a wide range of target voltages (1.7 V to 5 V)
  • Connectivity
    • Supports USB and Wi-Fi connections to the host computer
    • Wi-Fi can be configured using WPS or through http provisioning with a smartphone
  • Power
    • Can be powered from the target (3 V to 5 V targets only)
    • Can be used to power the target (up to 100 mA)
    • Can be powered by an optional LiPo battery
    • Battery can be charged through USB

Specifications

  • Microcontroller: STM32F401RE
  • Wi-Fi module: Microchip WINC1500
  • Physical: 89 mm x 33 mm, 4-layer PCB
