PORT for ARM Cortex M3

raghu.ponuganti · Post by **raghu.ponuganti** » Tue Dec 25, 2012 6:23 pm

Hello,
I am a student of Embedded Systems Course from Darmstadt University of Applied Sciences.
As a part of my course I study OSEK and use it on a simulator. But to have practical exposure, I would like to use OSEK RTOS on ARM Cortex M3 controller (from ST, STM32 discovery board).
Is there a pre-configured OS Port available for ARM Cortex M3 ?
If not what is the best way to start with porting ?
Is there an easy way for porting to Cortex M3 ?

Thanks and regards
Raghavendra

Dear Raghavendra,

at this time there is support for cortex M0 and M4. You can find more details about that at
http://erika.tuxfamily.org/wiki/index.p ... _Cortex_MX.

I do not know the diference between M0, M4 and M3. Probably to port Erika to the Cortex M3, you can start from the most similar (M4? M0?) and follow steps explaned at http://erika.tuxfamily.org/wiki/index.p ... controller.

Note that recently Erika pass OSEK certification on Cortex M4 (http://www.evidence.eu.com/download/new ... ficate.pdf). Then, Cortex M4 is a good example for start a porting.

Best Regards,
Nicola

Hi!

Please also note that we support the STM32F4Discovery board... if you did not buy it yet then it could be much simpler as the porting is already available...

Ciao,

Hello Both,

Thank you very much for your support.
I am also new to Cortex microcontrollers, so mean while I started working with AVR port, am bit familiar with AVR. Once I succeed with using it on AVR I will proceed with Cortex.

I already have M3 discovery board but I can manage to get an M4 discovery board as well. So I will start with M4 and then will port it to M3. I want to try the OS porting :) .

Hope with your support I will succeed in porting.
Thank you once again.

regards

Hi!

Thanks for the message...

please note we published a set of porting examples on the wiki (http://erika.tuxfamily.org/wiki/index.p ... controller) ... that typically helps a lot when making a porting...

Have a Happy New Year,

PJ
