NAME

       openocd - A free and open on-chip debugging, in-system programming and boundary-scan testing tool for ARM
       and MIPS systems

SYNOPSIS

       openocd  [-fsdlcphv]  [--file  <filename>]  [--search  <dirname>]  [--debug  <debuglevel>]  [--log_output
       <filename>] [--command <cmd>] [--pipe] [--help] [--version]

DESCRIPTION

       OpenOCD is an on-chip debugging, in-system programming and boundary-scan testing tool for various 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.

       OpenOCD  supports  various  different types of JTAG interfaces/programmers, please check the openocd info
       page for the complete list.

OPTIONS

       -f, --file <filename>
              This is a shortcut for a -c "[script <filename>]"  command,  using  a  search  path  to  load  the
              configuration  file  <filename>.   In order to specify multiple config files, you can use multiple
              --file arguments. If no such -c options are included, the first config  file  openocd.cfg  in  the
              search path will be used.

       -s, --search <dirname>
              Add  <dirname>  to the search path used for config files and scripts.  The search path begins with
              the current directory, then includes these additional directories before other components such  as
              the standard OpenOCD script libraries.

       -d, --debug <debuglevel>
              Set debug level. Possible values are:
                * 0 (errors)
                * 1 (warnings)
                * 2 (informational messages)
                * 3 (debug messages)
              The default level is 2.

       -l, --log_output <filename>
              Redirect log output to the file <filename>.  Per default the log output is printed on stderr.

       -c, --command <cmd>
              Add  the  command <cmd> to a list of commands executed on server startup.  Note that you will need
              to explicitly invoke init if the command requires access to a target or flash.

       -p, --pipe
              Use pipes when talking to gdb.

       -h, --help
              Show a help text and exit.

       -v, --version
              Show version information and exit.
