* more careful luminary initDavid Brownell2010-07-191-7/+12
| | | | | | | | | | | Set up more of the Luminary-specific signals, and stop cloning a few of the JTAG defaults. More comments too. Still leaves the "dap info 0" bugs unresolved (presumably coupled to this particular adapter family) where TPIU, ITM, DWT, and other debug modules wrongly display as extra NVICs.

* transport selection tweaksDavid Brownell2010-07-091-11/+2
| | | | | | | | | | | | * Bugfix and simplify legacy jtag-only defaulting * Make "dummy" declare its jtag-only nature * likewise update ft2232 * warn if selection is _required_ (multi-transport adapters), fixes the "only ft2232 works" bug for at least dummy, with other drivers going the "legacy" path (submit patches).

* initial "transport" frameworkDavid Brownell2010-07-021-11/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the guts of a transport framework with initialization, which should work with current JTAG-only configurations (tested with FT2232). Each debug adapter can declare the transports it supports, and exactly one transport is initialized. (with its commands) in any given OpenOCD session. * Define a new "struct transport with init hooks and a few "transport" subcommands to support it: "list" ... list the transports configured (just "jtag" for now) "select" ... makes the debug session use that transport "init" ... initializes the selected transport (internal) * "interface_transports" ... declares transports the current interface can support. (Some will do this from C code instead, when there are no hardware versioning (or other) issues to prevent it. Plus some FT2232 tweaks, including a few to streamline upcoming support for an SWD transport (initially for Luminary adapters). Eventually src/jtag should probably become src/transport, moving jtag-specific stuff to transport/jtag. Signed-off-by: David Brownell <db@helium.(none)>

* ft2232 init mess cleanupDavid Brownell2010-03-211-60/+99
| | | | | | | | | | | | | | | | | | | | | | In the ft2232 driver, initialization for many layouts punts to a routine called usbjtag_init(), instead of a routine specific to each layout. That routine is a mess built around a "what type layout am I" core. That's a bad design ... in this case, especially so, since it bypasses the layout-specific dispatch which was just done, and obfuscates the initialization which is at least somewhat generic, instead of being specific to the "usbjtag" layout. Split and document out the generic parts of usbjtag_init(), and make the rest of those layouts have layout-specific init methods. Also, rename usbjtag_reset() ... that also was not specific to the "usbjtag" layout, and thus contributed to the previous code structure confusion. (Eventually, all layout-specific code (and method tables) should probably live in files specific to each layout. These changes will facilitate those and other cleanups to this driver.)

* FT2232: lookup and save layout just onceDavid Brownell2010-03-141-31/+39
| | | | | | | | | | | | | | Streamline use of the layout: have the "ft2232_layout" command look it up and save the result, instead of having a few different chunks of code looking it up later, and saving just its name (which is already part of the layout). This - is cleaner - reports errors sooner - facilitates earlier adapter-specific setup - removes unused "default to "usbjtag" logic Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* ft2232: add a mechanism to specify channel in layout structsMariano Alvira2010-02-251-3/+7
| | | | | | | | | | | | | | | | | | | | | | | FT2232-family chips have two or more MPSSE modules. FTDI documentation calls these channels. JTAG adapter drivers thus need to be able to choose which channel to use. (For example, one channel may connect to a board's microcontroller, while another connects to a CPLD.) Since each channel has its own USB interface, libftdi (somewhat confusingly) identifies channels using INTERFACE_* symbols. Most boards use INTERFACE_A for JTAG, which is the default in OpenOCD. But some wire up a different one. Note that there are two facets of what makes a wiring "layout": - The mapping between debug signals map and channel signals ... embedded in C functions. - Label used in Tcl configuration scripts ... part of the "layout" structure. By letting the channel be part of the layout struct, we permit sharing the C functions between Tcl-visible layouts, when those signal mappings are reused.

* ft2232 table init cleanupDavid Brownell2010-02-211-19/+78

* Fix Luminary FT2232 layout docs/configsDavid Brownell2009-12-281-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of this patch updates documentation and comments for various Luminary boards, supporting two bug fixes by helping to make sense of the current mess: - Recent rev C lm3s811 eval boards didn't work. They must use the ICDI layout, which sets up some signals that the older boards didn't need. This is actually safe and appropriate for *all* recent boards ... so just make "luminary.cfg" use the ICDI layout. - "luminary-lm3s811.cfg", was previously unusable! No VID/PID; and the wrong vendor string. Make it work, but reserve it for older boards where the ICDI layout is wrong. - Default the LM3748 eval board to "luminary.cfg", like the other boards. If someone uses an external JTAG adapter, all boards will use the same workaround (override that default). The difference between the two FT2232 layouts is that eventually the EVB layout will fail cleanly when asked to enable SWO trace, but the ICDI layout will as cleanly be able to enable it. Folk using "luminary.cfg" with Rev B boards won't see anything going wrong until SWO support is (someday) added. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
