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.
