That is at91sam7x256 question probably best answered at91sam7x256 checking out the project’s own web site. There are distributions of Linux at91swm7x256 will run without an MMU uClinux for examplebut just at91sam7x256 you can, does not mean you would want to.
Linux is a general purpose OS, if at91sam7x256 application is very specific and small, you will be spending more on hardware to support the At91sam7x256 than is at91sam7x256 necessary to implement the application. RTLinux however has even more complex requirements that regular Linux.
I agree, this is not the kind of controller that you would run Linux on. I think eCOS may be more appropriate at91sam7x256. Consider at91sam7x256 more suited to small devices such as eCos if you need real-time and extensive device support, or At91sam7x256 is you wt91sam7x256 need a real-time preemptive priority based scheduler.
How much is “low cost”? That is just teh requirement to get the OS to run. Despite its name it is at91sam7x256 in fact a Linux distribution, it is a VM that runs a real-time micro-kernel with At91sam7x256 as a at91sam7x256 guest OS.
If you want to take advantage of communications devices and at91sam7x256 media at91zam7x256 various types Linux may at91sam7x256 a good choice.

Programming At91SAM7x –
Rules — please read before posting Post long source code as attachment, not in the text Posting advertisements is forbidden. I know that it’s not necessary to make it with at91sam7x256 linux kernel But I want to do so to familiarise at91samx256 embedded linux. Also at91sam7x256 usable Linux distribution st91sam7x256 run in the on-chip memory resources; you’ll need a board at91sam7x256 external At91sam7x256 and unless you boot from removable media, external Flash too. Please don’t ask any new questions in this thread, but at91sam7x256 a new one.

Watch this topic Disable at91sam7x256 view. If you need hard real-time performance and small memory footprint, Linux would not be appropriate.
Lack of memory protection removes at91sam7x256 major advantage of using Linux. But in any case you will need external Flash and RAM and at91sam7x25 whole lot of infrastructure, so it’s best to start with a board at91sam7x256 already comes with a working Linux distribution, otherwise you may be at91sam7x256 get frustrated.
I suggest then that you simple Google “ARM9 at91sam7x526 board” if you still think you need this. at91sam7x256
Do you advise me to switch to at91sam7x256 ARM9 MCU if so can you, please, recommand me a at91sam7x256 cost board that have these features?
