-The debugger uses an IEEE 1149-1 compliant JTAG TAP bus master to access on-chip
-debug functionality available on ARM7 and ARM9 based microcontrollers /
-system-on-chip solutions.
-
-User interaction is realized through a telnet command line interface and a gdb
-(The GNU Debugger) remote protocol server.
-
-Initially, support for two JTAG TAP bus master interfaces with public hardware
-schematics will be included, but support of additional hardware is an expressed
-goal.
-
-1. JTAG hardware
-
-Currently, openocd contains support for Wiggler-compatible paralell port
-dongles and a USB interface based on the FTDI FT2232, called USBJTAG-1.
-A new version of the USB interface, USB-JTAG v1.2, is available with complete
-schematics (http://www.fh-augsburg.de/~hhoegl/proj/volksmikro/usb-jtag/050910/).
-
-It was tested using Amontec's (www.amontec.com) Chameleon POD in it's
-Wiggler configuration, but homemade wigglers should work just as well.
-In order to use the reset functionality (warm-reset, debug from reset, reset
-and init), the choosen Wiggler has to connect the nSRST line.
-
-USBJTAG-1 is based on a FTDI DLP2232M module and a few additional parts.
-Schematics are freely available. USB-JTAG v1.2 doesn't use the DLP2232M, but
-has the FTDI chip soldered directly on the PCB. There are two drivers for these
-modules implemented, one using the open source libftdi, the other using FTDI's
-proprietary FTD2XX library.
-
-2. Supported cores
-
-This version of openocd supports the following cores:
-
-- ARM7TDMI
-- ARM9TDMI
-
-Support for cores with MMUs (ARM720t, ARM920t) is currently being merged.
-
-3. Licensing
