JTAG programmer and debugger for ARM microcontrollers with USB to RS-232 bridge.
The Turtelizer 2 open source hardware is based on the FT2232L. It is connected to the PC's USB port and provides two devices. The first one, a JTAG interface, is available at the 10-pin female plug, which fits to the Ethernut 3 JTAG port. OpenOCD is the recommended tool for flash programming and debugging. The second device can be used by the PC as a serial COM port, available at a standard DB-9 male connector.
The buffered JTAG interface supports target voltages from 1.65 V up to 5.5 V.
