Energy Micro and Pengutronix announced that they will be demonstrating µClinux for Cortex-M3 on the EFM32 Gecko range (Leopard and Giant) of MCU during Embedded World Conference 2012 on 28 February – 1 March 2011 in Nuremberg, Germany.
Pengutronix’s port of µClinux features the Linux 3.2 kernel, providing the cost and time-to-market benefits of Linux operating system, while maintaining low current consumption of just 1.6mA when in idle mode.
The company explains that using µClinux reduces design cycles and accelerates time-to-market by giving the designer access to ready-made system functions such as IP connectivity, file systems, and multi-tasking. Users can also employ the broad range of free software and drivers available as open source, within a robust, portable open source framework.
The teaser video (below) shows that the demo platform (Giant Gecko Development Kit?) uses 4 MB of RAM (755 KB used after boot-up) and the MCU delivers 9.07 Bogomips. Energy Micro’s energyAware profiler will also be provided in order to profile the energy usage of your system and/or application.
Robert Schwebel, CEO of Pengutronix, will demo the platform during his presentation “Ultra Low Power: Applications with Giant Gecko and Cortex-M3” at 11:30 on Feb 1 of the Embedded World Conference 2012.
Neither companies provided further information for the time being. However, Pengutronix has previously released Embedded Linux BSPs for different target boards on http://www.pengutronix.de/oselas/bsp/index_en.html, so the Energy Micro Geckos port may be available there later on.

Finally , you could also read Linux for Cortex M3 & M4 Microcontrollers for other software/hardware solutions for uClinux on Cortex-M processors.
