Examples' update

After year and a half of silence I've finally decided to update example project for ARM core microcontrollers a bit. I have absolutely no idea why I waited for so long... Since last update some details of Eclipse configuration changed, so an update was definitely recommended (;

On this occasion a new example for STM32 Connectivity Line devices - STM32F105xSTM32F107x joins the group. Because the clock system in this devices is way more advanced (not to say "strange") than in "normal" STM32s, the function which calculates four parameters (two dividers and two multipliers) for two PLLs is a bit... longish (; However it does set highest achievable frequency with given quartz crystal resonator.

Main changes are configuration updates for new versions of OpenOCD (0.5.0), Eclipse (Indigo SR1) and GDB Hardware Debugging plugin (7.0.0.201109151620). In STM32 projects I've added function to configure GPIO pins mode. There are not many "visible" changes, that's why the version changes only from 1.2.0 to 1.2.1.

Example projects enjoy unflagging popularity, the most popular one - stm32_blink_led - was downloaded almost 5000 times! You can download updated versions from Download > ARM > Examples.

OpenOCD 0.5.0 finally published!

Almost one and a half year passed since last stable OpenOCD release... During this time 0.4.0 Windows installer was downloaded from this website over 16000 times and packages with development versions from this period - over 5000 times.

This time Windows version of the application was published - just as development versions - as a compressed .zip archive, not as .msi installer - I hope this won't be a problem for you, it's easier and faster to create such package instead of playing with installers (; . In Download > Software > OpenOCD you can download 32- and 64-bit version. Extract anywhere and you are ready to go (;

You can find highlights of major changes in NEWS file associated with this release in OpenOCD repository. There are not many of them, because this release should be treated as a stable update, without any revolutionary changes.

What next? The most anticipated feature - SWD (Serial Wire Debug) interface support, two-wire interface used in most recent Cortex chips - is in advanced stage. While you could use both "classic" JTAG and "modern" SWD in "bigger" chips like STM32 or LPC17xx, the smallest chips - like LPC11xx - can be debugged only via SWD. You can find more details on OpenOCD mailing list. Let's hope that test versions will be available soon! Stay tuned!

New development version of OpenOCD available at last!

I admit - lately I've neglected development versions of OpenOCD "a little", and when I finally got to it I've messed up my compilation environment... Then - just after setting up new one - I've managed to mess it up again (; Next - new compiler (GCC 4.7.0) threw like a million warnings (-Werror so errors) about unused variables at me, so it had to be fixed and patches had to be accepted. But this short story - just like many others - has a happy ending... After over 7 months - in Download > Software > OpenOCD dev new version is available for download, testing and using. Enjoy!
