The debugger is USB 1.1 compatible for easy connection to a host. A local proxy server handles the USB connection and offers a TCP connection to a software debugger. The GNU debugger with optional graphical user interface, such as DDD, is supported.
Connect to the design under test with a 10 pin ribbon header. Debugger uses a 2×5 pin header with 0,1″ spacing. Use the following pinout:
- JTAG TCK
- JTAG TDO
- VCCIO JTAG
- JTAG TMS
- VCCIO UART
- UART RX
- UART TX
- JTAG TDI
The debugger is built around an USB dual core UART from Future technologies (http://www.ftdi.com). Extending the functionallity is possible by using the development environment from FTDI.
