Default Zephyr Peripheral Mapping:

  • UART_5 TX/RX : P2 (DAPLink USB-C)

  • UART_5 TX/RX : P8 (DAPLink two position through hole)

  • LED1 : DS6 (Red)

  • LED2 : DS5 (Orange)

Programming and Debugging

The ADI SDP-K1 be programmed over USB using the DAPLink firmware running on an embedded NXP Freescale microcontroller or a 10-pin DEBUG header connected to a STLINK debugger.

DAPLink exposes a storage device, as well as USB HID and CDC Endpoints, to the host. For more details please refer to the Official DAPLink website.
