FreeRTOS and Stellaris LM4F

Alex Marcoux

I'm trying to figure out if the FreeRTOS supports the LM4F device. It is not clear and I don't see direct evidence it is.

Any help would be helpful.

Hi Alex,

My understanding is that floating point is not yet supported by FreeRTOS. However, Cortex M3 code can be run on a Cortex M4 without modification, so you should be able to use it, you just won't be able to take advantage of the floating point.

Regards,

Sue

How about FreeRtos source code could support floating point function, and could support LM4F now?

Hi Hanson,

You can download the current version of FreeRTOS, version 7.2.0 from http://www.freertos.org/RTOS.html. It supports the Cortex M4F.
