-The OpenOCD 0.2.0 source archive release includes numerous improvements
-that were made since the initial 0.1.0 source archive release. Many
-contributors helped make this release a great success, and the community
-of developers and maintainers look forward to any response.
-
-In addition to the list of changes below, countless bug fixing and
-cleaning was performed across the tree. Various TCL command parameters
-must past stricter value checks, and many more error conditions have
-been handled correctly. These efforts helped to make the 0.2.0 release
-more stable and robust, though some changes may expose latent bugs in
-your existing configuration scripts.
-
-This release does not maintain backward compatibility in all respects,
-so some target or configuration scripts may need to be updated. In some
-cases, you may also see warnings; resolve those, because they indicate
-commands that will be removed in the future.
-
-The following areas of OpenOCD functionality changed in this release:
+This file includes highlights of the changes made in the
+OpenOCD 0.4.0 source archive release. See the repository
+history for details about what changed, including bugfixes
+and other issues not mentioned here.
JTAG Layer:
-- Improves modularity: core, TCL, driver commands, and interface have
- been separated, encapsulated, and documented for developers. Mostly.
-- Improves JTAG TAP transition tables:
- * Makes TAP paths variable length, rather than being fixed at 7 steps.
- * Fixes problems with some targets that did not like longer paths.
-- Improves JTAG driver/minidriver modularity and encapsulation.
-- New drivers:
- * Adds stub minidriver for developing new embedded JTAG interfaces.
-- Improves drivers:
- * ft2232+ftd2xx:
- + Adds initial high-speed device support: --enable-ftd2xx-highspeed
- + Supports more types of FTDI-based devices.
- * jlink:
- + Works with more versions of the firmware (v3 and newer)
- + Supports dynamically detects device capabilities and limits
- * vsllink:
- + Supports very long scan chains
- * amtjtagaccel:
- + Fixes broken ID code detection problems.
+ Support KT-Link JTAG adapter.
+Boundary Scan:
Target Layer:
-- New devices: AVR, FA526
-- Improved support: ARM ADI, ARM11, MIPS
-- Numerous other bug fixes and improvements
+ General
+ - new "reset-assert" event, for systems without SRST
+ ARM
+ - renamed "armv4_5" command prefix as "arm"
+ - recognize TrustZone "Secure Monitor" mode
+ - "arm regs" command output changed
+ - register names use "sp" not "r13"
+ - add top-level "mcr" and "mrc" commands, replacing
+ various core-specific operations
+ - basic semihosting support
+ ARM11
+ - Preliminary ETM and ETB hookup
+ - accelerated "flash erase_check"
+ - accelerated GDB memory checksum
+ - support "arm regs" command
+ - can access all core modes and registers
+ - watchpoint support
+ Cortex-A8
+ - support "arm regs" command
+ - can access all core modes and registers
+ - supports "reset-assert" event (used on OMAP3530)
+ - watchpoint support
+ Cortex-M3
+ - Exposed DWT registers like cycle counter
+ ETM, ETB
+ - "trigger_percent" command moved ETM --> ETB
+ - "etm trigger_debug" command added
Flash Layer:
-- Improved drivers: mflash
-- New drivers: AT91SAM3, AVR, Davinci NAND
+ 'flash bank' and 'nand device' take <bank_name> as first argument.
+ With this, flash/NAND commands allow referencing banks by name:
+ - <bank_name>: reference the bank with its defined name
+ - <driver_name>[.N]: reference the driver's Nth bank
+ New 'nand verify' command to check bank against an image file.
+ The "flash erase_address" command now rejects partial sectors;
+ previously it would silently erase extra data.
-Board, Interface, and Target Configuration Scripts:
-- Many new and improved targets and boards are now available.
-- Better separation of "board" and "target" configuration
-- Moved all TCL files to top-level "tcl" directory in the source tree
-- Installation moved from '$pkglibdir/' to '$pkgdatadir/scripts/'.
-- Site-specific files should be installed under '$pkgdatadir/site/';
- files that exist this tree will be used in preference to default
- distribution configurations in '$pkgdatadir/scripts/'.
+Board, Target, and Interface Configuration Scripts:
+ ARM9
+ - ETM and ETB hookup for iMX2* targets
+ Add $HOME/.openocd to the search path.
+
+Core Jim/TCL Scripting:
+ New 'usage' command to provide terse command help.
+ Improved command 'help' command output (sorted and indented).
+ Improved command handling:
+ - Most boolean settings now accept any of the following:
+ on/off, enable/disable, true/false, yes/no, 1/0
+ - More error checking and reporting.
Documentation:
-- Updated User Guide: http://openocd.berlios.de/doc/html/index.html
- * Partially re-written and re-organized.
- * Standardized presentation for all commands.
- * Covers many drivers and commands that were previously omitted.
- * New index for commands and drivers.
-- Added Developer Manual: http://openocd.berlios.de/doc/doxygen/index.html
- * Now includes architecture, technical primers, style guides, and more.
- * Available in-tree and on-line.
+ New built-in command development documentation and primer.
Build and Release:
-- Increased configuration and compilation warning coverage.
- * Use --disable-werror to work around build errors caused by warnings.
-- Use libtool to produce helper libraries as a step toward "libopenocd".
-- New processes and scripting to facilitate future source releases.
+ Use --enable-doxygen-pdf to build PDF developer documentation.
+ Consider upgrading to libftdi 0.17 if you use that library; it
+ includes bugfixes which improve FT2232H support.
