* flash: remove algorithm exit_point address for supported targetsSpencer Oliver2010-07-204-5/+4
| | | | | | | | | For the above targets the exit_point is optional when used with run_algorithm, so remove it. This makes updating the algorithm less error prone. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* mips32: exit_point optional for mips32_run_algorithmSpencer Oliver2010-07-201-1/+1
| | | | | | | | | As the mips32 uses instruction breakpoints for algorithms we do not really need to check the pc on exit. This now matches the behaviour of the arm codebase. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* armv7m: exit_point optional for armv7m_run_algorithmSpencer Oliver2010-07-201-1/+1
| | | | | | | | | As the armv7m uses instruction breakpoints for algorithms we do not really need to check the pc on exit. This now matches the behaviour of the arm4_5 codebase. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* armv4_5: add algorithms instruction breakpoint supportSpencer Oliver2010-07-201-6/+16
| | | | | | | Update the arm_checksum_memory and arm_blank_check_memory algorithms to use a breakpoint instruction on v5 arch. Signed-off-by: Spencer Oliver <ntfreak@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.

* flash: add nuc910 nand driverSpencer Oliver2010-07-194-2/+306
| | | | | | | | This adds a nand driver support for the nuc910 target. Note that ECC is not currently supported by this driver, although it is supported by the peripheral. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>

* ARM ADI-V5: cleanup CID/PID addressingDavid Brownell2010-07-161-21/+23
| | | | | | | | | | | Use addition for offsetting, not masking. Shorten some lines. Make "component_start" print-only (unused otherwise; don't save). Still doesn't resolve the issue where multiple components are wrongly displaying as NVICs on some Cortex-M3 parts because many PIDs appear to be zeroes ... maybe adapter related??

* flash: use bkpt for str9 flash algo algorithmSpencer Oliver2010-07-161-3/+2

| | | | | | | | | 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>

* transport: fix segfault in setup_command_handler()Stacey Sheldon2010-07-051-0/+1
| | | | | | | | Commit 93f2afa45f4c dropped the sentinel off the end of the command_registrants[] array. The loop immediately following the initialization will walk right off the end. Signed-off-by: Stacey Sheldon <stac@solidgoldbomb.org>
* initial "transport" frameworkDavid Brownell2010-07-028-29/+587
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)>
