* debug: use assert's when approperiateØyvind Harboe2010-08-112-4/+2
| | | | | | error was returned instead of using assert. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* arm: add missing error reportingØyvind Harboe2010-08-113-1/+28
| | | | | | | when an unknown core mode is read from the target, report error. Can be communication failure. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* arm7/9: fix "reset run + halt"Øyvind Harboe2010-08-092-11/+27
| | | | | | | | | | | | | | | | if polling is off, then "reset run + halt" would fail since halt incorrectly assumed the target was in the reset state as it is the internal poll implementation that moves the sw tracking of the target state out of the reset state. To reproduce: > reset run; halt JTAG tap: zy1000.cpu tap/device found: 0x1f0f0f0f (mfg: 0x787, part: 0xf0f0, ver: 0x1) BUG: arm7/9 does not support halt during reset. This is handled in arm7_9_assert_reset() Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* target: if polling fails, back offØyvind Harboe2010-08-091-8/+29
| | | | | | | | | | | | back-off algorithm for polling. Double polling interval up to 5000ms when it fails. when polling succeeds, reset backoff. This avoids flooding logs(as much) when working with conditions where the target polling will fail. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* verify_image: print out a statement that there are no further errorsØyvind Harboe2010-08-021-1/+10
| | | | | | | | | It is useful to know that the printed errors are *all* the errors there were. Added missing error handling(found by inspection). Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* zy1000: use correct base clock when calculating speed divisorØyvind Harboe2010-08-021-4/+11
| | | | | | revc uses 60MHz and revb 64MHz, use this in calculations. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* zy1000: print out khz correctly in response to setting JTAG speedØyvind Harboe2010-08-021-4/+33

* 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>
* util: ms command to calculate length of operationsØyvind Harboe2010-08-015-2/+101
| | | | | | | This can be used to calculate approximate RTCK frequency for instance. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* stellaris flash comment updateDavid Brownell2010-08-011-1/+1
| | | | | | | | This flash driver works on more than just two chips. (Though it does need work still, e.g. to protect more than 64K. (On non-'3748-A0 chips where errata allow that.)) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* "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>

* 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. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* 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?? Signed-off-by: David Brownell <db@helium.(none)>

| | | | | | | | | 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>
