  1. This file includes highlights of the changes made in the
  2. OpenOCD 0.4.0 source archive release. See the repository
  3. history for details about what changed, including bugfixes
  4. and other issues not mentioned here.
  5. JTAG Layer:
  6. Support KT-Link JTAG adapter.
  7. Support USB-JTAG, Altera USB-Blaster and compatibles.
  8. Boundary Scan:
  9. Target Layer:
  10. General
  11. - Removed commands which have been obsolete for at least
  12. a year (from both documentation and, sometimes, code).
  13. - new "reset-assert" event, for systems without SRST
  14. ARM
  15. - supports "reset-assert" event (except on Cortex-M3)
  16. - renamed "armv4_5" command prefix as "arm"
  17. - recognize TrustZone "Secure Monitor" mode
  18. - "arm regs" command output changed
  19. - register names use "sp" not "r13"
  20. - add top-level "mcr" and "mrc" commands, replacing
  21. various core-specific operations
  22. - basic semihosting support (ARM7/ARM9 only, for now)
  23. ARM11
  24. - Should act much more like other ARM cores:
  25. * Preliminary ETM and ETB hookup
  26. * accelerated "flash erase_check"
  27. * accelerated GDB memory checksum
  28. * support "arm regs" command
  29. * can access all core modes and registers
  30. * watchpoint support
  31. - Shares some core debug code with Cortex-A8
  32. Cortex-A8
  33. - Should act much more like other ARM cores:
  34. * support "arm regs" command
  35. * can access all core modes and registers
  36. * watchpoint support
  37. - Shares some core debug code with ARM11
  38. Cortex-M3
  39. - Exposed DWT registers like cycle counter
  40. - vector_catch settings not clobbered by resets
  41. - no longer interferes with firmware's fault handling
  42. ETM, ETB
  43. - "trigger_percent" command moved ETM --> ETB
  44. - "etm trigger_debug" command added
  45. MIPS
  46. - use fastdata writes
  47. Freescale DSP563xx cores (partial support)
  48. Flash Layer:
  49. 'flash bank' and 'nand device' take <bank_name> as first argument.
  50. With this, flash/NAND commands allow referencing banks by name:
  51. - <bank_name>: reference the bank with its defined name
  52. - <driver_name>[.N]: reference the driver's Nth bank
  53. New 'nand verify' command to check bank against an image file.
  54. The "flash erase_address" command now rejects partial sectors;
  55. previously it would silently erase extra data. If you
  56. want to erase the rest of the first and/or last sectors
  57. instead of failing, you must pass an explicit "pad" flag.
  58. New at91sam9 NAND controller driver.
  59. New s3c64xx NAND controller driver.
  60. Board, Target, and Interface Configuration Scripts:
  61. ARM9
  62. - ETM and ETB hookup for iMX2* targets
  63. Add $HOME/.openocd to the search path.
  64. Handle Rev C of LM3S811 eval boards.
  65. - use "luminary-lm3s811.cfg" for older boards
  66. - use "luminary.cfg" for RevC and newer
  67. Core Jim/TCL Scripting:
  68. New 'usage' command to provide terse command help.
  69. Improved command 'help' command output (sorted and indented).
  70. Improved command handling:
  71. - Most boolean settings now accept any of the following:
  72. on/off, enable/disable, true/false, yes/no, 1/0
  73. - More error checking and reporting.
  74. Documentation:
  75. New built-in command development documentation and primer.
  76. Build and Release:
  77. Use --enable-doxygen-pdf to build PDF developer documentation.
  78. Consider upgrading to libftdi 0.17 if you use that library; it
  79. includes bugfixes which improve FT2232H support.
  80. For more details about what has changed since the last release,
  81. see the git repository history. With gitweb, you can browse that
  82. in various levels of detail.
  83. For older NEWS, see the NEWS files associated with each release
  84. (i.e. NEWS-<version>).
  85. For more information about contributing test reports, bug fixes, or new
  86. features and device support, please read the new Developer Manual (or
  87. the BUGS and PATCHES.txt files in the source archive).
