* add board/redbee-econotag.cfg and JTAG supportMariano Alvira2010-02-273-0/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Add target/mc13224v.cfgMariano Alvira2010-02-271-0/+54
| | | | | | | | | | | | | | | | | The MC13224V is a FreeScale ARM7TDMI based IEEE802.15.4 platform for Zigbee and similar low-power wireless applications. Using PIP (Platform In Package) technology, it integrates: an RF balun and matching network; a buck converter (only an external inductor is necessary); 96KB of SRAM; and 128KB of non-volatile memory. It has an integrated bootloader and can boot from a variety of sources: external SPI or I2C non-volatile memory, an image loaded over UART1, or the internal non-volatile memory. The image loaded from one of these sources is executed directly from SRAM starting at location 0x00400000.

* new "stellaris recover" commandDavid Brownell2010-02-273-0/+87
| | | | | | | | | | | | | | | Stellaris chips have a procedure for restoring the chip to what's effectively the "as-manufactured" state, with all the non-volatile memory erased. That includes all flash memory, plus things like the flash protection bits and various control words which can for example disable debugger access. clearly, this can be useful during development. Luminary/TI provides an MS-Windows utility to perform this procedure along with its Stellaris developer kits. Now OpenOCD users will no longer need to use that MS-Windows utility.

* ADIv5 DAP ops switching to JTAG or SWD modesDavid Brownell2010-02-272-0/+121
| | | | | | | | | | | Define two new DAP operations which use the new jtag_add_tms_seq() calls to put the DAP's transport into either SWD or JTAG mode, when the hardware allows. Tested with the Stellaris 'Recovering a "Locked" Device' procedure, which loops five times over both of these. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ft2232: implement TMS sequence commandDavid Brownell2010-02-271-2/+72
| | | | | | | Implement the new TMS_SEQ command on FT2232 hardware. Also, swap a bogus exit() call with a clean failure return. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* 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.

* ARM ADIv5: rename more JTAG-specific routinesDavid Brownell2010-02-231-11/+11
| | | | | | | Highlight more of the internal JTAG-specific utilities, so it's easier to identify code needing changes to become transport-neutral. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| | | | | | | | | | | | | | | | 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.

* arm11: allow minidrivers to implement inner loop of memory writesØyvind Harboe2010-02-222-45/+100
| | | | | | | | | | | | | | | 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.

* ft2232 table init cleanupDavid Brownell2010-02-211-19/+78
| | | | | | | | Use labeled initializers in the table of layouts instead of positional ones. This ls cleaner and less error prone, plus it simplifies patches which add members to these structure. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* ADIv5: relocate memacess_tck cyclesDavid Brownell2010-02-211-12/+12
| | | | | | | | | | | | | When using an AP to access a memory (or a memory-mapped register), some extra TCK (assuming JTAG) cycles should be added to ensure the AP has enugh time to complete that access before trying to collect the response. The previous code was adding these cycles *before* trying to access (read or write) data to that address, not *after*. Fix by putting the delays in the right location.

* ADIv5: remove ATOMIC/COMPOSITE interface modeDavid Brownell2010-02-213-98/+29
| | | | | | | | | | | | | This removes context-sensitivity from the programming interface and makes it possible to know what a block of code does without needing to know the previous history (specifically, the DAP's "trans_mode" setting). The mode was only set to ATOMIC briefly after DAP initialization, making this patch be primarily cleanup; almost everything depends on COMPOSITE. The transactions which shouldn't have been queued were already properly flushing the queue. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: ADIv5, deadcode cleanupDavid Brownell2010-02-211-13/+13
| | | | | | | | | | | | I have no idea what the scan_inout_check() was *expecting* to achieve by issuing a read of the DP_RDBUFF register. But in any case, that code was clearly never being called ("invalue" always NULL) ... so remove it, and the associated comment. Also rename it as ap_write_check(), facilitating a cleanup of its single call site by removing constant parameters. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: ADIv5 code shrinkage, cleanupDavid Brownell2010-02-211-40/+16
| | | | | | | | | | adi_jtag_dp_scan_u32() now wraps adi_jtag_dp_scan(), removing code duplication. Include doxygen for the former. Comment some particularly relevant points. Minor fault handling fixes for both routines: don't register a callback that can't run, or return ERROR_OK after an error. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ADIv5 clean up AP fault handlingDavid Brownell2010-02-211-32/+46
| | | | | | | | | | | | | | | | | Pass up fault codes from various routines, so their callers can clean up after failures, and remove the FIXME comments highlighting those previously goofy code paths. dap_ap_{read,write}_reg_u32() dap_ap_write_reg() mem_ap_{read,write}_u32() mem_ap_{read,write}_atomic_u32() dap_setup_accessport() Make dap_ap_write_reg_u32() just wrap dap_ap_write_reg(), instead of cloning its core code (and broken fault handling).

