SourceForge Upgrade

November 16th, 2012

We have upgraded OpenOCD to the new SourceForge platform(Allura), part of that change is a move in the git repo url.

original url is:
and this has changed to:

So you will either need to re-clone or manually update your .git/config
git config remote.origin.url git:// should do the trick

Hopefully nothing has broken in the update.

OpenOCD 0.6.1 bugfix release

October 7th, 2012

Today OpenOCD 0.6.1 bugfix release was published on project’s download area on SourceForge. Appropriate changes were also committed to GIT repository.

This release addresses serious regression in 0.6.0 and 0.6.0-rc2 releases which caused some functionalities to work correctly only on the first run – all following operations would fail until OpenOCD would be restarted. Some of affected modules:

  • lpc2000 flash driver (for LPC2xxx and LPC17xx chips),
  • mips_m4k fast data (for MIPS M4k chips),
  • feroceon DCC,
  • arm_io NAND flash driver,
  • arm7_9 DCC.

Last unaffected release (of course excluding 0.6.1) is 0.6.0-rc1. All users of affected releases are encouraged to update their version of OpenOCD.

Additionally this release includes following fixes:

  • fix of handling Hi-Z state in direct connections in new ftdi driver,
  • fix of handling RCLK in new ftdi driver,
  • improvements to config files using new ftdi driver,
  • fix for sector erase for AT91SAM4S chips,
  • fix of TAPID in STM32F3 config script,
  • support for STM32F3 Rev 2 flash,
  • support for STM32F3-DISCOVERY board.

As usual, Freddie Chopin has provided Window’s binaries on his site.
