New Revision: 2209

Modified:
   trunk/src/jtag/parport.c
Log:
Simplify and improve parport_handle_parport_port_command:
- Show the port number to the user when asking for it or setting it.
- Print an error if the parport_port has already been set.
- Use parse_u16 helper to ensure the parport_port string parses correctly.

David Brownell <da...@pa...>:

Rework the "Simple Configuration Files" chapter so it's more
of a quick-start "how to set up your project" tutorial:

 - Say how to hook up the JTAG adapter.  This will help new
   users, and in any case is worth spelling out somewhere.

 - Streamline the previous rather haphazard presentation,
   filling in some missing holes along the way:

     * Suggest "project directory" structure
     * Introduce new term, "user config" file (openocd.cfg)
     * Talk about more options for openocd.cfg contents
     * ... and about creating new config files
     * Add new topic, project-specific utilities (+examples)

 - Remove too-short, yet duplicative, chapter 19

Nudge packagers a bit more strongly to send patches (including
config files) upstream.

-@chapter Simple Configuration Files
-@cindex configuration
+@node OpenOCD Project Setup
+@chapter OpenOCD Project Setup
 
-@section Outline
-There are 4 basic ways of ``configurating'' OpenOCD to run, they are:
+To use OpenOCD with your development projects, you need to do more than
+just connecting the JTAG adapter hardware (dongle) to your development board
+and then starting the OpenOCD server.
+You also need to configure that server so that it knows
+about that adapter and board, and helps your work.
 
+@section Hooking up the JTAG Adapter
+
+Today's most common case is a dongle with a JTAG cable on one side
+(such as a ribbon cable with a 10-pin or 20-pin IDC connector)
+and a USB cable on the other.
+Instead of USB, some cables use Ethernet;
+older ones may use a PC parallel port, or even a serial port.
+
 @enumerate
-@item A small openocd.cfg file which ``sources'' other configuration files
-@item A monolithic openocd.cfg file
-@item Many -f filename options on the command line
-@item Your Mixed Solution
+@item @emph{Start with power to your target board turned off},
+and nothing connected to your JTAG adapter.
+If you're particularly paranoid, unplug power to the board.
+It's important to have the ground signal properly set up,
+unless you are using a JTAG adapter which provides
+galvanic isolation between the target board and the
+debugging host.
+
+@item @emph{Be sure it's the right kind of JTAG connector.}
+If your dongle has a 20-pin ARM connector, you need some kind
+of adapter (or octopus, see below) to hook it up to
+boards using 14-pin or 10-pin connectors ... or to 20-pin
+connectors which don't use ARM's pinout.
+
+In the same vein, make sure the voltage levels are compatible.
+Not all JTAG adapters have the level shifters needed to work
+with 1.2 Volt boards.
+
+@item @emph{Be certain the cable is properly oriented} or you might
+damage your board.  In most cases there are only two possible
+ways to connect the cable.
+Connect the JTAG cable from your adapter to the board.
+Be sure it's firmly connected.
+
+In the best case, the connector is keyed to physically
+prevent you from inserting it wrong.
+This is most often done using a slot on the board's male connector
+housing, which must match a key on the JTAG cable's female connector.
+If there's no housing, then you must look carefully and
+make sure pin 1 on the cable hooks up to pin 1 on the board.
+Ribbon cables are frequently all grey except for a wire on one
+edge, which is red.  The red wire is pin 1.
+
+Sometimes dongles provide cables where one end is an ``octopus'' of
+color coded single-wire connectors, instead of a connector block.
+These are great when converting from one JTAG pinout to another,
+but are tedious to set up.
+Use these with connector pinout diagrams to help you match up the
+adapter signals to the right board pins.
+
+@item @emph{Connect the adapter's other end} once the JTAG cable is connected.
+A USB, parallel, or serial port connector will go to the host which
+you are using to run OpenOCD.
+For Ethernet, consult the documentation and your network administrator.
+
+For USB based JTAG adapters you have an easy sanity check at this point:
+does the host operating system see the JTAG adapter?
+
+@item @emph{Connect the adapter's power supply, if needed.}
+This step is primarily for non-USB adapters,
+but sometimes USB adapters need extra power.
+
+@item @emph{Power up the target board.}
+Unless you just let the magic smoke escape,
+you're now ready to set up the OpenOCD server
+so you can use JTAG to work with that board.
+
 @end enumerate
 
-@section Small configuration file method
+Talk with the OpenOCD server using
+telnet (@code{telnet localhost 4444} on many systems) or GDB.
+@xref{GDB and OpenOCD}.
 
