In conjunction with manual register setup, this lets the ETM trigger cause entry to debug state. It should make it easier to test and bugfix the ETM code, by enabling non-trace usage and isolating bugs specific to thef ETM support. (One current issue being that trace data collection using the ETB doesn't yet behave.) For example, many ARM9 cores with an ETM should be able to implement four more (simple) breakpoints and two more (simple) watchpoints than the EmbeddedICE supports. Or, they should be able to support complex breakpoints, incorporating ETM sequencer, counters, and/or subroutine entry/exit criteria int criteria used to trigger debug entry.

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.
|
|
|
|
Boundary Scan:
|
|
Target Layer:
|
|
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:
|
|
'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:
|
|
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:
|
|
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.
