Weather during May's first weekend was truly disappointing, fortunately new software versions are "blooming" (;

On Friday, 3rd of May 2013, ~3 months after previous release, I have published the most recent compilation of the bleeding-edge-toolchain, tagged as 130503. Of the most interesting additions, configure options for newlib are worth mentioning, some of them very fresh: --disable-newlib-fvwrite-in-streamio, --disable-newlib-fseek-optimization and --disable-newlib-wide-orient. These options reduce code size of programs using stdio.h's functions. Additionally - thanks to removal of --enable-newlib-register-fini - if the program does not use functions like atexit() then support for that functionality will not be linked. Due to transfer limits of this website all bleeding-edge-toolchain files were moved to sourceforge website, in Download > Software > bleeding-edge-toolchain you will find links to appropriate locations.

And today, on 5th of May 2013, OpenOCD 0.7.0 was released. Since release of previous 0.6.1 version almost 7 months have passed and the Windows package was downloaded over 11000 times. There are not a lot of new things, but worth mentioning are: support for Texas Instruments' ICDI debugger, improved MIPS handling, support for Cortex-R4 (ARMv7R) architecture, support for ChibiOS/RT debugging, support for LPC43xx and LPC18xx (for chips with internal flash and with external memory connected via SPIFI interface), EFM32, STM32W and i.MX6. Package with Windows binaries is - as usually - available in Download > Software > OpenOCD.

Download and enjoy!

Additionally - "thanks" to monotony caused by constant rainfall - I have decided to start a facebook page for my company DISTORTEC, so I invite you to take a look and "Like!" it > https://www.facebook.com/Distortec

UPDATE 11.05.2013:

There is another version of bleeding-edge-toolchain available, tagged as 130509. There were exactly two reasons for this compilation. First one - it turns out that there is no --disable-newlib-atexit-alloc option, it should be --disable-newlib-atexit-dynamic-alloc - thanks to this option functions related to atexit() don't allocate memory dynamically. Second reason is related to the project I'm currently doing, which requires printf() / scanf() specifiers introduced in C99, like all those strange %hhx and so on. This second change causes a slight increase in RAM requirements of these functions - about ~80 bytes - you know, nothing is for free (; .