* ADIv5 clean up AP selection and register cachingDavid Brownell2010-02-214-34/+60
| | | | | | | | | | | | | | | | | | | Handling of AP (and AP register bank) selection, and cached AP registers, is pretty loose ... start tightening it: - It's "AP bank" select support ... there are no DP banks. Rename. + dap_dp_bankselect() becomes dap_ap_bankselect() + "dp_select_value" struct field becomes "ap_bank_value" - Remove duplicate AP cache init paths ... only use dap_ap_select(), and don't make Cortex (A8 or M3) cores roll their own code. - For dap_ap_bankselect(), pass up any fault code from writing the SELECT register. (Nothing yet checks those codes.) - Add various bits of Doxygen Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: keep a handle to the PCDavid Brownell2010-02-2116-88/+106
| | | | | | | | | | | | | | | | Keep a handle to the PC in "struct arm", and use it. This register is used a fair amount, so this is a net minor code shrink (other than some line length fixes), but mostly it's to make things more readable. For XScale, fix a dodgy sequence while stepping. It was initializing a variable to a non-NULL value, then updating it to handle the step-over-active-breakpoint case, and then later testing for non-NULL to see if it should reverse that step-over-active logic. It should have done like ARM7/ARM9 does: init to NULL. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM DPM: support adding/removing HW breakpointsDavid Brownell2010-02-211-38/+113
| | | | | | | | | | | | | | Generalize the core of watchpoint setup so that it can handle breakpoints too. Create breakpoint add/remove routines which will use that, and hook them up to target types which don't provide their own breakpoint support (nothing, yet). This suffices for hardware-only breakpoint support. The ARM11 code will be able to switch over to this without much trouble, since it doesn't yet handle software breakpoints. Switching Cortex-A8 will be a bit more involved. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: per-core options should not be globalDavid Brownell2010-02-212-33/+44
| | | | | | | | | | Address some FIXME comments by getting rid of globals, moving per-core parameters in the existing per-core data structure. This will matter most whenever there are multiple ARM11 cores, e.g. ARM11 MPcore chips, but in general is just cleanup. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARMv7-M: start using "struct arm"David Brownell2010-02-215-9/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | This sets up a few of the core "struct arm" data structures so they can be used with ARMv7-M cores. Specifically, it: - defines new ARM core_modes to match the microcontroller modes (e.g. HANDLER not IRQ, and two types of thread mode); - Establishes a new microcontroller "core_type", which can be used to make sure v7-M (and v6-M) cores are handled right; - adds "struct arm" to "struct armv7m" and arranges for the target_to_armv7m() converter to use it; - sets up the arm.core_cache and arm.cpsr values - makes the Cortex-M3 code maintain arm.map and arm.core_mode. This is currently set up as a parallel data structure, primarily to minimize special cases for the semihosting support with microcontroller profile cores. Later patches can rip out the duplicative ARMv7-M support and start reusing core ARM code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* arm920t line length cleanupDavid Brownell2010-02-201-115/+247
| | | | | | | | | | | | The recent patch to fixbreakpoints and dcache handling added a bunch of overlong lines (80+ chars) ... shrink them, and do the same to a few lines which were already overlong. Also add a few FIXME comments to nudge (a) replacement of some magic numbers with opcode macros, which will be much better at showing what's actually going on, and (b) correct return codes.

* atm920t : fix breakpoints and data cache handlingMarc Pignat2010-02-191-17/+103
| | | | | | | | | Breakpoints did not work because the data cache was not flushed properly. As a bonus add capability to write to memory marked as read only by the MMU, which allows software breakpoints in such memory regions.
* ARM920T scanchain 15 comments/cleanupDavid Brownell2010-02-161-51/+112
| | | | | | | | | | | | | | | | | For folk who don't know the ARM920 JTAG interface very well, the two modes of scan chain 15 access to CP15 are confusing. Make those parts of the ARM920 code less opaque, by: - Adding comments referencing the relevant parts of the TRM, catching up to similar updates in the User's Guide. - Replacing magic numbers in physical access clients with symbolic equivalents.
