Embedded DAP42 Debug Probe

This is the version of DAP42 used with SushiBits One version 7 and above.

Introduction

DAP42 is a CMSIS-DAP compatible USB JTAG debug adapter for ARM Cortex-A and Cortex-M processors, based on the STM32F042K6 microcontroller.

This project is inspired by the original DAP42 project. There are some additional features implemented on top of the original project:

• Full JTAG support. This is useful in a daisy-chained JTAG scenario.
• Built-in USB serial adapter for communication and ISP.
• Control on the BOOT0 pin of the target chip for entering ISP.
