Loading Linux on LM3S8962

Other Parts Discussed in Thread: LM3S8962

Hi

I have a Stellaris LM3S8962 ARM Eval Board. I am working on a embedded application to use LINUX on this board. Is it possible to load LINUX on this board? If so let me know the procedure for doing so.

Thanks & Regards

Sunil

    Is it possible to load LINUX on this board?

    In the broad sense you phrased your question - no, Linux won't run on your board. Linux requires an MMU, which Cortex-M3/M4 MCUs clearly lack.

    There are ucLinux ports to some M3/M4 chips. ucLinux is a downscaled variant for microcontrollers with few ressources, and without virtual addressing (MMU).

    I know of a port to the STM32F4, which takes about 2MB Flash, and uses the 196kB of RAM this MCU has. Expect similiar memory requirements - or less, if you scale down on features. According to my experiences, this disqualifies such a solution for any commercial project, as they tend to be rather price-sensitive.

    Not sure if any port to a LM3S exists, perhaps someone else on this list knows. But since the LM3 is about to be phased out, don't expect much support from TI in this regard. And BTW, TI has a good choice of inexpensive Linux-capable boards with larger Cortex-A processors.
