User mailing list

May 11th, 2012

To better help the user resolve issues with using OpenOCD, we have created a openocd-user mailing list. Hopefully with user input we can make OpenOCD a smoother experience for all.

For info other OpenOCD mailing lists can be found here.

Mailing Lists Working

January 3rd, 2012

All the mailing lists are back online now – all i can say is it took a lot longer than it should have (sf).

Mailing List Issues

November 29th, 2011

We are currently having issues with our mailing lists hosted on SF:

For some reason they have been deleted, SF are looking into it and hopefully we will be back online soon.

new helpers

November 8th, 2011

We have two new helpers to the OpenOCD team – Gerrit and Jenkins.

Gerrit is a web based review system that makes reviewing patches simpler for all – especially project devs.
Here is the link for our Gerrit server

Jenkins is a continuous integration server, and is being used to test any patches uploaded to Gerrit. This again makes our life simpler as some of the trivial tasks are now automated.
Here is the link for our Jenkins server.

The server has been kindly donated by the kind folks at Zylin.

In the long term this will hopefully mean a more stable OpenOCD.


mailing lists

November 8th, 2011

All mailing lists have now moved over to sourceforge, update any spam filters asap.
Users that were subscribed to the Berlios lists have been migrated over, so you should have nothing todo.


October 5th, 2011

Seems Berlios is closing on the 31/12/2011 :-(

This means the website (this) and the mailing lists will be moving to sourceforge – stay tuned for details.

OpenOCD v0.5.0 released

August 9th, 2011

It has been a while since an official OpenOCD release, but it is finally here !!

Many thanks to all that helped get this release out the door – in the future we are planning to release on a more regular schedule.

Here is the NEWS file relating to this release:

This file includes highlights of the changes made in the OpenOCD 0.5.0 source archive release.  See the repository history for details about what changed, including bugfixes and other issues not mentioned here.

JTAG Layer:

  • New driver for “Bus Pirate”
  • Rename various commands so they’re not JTAG-specific

There are migration procedures for most of these, but you should convert your scripts to the new names, since those procedures will not be around forever.
- jtag jinterface … is now adapter_name …
- jtag_khz … is now adapter_khz …
- jtag_nsrst_delay … is now adapter_nsrst_delay …
- jtag_nsrst_assert_width … is now adapter_nsrst_assert_width …

  • Support Voipac VPACLink JTAG Adapter.

Boundary Scan:

Transport framework core … supporting future work for SWD, SPI, and other non-JTAG ways to debug targets or program flash.

Target Layer:

  • ARM:
    - basic semihosting support for ARMv7M.
    - renamed “armv7m” command prefix as “arm”
  • MIPS:
    - “ejtag_srst” variant removed. The same functionality is obtained by using “reset_config none”.
    - added PIC32MX software reset support, this means srst is not required to be connected anymore.
  • OTHER:
    - preliminary AVR32 AP7000 support.

Flash Layer:

  • New “stellaris recover” command, implements the procedure to recover locked devices (restoring non-volatile state to the factory defaults, including erasing the flash and its protection bits, and possibly re-enabling hardware debugging).
  • PIC32MX now uses algorithm for flash programming, this has increased the performance by approx 96%.
  • New ‘pic32mx unlock’ cmd to remove readout protection.
  • New STM32 Value Line Support.
  • New ‘virtual’ flash driver, used to associate other addresses with a flash bank. See pic32mx.cfg for usage.
  • New iMX27 NAND flash controller driver.

Board, Target, and Interface Configuration Scripts:

  • Support IAR LPC1768 kickstart board (by Olimex)
  • Support Voipac PXA270/PXA270M module.
  • New $PARPORTADDR tcl variable used to change default parallel port address used.
  • Remove lm3s811.cfg; use “stellaris.cfg” instead

Core Jim/TCL Scripting:

  • New “add_script_search_dir” command, behaviour is the same as the “-s” cmd line option.
