JIM-Tcl commands, and (older) the orginal command interpreter.
@item @b{Commands}
-@* At the OpenOCD telnet command line (or via the GDB mon command) one
+@* At the OpenOCD telnet command line (or via the GDB monitor command) one
can type a Tcl for() loop, set variables, etc.
Some of the commands documented in this guide are implemented
as Tcl scripts, from a @file{startup.tcl} file internal to the server.
List the debug adapter drivers that have been built into
the running copy of OpenOCD.
@end deffn
+@deffn Command {interface transports} transport_name+
+Specifies the transports supported by this debug adapter.
+The adapter driver builds-in similar knowledge; use this only
+when external configuration (such as jumpering) changes what
+the hardware can support.
+@end deffn
+
+
@deffn Command {adapter_name}
Returns the name of the debug adapter driver being used.
No arguments: print status.
@end deffn
-@end deffn
+@section Transport Configuration
+As noted earlier, depending on the version of OpenOCD you use,
+and the debug adapter you are using,
+several transports may be available to
+communicate with debug targets (or perhaps to program flash memory).
+@deffn Command {transport list}
+displays the names of the transports supported by this
+version of OpenOCD.
+@end deffn
+
+@deffn Command {transport select} transport_name
+Select which of the supported transports to use in this OpenOCD session.
+The transport must be supported by the debug adapter hardware and by the
+version of OPenOCD you are using (including the adapter's driver).
+No arguments: print selected transport..
+@end deffn
+
+@subsection JTAG Transport
+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),
+each of which must be explicitly declared.
+JTAG supports both debugging and boundary scan testing.
+Flash programming support is built on top of debug support.
+@subsection SWD ransport
+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.)
+@subsection SPI ransport
+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.

@deffn Command {flash info} num
Print info about flash bank @var{num}
The @var{num} parameter is a value shown by @command{flash banks}.
-The information includes per-sector protect status, which may be
-incorrect (outdated) unless you first issue a
-@command{flash protect_check num} command.
+This command will first query the hardware, it does not print cached
+and possibly stale information.

@end deffn
-@deffn Command {flash protect_check} num
-Check protection state of sectors in flash bank @var{num}.
-The @var{num} parameter is a value shown by @command{flash banks}.
-@comment @option{flash erase_sector} using the same syntax.
-This updates the protection information displayed by @option{flash info}.
-(Code execution may have invalidated any state records kept by OpenOCD.)

@anchor{Flash Driver List}
@section Flash Driver List
As noted above, the @command{flash bank} command requires a driver name,
@end deffn
@end deffn
+@deffn {Flash Driver} virtual
+This is a special driver that maps a previously defined bank to another
+address. All bank settings will be copied from the master physical bank.
+
+The @var{virtual} driver defines one mandatory parameters,
+
+@itemize
+@item @var{master_bank} The bank that this virtual address refers to.
+@end itemize
+
+So in the following example addresses 0xbfc00000 and 0x9fc00000 refer to
+the flash bank defined at address 0x1fc00000. Any cmds executed on
+the virtual banks are actually performed on the physical banks.
+@example
+flash bank $_FLASHNAME pic32mx 0x1fc00000 0 0 0 $_TARGETNAME
+flash bank vbank0 virtual 0xbfc00000 0 0 0 $_TARGETNAME $_FLASHNAME
+flash bank vbank1 virtual 0x9fc00000 0 0 0 $_TARGETNAME $_FLASHNAME
+@end example
