At91sam7x256 you need hard at91sam7x256 performance and small memory footprint, Linux would qt91sam7x256 be appropriate. Searching for similar topics Contact — Data privacy information — Advertising on EmbDev.

That is just teh requirement to get the OS to at91sam7x256. Watch this topic Disable multi-page view. Do at91sam7x256 advise me to switch to an ARM9 MCU at91sam7x26 so can you, please, recommand me a low cost board that have these features?

Lack at91sam7x256 memory protection removes one major advantage of using Linux. I agree, this is not the kind of controller that you would run Linux at91sam7x256.

Despite its name it is not in fact a Linux distribution, it is a VM at91sam7x256 runs a at91sam7x256 micro-kernel with Linux as a virtualised guest At91sam7x256. Rules — please read before posting Post long source code as attachment, not in the text Posting advertisements is forbidden.


If you want to take advantage at91sam7x256 communications devices and storage media of at91sam7x256 types Linux may be a good choice.

I suggest then that you simple Google “ARM9 at91sam7x256 board” if you still think you need this. At91sam7x256 don’t ask any new questions in this thread, but start a new one.

But in any case you will need external Flash and RAM and a whole lot of infrastructure, so it’s best to start with a board that already comes with at91sam7x256 working Linux distribution, otherwise at91sam7x256 may be soon get frustrated. That is a question probably best answered by checking out the project’s own web site.

How much is at91sam7x256 cost”?

Consider something more suited to small devices such as eCos if you need real-time and extensive at91sam7x256 support, or FreeRTOS is you simply need a real-time preemptive at91sam7x256 based scheduler. Ok thank you, I got it ecos or freertos are the at91sam7x256 suitable for my application.

I think eCOS may be more appropriate however. Also no usable Linux distribution will run in the on-chip memory resources; you’ll need a board with external RAM and unless you at91sam7x256 from removable media, external Flash too.

RTLinux however has even more complex requirements that regular Linux. Linux is a general purpose OS, if at91samm7x256 application is very specific and small, you will be spending more at91sam7x256 hardware to support the OS than is strictly necessary to implement the application. I at91sam7x256 that it’s at91sam7x256 necessary to make it with embedded linux kernel At91sam7x256 I want to do so to familiarise with embedded linux.

There are distributions of Linux that at91sam7x256 run without at91sam7x256 MMU uClinux for examplebut just because you can, does not mean you would want to.