-This is the preferred method. It is simple and works well for many
-people. The developers of OpenOCD would encourage you to use this
-method. If you create a new configuration please email new
-configurations to the development list.
+@section Project Directory
 
-Here is an example of an openocd.cfg file for an ATMEL at91sam7x256
+There are many ways you can configure OpenOCD and start it up.
 
+A simple way to organize them all involves keeping a
+single directory for your work with a given board.
+When you start OpenOCD from that directory,
+it searches there first for configuration files
+and for code you upload to the target board.
+It is also be the natural place to write files,
+such as log files and data you download from the board.
+
+@section Configuration Basics
+
+There are two basic ways of configuring OpenOCD, and
+a variety of ways you can mix them.
+Think of the difference as just being how you start the server:
+
+@itemize
+@item Many @option{-f file} or @option{-c command} options on the command line
+@item No options, but a @dfn{user config file}
+in the current directory named @file{openocd.cfg}
+@end itemize
+
+Here is an example @file{openocd.cfg} file for a setup
+using a Signalyzer FT2232-based JTAG adapter to talk to
+a board with an Atmel AT91SAM7X256 microcontroller:
+
 @example
 source [find interface/signalyzer.cfg]
 
@@ -751,68 +837,174 @@
 source [find target/sam7x256.cfg]
 @end example
 
-There are many example configuration scripts you can work with. You
-should look in the directory: @t{$(INSTALLDIR)/lib/openocd}. You
-should find:
+Here is the command line equivalent of that configuration:
 
+@example
+openocd -f interface/signalyzer.cfg \
+        -c "gdb_memory_map enable" \
+        -c "gdb_flash_program enable" \
+        -f target/sam7x256.cfg
+@end example
+
+You could wrap such long command lines in shell scripts,
+each supporting a different development task.
+One might re-flash the board with specific firmware version.
+Another might set up a particular debugging or run-time environment.
+
+Here we will focus on the simpler solution:  one user config
+file, including basic configuration plus any TCL procedures
+to simplify your work.
+
+@section User Config Files
+@cindex config file
+@cindex user config file
+
+A user configuration file ties together all the parts of a project
+in one place.
+One of the following will match your situation best:
+
+@itemize
+@item Ideally almost everything comes from configuration files
+provided by someone else.
+For example, OpenOCD distributes a @file{scripts} directory
+(probably in @file{/usr/share/openocd/scripts} on Linux);
+board and tool vendors can provide these too.
+The AT91SAM7X256 example above works this way.
+
+Three main types of non-user configuration file each have their
+own subdirectory in the @file{scripts} directory:
+
 @enumerate
-@item @b{board} - eval board level configurations
-@item @b{interface} - specific dongle configurations
-@item @b{target} - the target chips
-@item @b{tcl} - helper scripts 
-@item @b{xscale} - things specific to the xscale.
+@item @b{interface} -- one for each kind of JTAG adapter/dongle
+@item @b{board} -- one for each different board
+@item @b{target} -- the chips which integrate CPUs and other JTAG TAPs
 @end enumerate
 
-Look first in the ``boards'' area, then the ``targets'' area. Often a board
-configuration is a good example to work from.
+Best case:  include just two files, and they handle everything else.
+The first is an interface config file.
+The second is board-specific, and it sets up the JTAG TAPs and
+their GDB targets (by deferring to some @file{target.cfg} file),
+declares all flash memory, and leaves you nothing to do except
+meet your deadline:
 
-@section Many -f filename options
-Some believe this is a wonderful solution, others find it painful.
+@example
+source [find interface/olimex-jtag-tiny.cfg]
+source [find board/csb337.cfg]
+@end example
 
-You can use a series of ``-f filename'' options on the command line,
-OpenOCD will read each filename in sequence, for example:
+Boards with a single microcontroller often won't need more
+than the target config file, as in the AT91SAM7X256 example.
+That's because there is no external memory (flash, DDR RAM), and
+the board differences are encapsulated by application code.
 
