* 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.)

* rename jtag_khz as adapter_khzDavid Brownell2010-03-151-2/+2
| | | | | | | | | | | Globally rename "jtag_khz" as "adapter_khz", and move it out of the "jtag" command group ... it needs to be used with non-JTAG transports Includes a migration aid (in jtag/startup.tcl) so that old user scripts won't break.

* 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>

| | | | | | | | | | This patch greatly simplifies the Versaloon driver: - reducing the code size from more than 50K to less than 28K - adding support for IR/DR scan with unlimited size - using tap_get_tms_path and tap_get_tms_path_len. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* jtag: jtag_add_ir_scan() now takes a single fieldØyvind Harboe2010-03-081-3/+2
| | | | | | | | In the code a single field was all that was ever used. Makes jtag_add_ir_scan() simpler and leaves more complicated stuff to jtag_add_plain_ir_scan(). Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* jtag: retire tap fieldØyvind Harboe2010-03-081-27/+7
| | | | | | | | | | | | | | | | | jtag_add_dr/ir_scan() now takes the tap as the first argument, rather than for each of the fields passed in. The code never exercised the path where there was more than one tap being scanned, who knows if it even worked. This simplifies the implementation and reduces clutter in the calling code. use jtag_add_ir/dr_plain_scan() for more fancy situations. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* interface: define TMS sequence commandDavid Brownell2010-02-271-0/+25
| | | | | | | | | | | | | | | | | | | | | | | For support of SWD we need to be able to clock out special bit sequences over TMS or SWDIO. Create this as a generic operation, not yet called by anything, which is split as usual into: - upper level abstraction ... here, jtag_add_tms_seq(); - midlayer implementation logic hooking that to the lowlevel code; - lowlevel minidriver operation ... here, interface_add_tms_seq(); - message type for request queue, here JTAG_TMS. This is done slightly differently than other operations: there's a flag saying whether the interface driver supports this request. (In fact a flag *word* so upper layers can learn about other capabilities too ... for example, supporting SWD operations.) That approach (flag) lets this method *eventually* be used to eliminate pathmove() and statemove() support from most adapter drivers, by moving all that logic into the mid-layer and increasing uniformity between the various drivers. (Which will in turn reduce subtle bugginess.) 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.

* read target voltage first in vsllinksimon qian2010-01-171-0/+8
| | | | | | | | | | | | The very first command after init command should be "read target voltage". This is a tweak for the Old Versaloon firmware. Without this, in most most cases, it works. Under Ubuntu9.04, there is a chance that the USB will fail. The problem disappears if I read target voltage first. For the lastest Versaloon firmware, it's OK.

* 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>
