Mailing list moved to Google Groups

I’ve created a group for distortos in Google Groups, with a plan to shut down the mailing list hosted on Sourceforge. The move is caused by the fact that Sourceforge is a dying service, which basically just waits for someone to pull the plug… Additionally Google Groups offers some nice features, most important one is that it is a mix of a regular mailing list and a forum. You can use it with your e-mail client only as well as solely via web browser. The new group is also available as an embedded page of this website, accessible with the Forum link from the main menu on the left.

It may be important to note, that you do NOT need a Gmail account to use this group. You can subscribe with any e-mail address you like.

I plan to keep the Sourceforge mailing list around for a while, but eventually it will be closed.

New tutorial about ARM debugging in Eclipse

Planned for very long, the tutorial about debugging a distortos-based project for ARM microcontroller in Eclipse was finally published – Documentation > Eclipse debugging setup for ARM microcontrollers. Even though the screenshots in the article were made on Windows 10, the guide is completely system-agnostic – the procedure will be identical on Linux.

This final guide completes the basic series of tutorials:

  1. ARM toolchain for Windows (Windows specific),
  2. Creating and configuring a project in Eclipse (mostly system-agnostic),
  3. Eclipse debugging setup for ARM microcontrollers (mostly system-agnostic).

Updated build instructions for kconfig-frontends

With the most recent gperf release – 3.1, released on 5th January 2017 (almost 8 years after previous 3.0.4) – the “standard” kconfig-frontends build procedure no longer works. The type of length argument used in generated functions was changed from unsigned int to size_t, which causes the build to fail with following error:

  CC     libkconfig_parser_la-yconf.lo
In file included from yconf.c:234:0:
hconf.gperf:141:1: error: conflicting types for 'kconf_id_lookup'
hconf.gperf:12:31: note: previous declaration of 'kconf_id_lookup' was here

Support for ARMv6-M architecture & STM32F0 chips

In the last few weeks distortos gained support for ARMv6-M architecture (ARM Cortex-M0(+) and ARM Cortex-M1 cores). The first chip family added to distortos using this architecture is STM32F0. You can select any of 72 chips from that family in the Kconfig configuration system and they are all supported by source code of distortos. Total number of supported chips rose to 281! Continue reading Support for ARMv6-M architecture & STM32F0 chips
