@section Transport Configuration
+@cindex Transport
As noted earlier, depending on the version of OpenOCD you use,
and the debug adapter you are using,
several transports may be available to
@end deffn
@subsection JTAG Transport
+@cindex JTAG
JTAG is the original transport supported by OpenOCD, and most
of the OpenOCD commands support it.
JTAG transports expose a chain of one or more Test Access Points (TAPs),
JTAG supports both debugging and boundary scan testing.
Flash programming support is built on top of debug support.
@subsection SWD Transport
+@cindex SWD
+@cindex Serial Wire Debug
SWD (Serial Wire Debug) is an ARM-specific transport which exposes one
Debug Access Point (DAP, which must be explicitly declared.
(SWD uses fewer signal wires than JTAG.)
SWD is debug-oriented, and does not support boundary scan testing.
Flash programming support is built on top of debug support.
(Some processors support both JTAG and SWD.)
+@deffn Command {swd newdap} ...
+Declares a single DAP which uses SWD transport.
+Parameters are currently the same as "jtag newtap" but this is
+expected to change.
+@end deffn
+@deffn Command {swd wcr trn prescale}
+Updates TRN (turnaraound delay) and prescaling.fields of the
+Wire Control Register (WCR).
+No parameters: displays current settings.
+@end deffn
+
@subsection SPI Transport
+@cindex SPI
+@cindex Serial Peripheral Interface
The Serial Peripheral Interface (SPI) is a general purpose transport
which uses four wire signaling. Some processors use it as part of a
solution for flash programming.
@emph{JTAG TAP Reset} ... the @emph{TRST} hardware signal resets
just the TAP controllers connected to the JTAG adapter.
Such resets should not be visible to the rest of the system; resetting a

@item
@emph{Emulation Reset} ... many devices can be reset through JTAG
commands. These resets are often distinguishable from system
when either of those signals is not connected.
When SRST is not available, your code might not be able to rely
on controllers having been fully reset during code startup.
-Missing TRST is not a problem, since JTAG level resets can

be triggered using with TMS signaling.
@item @emph{Signals shorted} ... Sometimes a chip, board, or
current target. Must be preceeded by fast_load_image.
@end deffn
-@deffn Command {fast_load_image} filename address [@option{bin}|@option{ihex}|@option{elf}]
+@deffn Command {fast_load_image} filename address [@option{bin}|@option{ihex}|@option{elf}|@option{s19}]
Normally you should be using @command{load_image} or GDB load. However, for
testing purposes or when I/O overhead is significant(OpenOCD running on an embedded
host), storing the image in memory and uploading the image to the target
@end deffn
@anchor{load_image}
-@deffn Command {load_image} filename address [[@option{bin}|@option{ihex}|@option{elf}] @option{min_addr} @option{max_length}]
+@deffn Command {load_image} filename address [[@option{bin}|@option{ihex}|@option{elf}|@option{s19}] @option{min_addr} @option{max_length}]
Load image from file @var{filename} to target memory offset by @var{address} from its load address.
The file format may optionally be specified
-(@option{bin}, @option{ihex}, or @option{elf}).
+(@option{bin}, @option{ihex}, @option{elf}, or @option{s19}).
In addition the following arguments may be specifed:
@var{min_addr} - ignore data below @var{min_addr} (this is w.r.t. to the target's load address + @var{address})
@var{max_length} - maximum number of bytes to load.
