+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:
- FT2232H (high speed USB) support doesn't need separate configuration
- New FT2232H JTAG adapters: Amontec, Olimex, Signalyzer
- New reset_config options for SRST gating the JTAG clock (or not)
- TAP declaration no longer requires ircapture and mask attributes
- Scan chain setup should be more robust, with better diagnostics
- New TAP events:
- "post-reset" for TAP-invariant setup code (TAPs not usable yet)
- "setup" for use once TAPs are addressable (e.g. with ICEpick)
- Overridable Tcl "init_reset" and "jtag_init" procedures
- Simple "autoprobe" mechanism to help simplify server setup
+ Support KT-Link JTAG adapter.
Boundary Scan:
- SVF bugfixes ... parsing fixes, better STATE switch conformance
- XSVF bugfixes ... be more correct, handle Xilinx tool output
-
Target Layer:
- Warn on use of obsolete numeric target IDs
- New commands for use with Cortex-M3 processors:
- "cortex_m3 disassemble" ... Thumb2 disassembly (UAL format)
- "cortex_m3 vector_catch" ... traps certain hardware faults
- without tying up breakpoint resources
- If you're willing to help debug it
- VERY EARLY Cortex-A8 and ARMv7A support
- Updated BeagleBoard.org hardware support
- you may need to explicitly "reset" after connect-to-Beagle
- New commands for use with XScale processors: "xscale vector_table"
- ARM
- bugfixes to single-stepping Thumb code
- ETM: unavailable registers are not listed
- ETB, ETM: report actual hardware status
- ARM9
- name change: "arm9 vector_catch" not "arm9tdmi vector_catch"
- ARM11
- single stepping support for i.MX31
- bugfix for missing "arm11" prefix on "arm11 memwrite ..."
- GDB support
- gdb_attach command is gone
+ 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:
- The lpc2000 driver handles the new NXP LPC1700 (Cortex-M3) chips
- New drivers:
- lpc2900, for NXP LPC2900 chips (ARM968 based)
- mx3_nand, for imx31
- New "last" flag for NOR "flash erase_sector" and "flash protect"
- The "nand erase N" command now erases all of bank N
- Speed up davinci_nand by about 3x
+ '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, Target, and Interface Configuration Scripts:
- Amontec JTAGkey2 support
- Cleanup and additions for the TI/Luminary Stellaris scripts
- LPC1768 target (and flash) support
- Keil MCB1700 eval board
- Samsung s3c2450
- Mini2440 board
- Numeric TAP and Target identifiers now trigger warnings
- PXA255 partially enumerates
+ 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:
- Capture more debugging and setup advice
- Notes on target source code changes that may help debugging
+ New built-in command development documentation and primer.
Build and Release:
- Clean builds on (32-bit) Cygwin
- Clean builds on 64-bit MinGW
+ 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.