+@item You can often reuse some standard config files but
+need to write a few new ones, probably a @file{board.cfg} file.
+You will be using commands described later in this User's Guide,
+and working with the guidelines in the next chapter.
+
+For example, there may be configuration files for your JTAG adapter
+and target chip, but you need a new board-specific config file
+giving access to your particular flash chips.
+Or you might need to write another target chip configuration file
+for a new chip built around the Cortex M3 core.
+
+@quotation Note
+When you write new configuration files, please submit
+them for inclusion in the next OpenOCD release.
+For example, a @file{board/newboard.cfg} file will help the
+next users of that board, and a @file{target/newcpu.cfg}
+will help support users of any board using that chip.
+@end quotation
+
+@item
+You may may need to write some C code.
+It may be as simple as a supporting a new new ft2232 or parport
+based dongle; a bit more involved, like a NAND or NOR flash
+controller driver; or a big piece of work like supporting
+a new chip architecture.
+@end itemize
+
+Reuse the existing config files when you can.
+Look first in the @file{scripts/boards} area, then @file{scripts/targets}.
+You may find a board configuration that's a good example to follow.
+
+When you write config files, separate the reusable parts
+(things every user of that interface, chip, or board needs)
+from ones specific to your environment and debugging approach.
+
+For example, a @code{gdb-attach} event handler that invokes
+the @command{reset init} command will interfere with debugging
+early boot code, which performs some of the same actions
+that the @code{reset-init} event handler does.
+Likewise, the @command{arm9tdmi vector_catch} command (or
+its @command{xscale vector_catch} sibling) can be a timesaver
+during some debug sessions, but don't make everyone use that either.
+Keep those kinds of debugging aids in your user config file.
+
+@section Project-Specific Utilities
+
+A few project-specific utility
+routines may well speed up your work.
+Write them, and keep them in your project's user config file.
+
+For example, if you are making a boot loader work on a
+board, it's nice to be able to debug the ``after it's
+loaded to RAM'' parts separately from the finicky early
+code which sets up the DDR RAM controller and clocks.
+A script like this one, or a more GDB-aware sibling,
+may help:
+
 @example

-Please try to ``source'' various files or use the multiple -f

-@section Advice for you
-Often, one uses a ``mixed approach''. Where possible, please try to
-``source'' common things, and if needed cut/paste parts of the
-standard distribution configuration files as needed.
+@example
+proc newboot @{ @} @{
+    # Reset, leaving the CPU halted.  The "reset-init" event
+    # proc gives faster access to the CPU and to NOR flash;
+    # "reset halt" would be slower.
+    reset init
 
-@b{REMEMBER:} The ``important parts'' of your configuration file are:
+    # Write standard version of U-Boot into the first two
+    # sectors of NOR flash ... the standard version should
+    # do the same lowlevel init as "reset-init".
+    flash protect 0 0 1 off
+    flash erase_sector 0 0 1
+    flash write_bank 0 u-boot.bin 0x0
+    flash protect 0 0 1 on

+    # Reboot from scratch using that new boot loader.

+@end example
 
-Some key things you should look at and understand are:
+You may need more complicated utility procedures when booting
+from NAND.
+That often involves an extra bootloader stage,
+running from on-chip SRAM to perform DDR RAM setup so it can load
+the main bootloader code (which won't fit into that SRAM).

Log:
David Brownell <da...@pa...>:

Update "arm9tdmi vector_catch" command description to highlight both
use cases (display configuration, or first change that config) and
to explain a bit more about what this is:  an alternative to using
hardware breakpoint resources.

Note that I tried this on an arm920t, but it didn't work.  Set bits,
then examined them and they weren't set.  And it didn't seem to act
as if vector triggering was noticed, either.

Also some minor unrelated tweaks:  @ignore some unused or don't-use
event names; fix a few typos; tweak chip-specific reset descriptions.
