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