A bit-bang implementation of the protocol used by CC Debugger.

ccdbg

A bit-bang implementation of the protocol used by CC Debugger.

If you, like me, don't have access to a CC Debugger but have access to a board with at least 3 GPIOs like a Raspberry Pi, ccdbg will suffice for your debugging and flashing needs.

ccdbg.c, ccdbg.h

The device-independent module and API.

ccdbg-device.h

The device-dependent interface specifying which functions or macros should be implemented. Those that need implementation are prefixed with ccdbgDevice_*.

ccdbg-rpi.cpp, GPIO.cpp, GPIO.h

The device-dependent module specifically for Raspberry Pi running Raspbian. GPIO4, GPIO0, and GPIO1 pins are used as reset, debug clock, and debug data pins, respectively.

Please refer to this link for the pinout.

ccdbg-main.c, intelhex.c, intelhex.h, Makefile

The stand-alone ccdbg utility. To build and run the utility in Raspberry Pi, simply execute make and sudo ./ccdbg, respectively.
