Open on-chip JTAG debug solution for ARM and MIPS systems
OpenOCD is an on-chip debugging, in-system programming and boundary-scan testing tool for ARM and MIPS systems.
The debugger uses an IEEE 1149-1 compliant JTAG TAP bus master to access on-chip debug functionality available on ARM based microcontrollers or system-on-chip solutions. For MIPS systems the EJTAG interface is supported.
User interaction is realized through a telnet command line interface, a gdb (the GNU debugger) remote protocol server, and a simplified RPC connection that can be used to interface with OpenOCD's Jim Tcl engine.
This is the D2XX version based on the static FTDI D2XX library for Linux.
