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:
Support KT-Link JTAG adapter.
Support USB-JTAG, Altera USB-Blaster and compatibles.
Boundary Scan:
Target Layer:
General
- new "reset-assert" event, for systems without SRST
ARM
- supports "reset-assert" event (except on Cortex-M3)
- 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 (ARM7/ARM9 only, for now)
ARM11
- Should act much more like other ARM cores:
* 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
- Shares some core debug code with Cortex-A8
Cortex-A8
- Should act much more like other ARM cores:
* support "arm regs" command
* can access all core modes and registers
* watchpoint support
- Shares some core debug code with ARM11
Cortex-M3
- Exposed DWT registers like cycle counter
- vector_catch settings not clobbered by resets
- no longer interferes with firmware's fault handling
ETM, ETB
- "trigger_percent" command moved ETM --> ETB
- "etm trigger_debug" command added
MIPS
- use fastdata writes
Freescale DSP563xx cores (partial support)
Flash Layer:
'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. If you
want to erase the rest of the first and/or last sectors
instead of failing, you must pass an explicit "pad" flag.
New at91sam9 NAND controller driver.
New s3c64xx NAND controller driver.
Board, Target, and Interface Configuration Scripts:
ARM9
- ETM and ETB hookup for iMX2* targets
Add $HOME/.openocd to the search path.
Handle Rev C of LM3S811 eval boards.
- use "luminary-lm3s811.cfg" for older boards
- use "luminary.cfg" for RevC and newer
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:
New built-in command development documentation and primer.
Build and Release:
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.
For more details about what has changed since the last release,
see the git repository history. With gitweb, you can browse that
in various levels of detail.
For older NEWS, see the NEWS files associated with each release
(i.e. NEWS-<version>).
For more information about contributing test reports, bug fixes, or new
features and device support, please read the new Developer Manual (or
the BUGS and PATCHES.txt files in the source archive).
