   9
  10 Boundary Scan:
  11
  12 Target Layer:
  13         General
  14                 - Removed commands which have been obsolete for at least
  15                   a year (from both documentation and, sometimes, code).
  16                 - new "reset-assert" event, for systems without SRST
  17         ARM
  18                 - supports "reset-assert" event (except on Cortex-M3)
  19                 - renamed "armv4_5" command prefix as "arm"
  20                 - recognize TrustZone "Secure Monitor" mode
  21                 - "arm regs" command output changed
  22                 - register names use "sp" not "r13"
  23                 - add top-level "mcr" and "mrc" commands, replacing
  24                   various core-specific operations
  25                 - basic semihosting support (ARM7/ARM9 only, for now)
  26         ARM11
  27                 - Should act much more like other ARM cores:
  28                    * Preliminary ETM and ETB hookup
  29                    * accelerated "flash erase_check"
  30                    * accelerated GDB memory checksum
  31                    * support "arm regs" command
  32                    * can access all core modes and registers
  33                    * watchpoint support
  34                 - Shares some core debug code with Cortex-A8
  35         Cortex-A8
  36                 - Should act much more like other ARM cores:
  37                    * support "arm regs" command
  38                    * can access all core modes and registers
  39                    * watchpoint support
  40                 - Shares some core debug code with ARM11
  41         Cortex-M3
  42                 - Exposed DWT registers like cycle counter
  43                 - vector_catch settings not clobbered by resets
  44                 - no longer interferes with firmware's fault handling
  45         ETM, ETB
  46                 - "trigger_percent" command moved ETM --> ETB
  47                 - "etm trigger_debug" command added
  48         MIPS
  49                 - use fastdata writes
  50         Freescale DSP563xx cores (partial support)
  51
  52 Flash Layer:
  53         'flash bank' and 'nand device' take <bank_name> as first argument.
  54         With this, flash/NAND commands allow referencing banks by name:
  55                 - <bank_name>: reference the bank with its defined name
  56                 - <driver_name>[.N]: reference the driver's Nth bank
  57         New 'nand verify' command to check bank against an image file.
  58         The "flash erase_address" command now rejects partial sectors;
  59                 previously it would silently erase extra data.  If you
  60                 want to erase the rest of the first and/or last sectors
  61                 instead of failing, you must pass an explicit "pad" flag.
  62         New at91sam9 NAND controller driver.
  63         New s3c64xx NAND controller driver.
  64
  65 Board, Target, and Interface Configuration Scripts:
  66         ARM9
  67                 - ETM and ETB hookup for iMX2* targets
  68         Add $HOME/.openocd to the search path.
  69         Handle Rev C of LM3S811 eval boards.
  70                 - use "luminary-lm3s811.cfg" for older boards
  71                 - use "luminary.cfg" for RevC and newer
  72
  73 Core Jim/TCL Scripting:
  74         New 'usage' command to provide terse command help.
  75         Improved command 'help' command output (sorted and indented).
  76         Improved command handling:
  77                 - Most boolean settings now accept any of the following:
  78                   on/off, enable/disable, true/false, yes/no, 1/0
  79                 - More error checking and reporting.

  81 Documentation:
  82         New built-in command development documentation and primer.
  83
  84 Build and Release:
  85         Use --enable-doxygen-pdf to build PDF developer documentation.
  86         Consider upgrading to libftdi 0.17 if you use that library; it
  87                 includes bugfixes which improve FT2232H support.
