* zy1000: embedded ice dcc tweakØyvind Harboe2010-03-081-21/+48
| | | | | | | | | | How many bits to shift out before/after enabled tap not in bypass is calculated outside the loop. This is more of a demonstration of principle and to clarify code than a performance optimisation as such. Follows up a bit on the simplification work in jtag interface.

* jtag: simplify jtag_add_plain_ir/dr_scanØyvind Harboe2010-03-086-64/+55
| | | | | | | These fn's now clearly just clock out/in bits. No mystical fields are involved. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* jtag: jtag_add_ir_scan() now takes a single fieldØyvind Harboe2010-03-087-26/+35
| | | | | | | | 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 Harboe2010-03-087-113/+52
| | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | The Redbee USB is a small form-factor usb stick from Redwire, LLC (www.redwirellc.com/store), built around a Freescale MC13224V ARM7TDMI + 802.15.4 radio (plus antenna). It includes an FT2232H for debugging, with Channel B connected to the mc13224v's JTAG interface (unusual) and Channel A connected to UART1.

| | | | | | | | | | | | | | | | | | | | | | | | | | The Redbee Econotag is an open hardware development kit from Redwire, LLC (www.redwirellc.com/store), for the Freescale MC13224V ARM7TDMI + 802.15.4 radio. It includes both an MC13224V and an FT2232H (for JTAG and UART support). It has flexible power supply options. Additional features are: - inverted-F pcb antenna - 36 GPIO brought out to 0.1" pin header (includes all peripheral pins) - Reset button - Two push buttons (on kbi1-5 and kbi0-4) - USB-A connector, powered from USB - up to 16V external input - pads for optional buck inductor - pads for optional 32.768kHz crystal - 2x LEDS on TX_ON and RX_ON [ dbrownell@users.sourceforge.net: shrink lines; texi ] Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ft2232: implement TMS sequence commandDavid Brownell2010-02-271-2/+72

* interface: define TMS sequence commandDavid Brownell2010-02-278-11/+124
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | zy1000 performance for GDB load went from 100kBytes/s to 300kBytes/s @ 8 MHz by implementing the inner loop of unack arm11 memory writes directly on top of the hw fifo.

| | | | | | | | | | | | | | | This allows minidrivers to e.g. hardware accelerate memory writes. Same trick as is used for arm7/9 dcc writes. Added error propagation for memory transfer failures in code rearrangement. Also the JTAG end state is not updated until after the memory write run is complete.

* 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>
