The HID endpoint creates a tunnel to the CPUs debug access port.


DAPLink has superseded the mbed CMSIS-DAP interface firmware project. The project is constantly under heavy development by Arm, its partners, numerous hardware vendors and the open-source community around the world. More features are planned and will show up gradually over time. DAPLink enables developers with drag-and-drop programming, a serial port and CMSIS-DAP based debugging. It creates a bridge between your development computer and the CPU debug access port. This configuration is found on nearly all development boards.

Commonly referred to as interface firmware, DAPLink runs on a secondary MCU that is attached to the SWD or JTAG port of the application MCU. Arm Mbed DAPLink is an open-source software project that enables programming and debugging application software on running on Arm Cortex CPUs.
