Free and open implementation of the CMSIS-DAP debugger firmware

This is a free and open implementation of the CMSIS-DAP debugger firmware.

Both SWD and JTAG protocols are supported. However JTAG was not well tested due to lack of good targets. If you have any issues with it - let me know and I'll try to help.

To create a CMSIS-DAP compliant debugger, your platform must: Implement USB HID (and raw bulk for CMSIS-DAP v2) device able to receive and send arbitrary payloads Provide configuration file dapconfig.h with definitions for hardware-dependent calls Call dapinit() at the initialization time Call dapprocessrequest() for every received request and send…
