* jtag: measure_clk debug procØyvind Harboe2010-08-021-0/+9
| | | | | | | It can be useful to get an approximate measurement of rtck frequency for debugging purposes. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* jtag: add jtag_flush_queue_sleep debug commandØyvind Harboe2010-08-023-0/+45
| | | | | | | | it can be useful to throttle performance: test differences in behavior, test performance effect of long roundtrips. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* "transport select" returns Jim valueDavid Brownell2010-07-241-41/+30
| | | | | | | Make it scriptable, so code can be conditionalized based on what transport is in use for the session. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* 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.

* comments for Luminary ICDI layoutDavid Brownell2010-07-181-3/+27

* debug feature: jtagtcpip, improve performanceØyvind Harboe2010-07-162-0/+26
| | | | | | | | | waiting for ZY1000 fifo to idle is now queued as an asynchronous command. This radically improves performance when waitIdle() is interspersed with writes as no readback is required over TCP/IP. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* initial "transport" frameworkDavid Brownell2010-07-027-11/+571
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)>

* jtag/tcl.c cleanup -- split out "adapter.c"David Brownell2010-03-274-430/+466
| | | | | | | | | | | | Clean up the jtag/tcl.c file, which was one of the biggest and messiest ones in that directory. Do it by splitting out all the generic adapter commands to a separate "adapter.c" file (leaving the "tcl.c" file holding only JTAG utilities). Also rename the little-used "jtag interface" to "adapter_name", which should have been at least re-categorized earlier (it's not jtag-only).

* 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.)
