  3. openocd \- A free and open on\-chip debugging, in\-system programming and
  4. boundary\-scan testing tool for ARM and MIPS systems
  5. .SH "SYNOPSIS"

  7. .SH "DESCRIPTION"
  8. .B OpenOCD
  9. is an on\-chip debugging, in\-system programming and boundary\-scan
  10. testing tool for various ARM and MIPS systems.
  11. .PP
  12. The debugger uses an IEEE 1149\-1 compliant JTAG TAP bus master to access
  13. on\-chip debug functionality available on ARM based microcontrollers or
  14. system-on-chip solutions. For MIPS systems the EJTAG interface is supported.
  15. .PP
  16. User interaction is realized through a telnet command line interface,
  17. a gdb (the GNU debugger) remote protocol server, and a simplified RPC
  18. connection that can be used to interface with OpenOCD's Jim Tcl engine.
  19. .PP
  20. OpenOCD supports various different types of JTAG interfaces/programmers,
  21. please check the \fIopenocd\fR info page for the complete list.
